How to Sterilize Sex Toys: Safe Methods for Every Material

Most of us wash a sex toy with soap and water, rinse it, and put it away. For everyday use, that is usually enough. However, some situations call for extra care. Good hygiene is essential when you share toys with a partner, switch between types of use, or clean a toy after an infection.

Knowing how to sterilize sex toys can help you choose the right cleaning method for each situation. Not every toy can withstand boiling water, rubbing alcohol, or high heat. Some materials may melt, crack, or lose their finish when exposed to unsuitable cleaning products.

The safest approach starts with the toy’s material and care instructions. Once you know what it can handle, keeping it clean becomes much easier. Here is what you should know about cleaning, disinfecting, and caring for different types of sex toys.

Sterilizing vs. Sanitizing vs. Disinfecting: Key Differences

Cleaning, sanitizing, disinfecting, and sterilizing all address germs, but they do not provide the same level of protection. Knowing what each process does will help you choose a suitable method for your toys.

Here is how they differ:

• Cleaning: This method is the standard way to wash a toy. Warm water and mild, unscented soap remove lubricant, bodily fluids, skin cells, and surface dirt. Although cleaning does not kill every microorganism, it removes much of the material that can carry germs.
• Sanitizing: Sanitizing lowers the number of certain microorganisms on a surface. If you want to know how to sanitize sex toys, check whether the cleaning product is actually approved for this purpose. An antibacterial claim alone does not guarantee effective sanitization.
• Disinfecting: Disinfection uses an approved method or product to destroy specific microorganisms on suitable surfaces. Knowing how to disinfect sex toys means understanding the product’s instructions, including its recommended contact time and material restrictions. Not every household disinfectant is safe for intimate products.
• Sterilizing: Sterilization aims to eliminate all forms of microbial life, including bacterial spores. This requires controlled conditions and validated equipment. Ordinary household cleaning methods should not automatically be described as medical sterilization.

The Truth About True Sterility

Boiling a sex toy or putting it in the dishwasher does not automatically make it medically sterile. Hospitals use controlled processes, such as autoclaves, to sterilize suitable equipment. These machines use pressurized steam under specific conditions.

Home cleaning methods do not necessarily meet those standards. Even if a toy can be boiled, it’s more accurate to describe the process as heat treatment rather than guaranteed medical sterilization.

For personal use, thorough cleaning and material-appropriate disinfection are generally more practical. The main goal is to remove bodily fluids and reduce the risk of spreading harmful microorganisms without damaging the toy.

When Should You Sterilize Sex Toys?

Regular washing is usually sufficient for personal use. However, some situations require extra care, especially when bodily fluids may pass between users or different parts of the body.

Pay closer attention to cleaning in these situations:

• Sharing a toy with a partner: Bodily fluids can transfer between users. A new condom or other suitable barrier for each person can help reduce contact, but it does not replace cleaning before and after use.
• Switching from anal to vaginal use: Never move a toy directly from the anus to the vagina. Rectal bacteria can cause infections when transferred to the vaginal area. Wash the toy thoroughly and change the condom or barrier before switching.
• Using a toy after an infection: If you have had a yeast infection, bacterial vaginosis (BV), or an STI, clean the toy carefully before using it again. Choose a method that suits the material and follow any advice from your healthcare provider.
• Taking a toy out of storage: Dust, lint, and residue can collect on stored products. Even if you washed the toy before storing it, wash it again before use.
• Noticing visible dirt or residue: Lubricant and bodily fluids can collect around seams, openings, and textured areas. Pay particular attention to these spots during cleaning.

If you have had a yeast infection or BV, cleaning matters because sex toys may contribute to recurrence if they still carry yeast or bacteria. A nonporous toy that is washed, fully dried, and properly stored is easier to keep clean than a soft, porous one. If symptoms return or don’t improve, check in with a healthcare provider instead of relying only on toy cleaning.

Know Your Toy’s Material First

Check what your toy is made of before using boiling water or any cleaning product. Some materials tolerate heat, while others can warp, crack, or deteriorate when exposed to it.

The packaging, product description, or manufacturer’s care guide should identify the material. If you need more information, our body-safe sex toy materials guide explains the common materials used in sex toys, their differences, and how to care for them.

Nonporous Materials That Are Easier to Clean

Nonporous materials have surfaces that do not readily absorb bodily fluids. They are generally easier to wash and maintain than porous alternatives.

Common examples include:

• Platinum-cured silicone
• Borosilicate glass
• Stainless steel, including suitable 316L products
• Properly finished ABS plastic

These materials are often excellent choices if easy cleaning is a priority. However, a nonporous surface does not automatically mean a toy can withstand high temperatures. Its shape, coatings, adhesives, and internal components also affect which cleaning methods are safe.

