What Lube Is Safe for Your Sex Toy?

You’ve got the toy in one hand and a bottle of lube in the other, and somewhere between the two you’ve realised you’re not certain they go together.

It’s a fair question, and far more people ask it than you’d think. Water-based lube is safe with every toy material there is. The one genuine landmine is silicone lube on a silicone toy, which is why picking the right lube for silicone toys matters more than almost anything else in your bedside drawer.

Below we’ve broken it down by what your toy is actually made of, because that’s the bit that decides everything.

The quick answer: which lube goes with which toy:

If you remember nothing else from this page, remember this: water-based works with everything. It’s the answer whenever you’re unsure, whenever you’ve lost the box, and whenever you can’t quite tell what a toy is made from.

The best lube for silicone toys, and why silicone lube isn’t it:

The reason comes down to chemistry, and it’s simpler than it sounds. Like dissolves like.

A silicone toy and a silicone lubricant are built from related polymers. Put them together and the lube doesn’t sit politely on the surface the way a water-based one does. It absorbs into the cured silicone and starts behaving like a solvent, softening the outer layer from the outside in.

That’s why you can’t wash it off afterwards and undo the damage. There’s nothing sitting on top to remove. The surface itself has changed.

It’s faster than people expect, too. Not a slow decline over years of use. A toy can come out of one session feeling tacky where it used to feel smooth.

Toy by toy: what to use:

Silicone

Silicone is the material most good toys are made from, and for good reason. It’s non-porous, body-safe, easy to clean properly, and it warms to your body temperature rather than staying stubbornly cold. Most quality vibrators, dildos, plugs, and prostate massagers are silicone. It’s also the one material with a rule attached. Water-based lube only. If your toy feels smooth and slightly matte, has a bit of give when you squeeze it, and came from a brand you recognise, it’s almost certainly silicone.

TPE and TPR

TPE and TPR (thermoplastic elastomer and thermoplastic rubber) turn up in stretchy sleeves, realistic dildos, and anything with that soft, squashy, skin-like feel. They’re body-safe, but unlike silicone they’re porous. The surface has microscopic openings that hold onto bacteria and absorb whatever you put on them. The right lube for TPE toys is water-based, same as silicone, and be thorough with cleaning. Porous materials have a shorter working life than silicone whatever you use on them.

ABS plastic

This is the hard, rigid plastic in bullet vibrators, wand heads, and a lot of clitoral toys. It’s non-porous and chemically inert, which is a technical way of saying it doesn’t react with anything. Water-based or silicone lube, take your pick.

Glass

Borosilicate glass is inert, so the best lube for glass toys is whichever one you like the feel of. Nothing you’re likely to own will react with it. It’s easy to sterilise, and it holds temperature if you fancy warming or cooling it first.

Stainless steel

Same story. Non-reactive, compatible with every lube type, weighty in a way a lot of people love, and about as easy to clean as a toy gets

How to tell if a toy has been damaged:

If you’re reading this because something’s already gone wrong, you’re in very good company. It’s one of the most common things customers bring to us.

What to look for:

• Tacky or gummy patches where the surface used to be smooth
• A surface that grips your skin instead of gliding across it
• Small pits or dimples in the material
• Discolouration, often a patchy dulling
• Flaking, in the worst cases

None of it washes off. If a toy has gone sticky and stays sticky after a proper clean, the material itself has changed.

Now the part nobody enjoys saying. A degraded silicone surface is no longer non-porous, which means it can hold bacteria in a way an intact one can’t. That makes it harder to get properly clean, and it’s why we’d tell you to retire a badly affected toy rather than nurse it along.

Coconut oil, baby oil, and why they’re really a condom problem:

Coconut oil comes up constantly, so let’s deal with it properly.

Oil-based lubricants aren’t primarily a toy problem. Glass, steel, and hard plastic will shrug them off entirely. The real issue is condoms. NHS guidance is clear that oil-based products, including body oil, lotion, and petroleum jelly, damage latex and polyisoprene condoms and make them far more likely to burst. If condoms are part of your evening, oils are out. They’re also difficult to wash off any surface, and a poor idea on anything porous, since the material will hold onto them. Oils can upset your natural pH balance too. There are better options sitting on the shelf.

What we’d actually reach for:

Rather than list specifications at you, this is how we’d steer you in store.

If you want one bottle that handles everything, a straightforward water-based lubricant is the answer. It works with every toy you own and every condom on the shelf. Expect to pay under £15 for a decent one, and look for a pump if you’d rather not fumble with a cap.

If you’re using toys for longer sessions, go for a thicker water-based formula rather than switching to silicone. They hold their slip far longer than the thin, glossy ones, so you’ll reapply much less often.

If you’re playing anally, you want thickness above all else. A dedicated anal lubricant is worth the small extra outlay, and the water-based ones are still safe with a silicone plug or dildo.

If you genuinely want silicone lube, buy it for what it’s actually good at. It’s excellent for skin-to-skin and it won’t rinse away in the shower. It’s fine with glass and steel, too. Just keep it away from your silicone.

The bottom line:

Getting this right isn’t complicated once you know what you’re holding. Silicone and TPE get water-based lube. Glass, steel, and hard plastic will take whatever you’ve got. And if you can’t work out which camp your toy falls into, water-based will never let you down.

Have a look through our range of water-based lubricants when you’re ready to restock, or our anal lubricants if that’s what the evening calls for.
