Storing Silicone Toys: Common Mistakes and the Right Method
Share
TPE toys become oily and sticky in the closet – even without use. This is plasticizer migration, not a storage error. Platinum silicone does not structurally change with proper storage. The rules: dry, dark, separate, in cotton – not in plastic, not together with other toys.
"I haven't used my toy in months – and now it's sticky and smells weird." This is one of the most common posts on Reddit, in sex toy forums, and in product reviews. Most answers are: "Normal for TPE, buy something better." That's true – but it doesn't explain why it happens and how to prevent it next time. This guide does both.
Why TPE Toys Get Destroyed in the Closet – Without Use
This is the part hardly any manufacturer explains: TPE toys don't just degrade through use. They degrade through time and storage – regardless of whether you use them or not.
The Chemistry Behind It: Plasticizer Migration at Rest
TPE contains plasticizers – chemical compounds that make the material soft. These plasticizers are not chemically bonded. They are physically enclosed and continuously migrate outwards – even if the toy is in the closet and not touched.
What accelerates migration:
- Heat: A closet in a warm room (25°C+) significantly accelerates migration. In summer, a toy can become sticky in a few weeks, which would have lasted months in winter.
- Contact with other materials: If a TPE toy touches a plastic bag, migration into the plastic film can be accelerated – and conversely, plasticizers from the film can migrate into the toy.
- Contact with other toys: Two TPE toys stored together mutually accelerate their degradation. A TPE toy next to a platinum silicone toy can contaminate the silicone surface.
- Pressure: A toy that is under other objects degrades faster at the pressure points.
"I left my TPE toy in a plastic bag in the drawer. After 3 months, it was sticky, oily, and smelled chemical. I thought I had cleaned it incorrectly."
No – you stored it incorrectly. But even correct storage would have only slowed down the process, not stopped it. This is the fundamental problem of TPE.
What Cornstarch Really Does – and What It Doesn't
Many Reddit users recommend treating TPE toys with cornstarch or baby powder before storage. This temporarily reduces the stickiness of the surface – but it does not stop plasticizer migration from within the material. After a few weeks, the toy becomes sticky again because new plasticizers have migrated to the surface.
Cornstarch is symptom treatment, not a solution. The solution is the material.
Why Platinum Silicone Doesn't Have This Problem
Platinum silicone contains no plasticizers. The softness results from the cross-linking process itself – not from chemical additives. There is nothing that could migrate. A platinum silicone toy that you put in a drawer today will feel the same a year from now – provided you avoid the following storage mistakes.
The 6 Most Common Storage Mistakes – Even with Platinum Silicone
Mistake 1: Storing in a Plastic Bag
Plastic bags trap moisture and can release chemical compounds with some plastics. For TPE, this accelerates degradation. For platinum silicone, the risk is lower – but moisture in the bag can promote mold on the storage surface.
Solution: Cotton or satin bags. They allow air to circulate, keep dust away, and do not release any substances.
Mistake 2: Packing While Wet
A toy that is still damp after cleaning and is packed immediately creates a moist environment in the bag. This is not a problem for the platinum silicone itself – but for the storage environment. Mold on the bag surface is a hygiene problem.
Solution: Allow to dry completely – air drying or a clean cloth. Do not use a hairdryer on the highest setting directly on the surface.
Mistake 3: Storing with Other Toys
This is the most critical mistake for platinum silicone owners: A TPE toy that lies directly next to or on a platinum silicone toy can transfer plasticizers to the silicone surface. The result: sticky contact points on the otherwise high-quality toy.
Solution: Each toy in its own bag. Never store two toys together without separation – even if both are made of platinum silicone (color transfer is possible with intense pigments).
Mistake 4: Storing in Direct Sunlight or Heat
UV radiation can affect pigments in the long term. Heat significantly accelerates plasticizer migration in TPE. For platinum silicone, heat is not a structural problem – but pigment changes with intense colors are possible.
Solution: Store in the dark. Closet, drawer, opaque box – no windowsill, no direct light.
Mistake 5: Storing Under Pressure
A toy that lies under books, other objects, or in an overcrowded cabinet will be permanently deformed at the pressure points. With TPE, this is irreversible. With platinum silicone, the material returns after relief – but very long pressure can cause permanent deformations.
Solution: Store upright or flat without pressure. No heavy objects on the toy.
Mistake 6: Never Cleaning Before Storage
Lubricant residues, bodily fluids, or skin particles on the surface are a breeding ground for bacteria – even if the toy is in the closet. Platinum silicone is not porous, but the surface is not sterile if it has not been cleaned.
Solution: Always clean before storage. Soap and warm water, lather for 30 seconds, rinse thoroughly, then pack.
Perfect Storage: Step-by-Step
- Clean after use: Soap + warm water, lather for 30 seconds, rinse thoroughly
- Dry completely: Air dry or with a clean cloth – no hairdryer on the highest setting
- Pack in a cotton bag: Each toy individually, no plastic
- Store in the dark: Drawer, closet, opaque box
- Separate from other toys: Especially important if you still own TPE toys
- Without pressure: No heavy objects on the toy
Storage by Product Type
| Product Type | Storage Specificity | Recommendation |
|---|---|---|
| Realistic / Fantasy Dildo | Upright or flat, no pressure on textured elements | Own cotton bag, standing if possible |
| Pocket Pussy | Allow inner channel to dry completely | Dry open, then pack – never close wet |
| Penis Sleeve | Do not store rolled up – deformation possible | Flat or over a holder, own bag |
| Transgender Vaginas | Store flat, do not fold | Flat, wrapped in cotton cloth |
| Penis Ring | Do not store overstretched | Flat, relaxed, own small bag |
What to Do with Old TPE Toys?
If you already own TPE toys that are sticky or oily: dispose of them. Do not store them with platinum silicone toys – even if they still seem "usable." The plasticizers that make them sticky can transfer to your high-quality toys.
If your TPE toys are not yet sticky: store them separately, in their own bags, far away from platinum silicone. And for your next purchase: platinum silicone.

Frequently Asked Questions
Why does my sex toy get sticky in the closet even though I haven't used it?
This is plasticizer migration: TPE toys contain plasticizers that are not chemically bonded and continuously migrate out of the material – even without use, even in the closet. Heat and contact with other materials accelerate the process. Platinum silicone contains no plasticizers and will never become sticky on its own.
Can I store my sex toy in a plastic bag?
Not recommended. Plastic traps moisture and can release chemical compounds. For TPE, this accelerates degradation. For platinum silicone, the risk is lower, but cotton or satin bags are always better – they allow air to circulate and do not release any substances.
Can I store two silicone toys together?
Only if both are platinum silicone and in their own bags. Never a TPE toy directly next to a platinum silicone toy – plasticizers can transfer to the silicone surface. Even with two platinum silicone toys: separate bags are recommended to avoid color transfer with intense pigments.
Does cornstarch help with storing TPE toys?
Temporarily yes – cornstarch absorbs the oily surface substances and makes the toy temporarily less sticky. However, it does not stop plasticizer migration from within the material. After a few weeks, the toy will become sticky again. Cornstarch is symptom treatment, not a solution.
How long can I store a platinum silicone toy?
Indefinitely – if you store it correctly. Platinum silicone does not structurally degrade through storage. Dry, dark, separate in a cotton bag – the toy will be in the same condition after a year as after a week.