Porous Materials That Need Extra Caution

Some soft materials have tiny openings or surface structures that can hold moisture and residue. These include:

• TPE and TPR
• Jelly and rubber blends
• Cyberskin, UR3, and similar realistic soft-touch materials

You cannot reliably sterilize these products at home. Washing removes surface residue, but it cannot guarantee that all microorganisms have been removed from the material.

Let porous toys dry completely after washing. A fresh condom can provide an additional barrier during use, although it does not make a damaged or contaminated toy safe.

If the toy was used during an infection, replacing it is the safer choice, particularly if it’s made from a porous material.

How to Sterilize Silicone Sex Toys

Silicone is a popular choice because it is durable, smooth, and relatively easy to clean. Solid, nonporous silicone can also tolerate certain heat treatments. Still, not every silicone toy is suitable for boiling or dishwasher cleaning.

Before choosing a method, check the manufacturer’s instructions. Remove any detachable components that should not come into contact with water or heat.

Boil Them in Water

Can you boil sex toys? Yes, provided the toy is made from heat-resistant, solid silicone and has no motor, battery, charging port, or other heat-sensitive parts.

Follow these steps if the manufacturer approves boiling:

• Wash the toy with mild, unscented soap, then rinse away any visible residue.
• Fill a clean pot with enough water to cover the toy.
• Bring the water to a boil, then carefully lower the toy into it using clean tongs.
• Keep the toy from resting against the hot bottom of the pot if direct contact could damage its surface.
• Follow the manufacturer’s recommended heating time. Do not assume every silicone product can tolerate the same duration.
• Remove the toy carefully and allow it to cool completely.
• Let it air-dry on a clean surface, or use a clean, lint-free cloth.

Never boil a vibrating toy or any product with electronic components. High heat can damage its internal parts even if its exterior is waterproof.

Run Them Through the Dishwasher

Some solid silicone and glass toys can go in the dishwasher, but only when the manufacturer says it’s safe.

If the care instructions approve this method:

• Place the toy securely on the top rack.
• Keep small products inside a suitable dishwasher basket.
• Avoid using scented or harsh detergents that may leave residue.
• Do not add other items that could scratch or contaminate the toy.
• Allow it to cool and dry completely before storage.

A dishwasher’s cleaning cycle does not guarantee sterilization. High temperatures and detergents can also damage certain finishes and materials, so check the product instructions before using this method.

Wipe Them With Rubbing Alcohol

Rubbing alcohol is sometimes suggested for cleaning nonporous surfaces, but it is not suitable for every sex toy.

Some manufacturers permit the use of 70% isopropyl alcohol on certain products. Others advise against it because alcohol may affect silicone finishes, adhesives, coatings, or other components.

If alcohol cleaning is approved for your toy, follow the recommended application method. Keep it away from charging ports, seams, and exposed electronic components. Allow the surface to dry fully before use.

Avoid using alcohol on porous materials such as TPE and jelly. It may damage these surfaces without reliably disinfecting the material beneath them.

How to Sterilize a Dildo

Dildos come in many shapes, sizes, and materials. A solid silicone dildo requires different care from a vibrating model or a soft TPE product.

The cleaning method depends on the type of dildo you own:

• Solid silicone, glass, or stainless steel dildos: Wash with mild soap and warm water after use. If the manufacturer approves it, you may also boil a suitable solid product or run it through a dishwasher cycle.
• Vibrating or motorized dildos: Check the waterproof rating before washing. Clean the exterior with a damp cloth or mild soapy water, following the manufacturer’s instructions. Keep charging ports and other openings dry. Do not use rubbing alcohol unless the manufacturer specifically permits it.
• TPE and other soft-material dildos: Gently wash the surface with mild soap and warm water. Avoid boiling, harsh chemicals, and high heat. Dry completely before storage.
• Harnesses and attachments: These may combine silicone, plastic, fabric, and metal parts. Clean each component according to its material and care label. Fabric straps may require separate hand-washing.

The outer material is not the only thing to consider when choosing how to sterilize a dildo. A silicone product may still contain adhesives, metal components, or electronics that cannot tolerate heat.

Do You Need a Sex Toy Sterilizer?

A sex toy sterilizer can make cleaning more convenient, especially if you own several products. However, most people can maintain good hygiene without buying one.

Products sold as sex toy sterilizers generally use UV light, steam, or another cleaning technology. Toys function differently depending on the device, the material, and how they’re used.

UV Sterilizers

UV light may not reach grooves, seams, recessed areas, or surfaces that are blocked from direct exposure.

