Body-safe materials explained: silicone, TPE, ABS, glass and metal

The short answer: non-porous materials — platinum-cure silicone, ABS plastic, borosilicate glass and stainless steel — can be cleaned properly and last for years. Porous materials — TPE, TPR, jelly, PVC — absorb moisture and bacteria, cannot be fully sterilised, and should be replaced within a year or so. "Body-safe" on its own is a marketing phrase, not a material.

Why porosity is the only question that matters

A material is either porous or it is not, and almost everything else follows from that.

Non-porous surfaces do not let moisture or microbes into the material itself. You can wash them, dry them, and reuse them indefinitely. Porous surfaces have microscopic channels that hold moisture, lubricant and bacteria, which is why a porous toy eventually smells different no matter how carefully you wash it — the surface is clean but the inside of the material is not.

That single fact drives cleaning, sharing, lifespan and price. It also explains why two products that look identical can cost three times different amounts.

The five materials you will actually encounter

Two entries in that table are worth dwelling on.

Silicone. Real silicone is expensive to produce, which is why it appears at the top of the price range. It warms to body temperature, does not hold odour, and survives years of use. The one rule is lubricant: silicone-based lubricant can soften or swell a silicone surface, so water-based or hybrid is the safe pairing.

TPE. Not a cheat, just a different proposition. It is softer than silicone, cheaper to make, and short-lived. If you buy TPE knowingly and replace it when the surface becomes tacky, it does its job. The problem is buying it at a silicone price because the listing was vague.

How to read a listing that says "body-safe"

Work down this list and stop at the first item that applies.

1. Is the material named? "100% platinum-cure silicone" is a specification. "Body-safe material" is not.
2. Is the material named for every variant? A listing that names silicone for the black version and says "safe material" for the pink one is hiding something.
3. Are there safety standards cited? US and EU markets reference FDA-grade or EU food-contact standards for silicone; a serious seller will name one.
4. Is the price plausible? Silicone of the size of a palm-sized vibrator at a fifth of the usual price is not silicone.
5. Does it smell? A strong chemical or plastic smell on a new item is a reason to return it, not to wash it.

Cleaning rules that hold for every material

• Wash with warm water and a mild, unscented soap before first use and after every use. Dedicated cleaners are convenient, not essential.
• Dry completely before storage. Moisture in a closed pouch is how porous materials go wrong.
• Store separately, ideally in a fabric pouch. Silicone stored touching silicone can bond over time.
• Do not boil or dishwasher anything that contains a motor, a battery or a charging port, whatever the listing says.
• Replace porous items once the surface feels tacky, looks discoloured, or smells different after washing. That is the material failing, not the cleaning.

Lubricant compatibility, in one table

If you want one bottle that works with everything, buy water-based. It needs reapplying more often, which is the only real cost.

When to spend more

Spend on material first, then on noise and waterproofing, then on features. App control, patterns and heating are the expensive extras, and they are the first things people stop using. A quiet, non-porous, well-sealed device at a mid-range price will see more use than a feature-heavy one with a porous surface.

Frequently asked questions

Is TPE safe?

TPE is generally considered safe for external use when it is phthalate-free, but it is porous, so it cannot be fully cleaned and should not be shared between partners without a condom. It also degrades faster than silicone.

Can I use silicone lubricant with a silicone toy?

It is not recommended. Silicone-based lubricant can soften or swell the surface of a silicone toy over time. Use water-based or hybrid lubricant instead, and save silicone lubricant for glass, steel or condoms.

How often should I replace a toy?

Silicone, glass and steel last years if they are undamaged. TPE and jelly should be replaced every six to eighteen months, or sooner if the surface becomes tacky, discoloured or holds odour after washing.

Does "medical-grade" mean anything?

It is used loosely. The underlying claim you want is a named material plus a named standard — for example platinum-cure silicone meeting a food-contact or medical-grade standard. Without either, treat it as marketing.