UV treatment also does not remove lubricant, bodily fluids, or visible dirt. Wash the toy before using a UV device.

Steam Sterilizers

Steam devices use heat and moisture to treat suitable items. Some are designed for personal accessories, but their operating temperatures and conditions vary. Do not assume a steam cleaner can achieve medical-grade sterilization.

Are These Devices Worth Buying?

A sterilizer may save time if you own several compatible toys and prefer using one cleaning device. However, it still cannot replace regular washing and proper drying.

For everyday maintenance, mild soap, clean water, and suitable storage are generally sufficient. A specialized device is an optional convenience, not something every toy owner needs.

Common Sterilizing Mistakes to Avoid

Using the wrong cleaning method can damage a toy or leave unwanted residue behind. Watch out for these common mistakes:

• Boiling toys with batteries inside: Never boil a product with a motor, battery, or charging port. Even waterproof electronics are not necessarily designed to withstand boiling temperatures.
• Using bleach, vinegar, or harsh household cleaners: These products may damage silicone, rubber, coatings, and other materials. They can also leave irritating residues. Only use manufacturer-approved cleaning products.
• Using rubbing alcohol without checking compatibility: Alcohol can affect certain finishes and materials. Do not assume it is safe for every nonporous toy.
• Microwaving sex toys: Never put a sex toy in the microwave. Uneven heating can damage the material, while hidden metal components may cause sparks.
• Skipping the rinse: Soap and cleaning products can leave residue if they are not rinsed off thoroughly. Follow the product instructions and make sure the surface is clean before use.
• Putting toys away while wet: Moisture trapped in seams, crevices, or storage containers can encourage mold and unpleasant odors. Allow the toy to dry completely first.

Drying and Storing Clean Sex Toys

Cleaning is only one part of proper toy care. Drying and storage matter too, especially when moisture can collect around seams and textured surfaces.

After washing or using an approved cleaning method:

• Gently shake off excess water.
• Pat the surface with a clean, lint-free cloth.
• Check seams, openings, and textured areas for trapped moisture.
• Allow the toy to air-dry completely before storing it.
• Keep each product in a separate breathable pouch or suitable container.
• Avoid placing soft toys directly against other soft toys unless the manufacturer confirms that the materials are compatible.
• Store products away from direct sunlight, extreme heat, and excessive humidity.
• Pay special attention to areas that are difficult to reach with a cloth.

Frequently Asked Questions About Sterilizing Sex Toys

Can you boil sex toys to sterilize them?

Only if the manufacturer confirms that the toy can withstand boiling; suitable solid silicone, borosilicate glass, and stainless steel products may tolerate this method. Never boil porous toys or products containing motors, batteries, or other heat-sensitive components. Boiling also does not guarantee medical-grade sterilization.

How do you sterilize sex toys without sex toy cleaner?

You don’t need a specialized cleaner for everyday washing. Mild, unscented soap and warm water are generally suitable for many nonporous toys. For additional treatment, follow the manufacturer’s instructions for the material. Do not use boiling water or other heat treatments unless the product is approved for them.

Can you use rubbing alcohol to sterilize sex toys?

Rubbing alcohol does not ensure sterilization and should be avoided on porous materials like TPE or jelly.

How do you clean a vibrator after a yeast infection or BV?

Start by checking the vibrator’s material and waterproof rating. Wash it with mild soap and water if the care instructions allow it. For a suitable solid silicone vibrator without electronics, the manufacturer may approve boiling. Motorized products require the recommended surface-cleaning method, with charging ports and electrical openings kept dry.

If the vibrator is porous, damaged, or difficult to clean thoroughly, replacing it may be safer. Speak with a healthcare provider if symptoms persist or return after treatment.

What is the difference between cleaning, sanitizing, and sterilizing a sex toy?

Cleaning removes bodily fluids, lubricant, and dirt using soap and water. Sanitizing reduces certain microorganisms, while disinfecting destroys specific microorganisms on compatible surfaces. Sterilizing aims to eliminate all microbial life, including bacterial spores. These processes offer different levels of microbial control and should not be used interchangeably.

Make Sterilizing Part of Your Routine

Good care doesn’t have to spoil the fun. Once you get used to the routine, cleaning your toys becomes just another quick step, like washing your hands or locking the door. Give your toy a few minutes of attention, let it dry properly, and put it away. That way, you won’t have to keep worrying about germs, cleaning methods, or complicated checklists when it’s time to enjoy yourself.

Pleasure is easier when your mind isn’t busy doing hygiene math. Finish cleaning first so you can relax and enjoy the rest of the night.
