Never use silicone-based lube with silicone toys. That's it. That's the rule everything else flows from.
Silicone lube bonds to silicone toy material at a molecular level. It doesn't wash off or wipe away - it degrades the surface from the outside in. The toy becomes sticky, tacky, or pitted. In some cases the surface starts to flake. The damage is permanent and it can happen within a single session.
This matters because the majority of quality sex toys - most vibrators, most dildos, most anal toys - are made from silicone. And silicone lube is often marketed as the long-lasting, skin-friendly, superior option. Both of those things are true. It just can't go near silicone toys.
For everything else, the rules are simpler. Water-based lube is safe with every toy material without exception. It's the universal answer if you're ever unsure.
Toy materials explained
Sex toy packaging is often vague about materials. "Body-safe" is a marketing phrase, not a material specification. You need to know the actual material to choose lube correctly.
Silicone is the gold standard. It's non-porous, body-safe, easy to clean, and used in most high-quality vibrators, dildos, butt plugs, and prostate massagers. It's also the material that reacts with silicone lube. If your toy is smooth, slightly matte or slightly shiny, firm but with some give, and came from a reputable brand, it's almost certainly silicone.
ABS plastic is the hard, rigid plastic used in many bullet vibrators, wand massager heads, and cheaper clitoral toys. It's non-porous and chemically inert, which means it doesn't react with silicone lube. It's safe with water-based or silicone lube.
TPE and TPR (thermoplastic elastomer and thermoplastic rubber) are softer, flexible materials found in many realistic dildos, masturbation sleeves, and stretchy toys. They're body-safe but porous, meaning they can harbour bacteria and absorb substances. Use water-based lube only. These materials do not play well with silicone lube.
Glass is completely inert. Borosilicate glass toys react with nothing. You can use water-based, silicone, or even oil-based lube on glass. Glass toys are also easy to sterilise.
Stainless steel is the same - completely non-reactive, compatible with all lube types. Steel toys are often heavier, temperature-responsive, and very easy to clean.
Latex is found in some older toys and some stretchy sleeves and cock rings. Oil-based lube degrades latex just as it degrades latex condoms - avoid it. Water-based and silicone lube are both fine with latex.
"Jelly" or rubber toys (soft, translucent, often cheap) are porous and frequently contain phthalates. These are the worst materials for body safety and lube compatibility. If you have old jelly toys, either use a condom on them every time or replace them.
If you're unsure whether your toy is silicone, do the pinch test. Apply a tiny amount of silicone lube to an inconspicuous area of the toy and wait 10 minutes. If the surface becomes tacky or sticky, it's silicone. Stop using silicone lube on that toy immediately.
The lube compatibility chart
Use this as a quick reference before reaching for any lube.
| Toy material | Water-based lube | Silicone-based lube | Oil-based lube |
|---|---|---|---|
| Silicone | Safe | NOT SAFE | Not recommended |
| ABS plastic (hard) | Safe | Safe | Not recommended |
| Glass | Safe | Safe | Safe |
| Stainless steel | Safe | Safe | Safe |
| TPE/TPR | Safe | NOT SAFE | Not recommended |
| Latex | Safe | Safe | NOT SAFE |
Oil-based lube is listed as "not recommended" rather than "not safe" for most materials because the issue isn't chemical damage - it's that oil is difficult to clean from toys and can create an environment for bacterial growth. Glass and steel are the exception because they sterilise easily.
Best water-based lubes for toys
Water-based lubricants are the right default choice for any toy. They're universally compatible, easy to clean, and condom-safe if you're using a condom on your toy.
The trade-off is longevity - water-based lube dries out faster than silicone lube and needs reapplication. Thicker gel formulas perform better than thin liquid formulas for toy use because they stay in place longer and don't evaporate as quickly.
Durex Feel Lube is a reliable all-rounder. It's widely available, reasonably priced, water-based, and doesn't contain glycerin (which matters if you're prone to infections). The formula is smooth without being thick - it works well with most vibrators and dildos.
pjur Aqua is one of the better quality water-based options on the market. It has a slightly thicker consistency than most drug store lubes, which means it lasts longer without reapplication. It's fragrance-free and pH-balanced. If you find standard water-based lubes dry out too quickly during toy use, pjur Aqua is worth the step up.
Sliquid H2O is a clean-formula favourite. No glycerin, no parabens, no added fragrance. It's formulated specifically to be gentle on body chemistry, which makes it a good choice for people who find some lubes irritating. The consistency is lighter than pjur Aqua but it performs well with both internal and external toys.
SKYN lube is another solid water-based choice, particularly if you already use SKYN condoms and want a consistent product pairing. It's compatible with all toy materials and latex condoms.
The honest note on all water-based lubes: they will need reapplication more often than silicone lube. That's not a flaw - it's the trade-off you accept for universal compatibility. Keep the bottle within reach.
When silicone lube is fine with toys
Silicone lubricants are long-lasting, don't dry out, and are often the best-feeling lube for skin contact. They're completely safe to use with certain toy materials.
You can use silicone lube freely with glass toys, stainless steel toys, and hard ABS plastic toys. None of these materials react with silicone. A glass dildo with silicone lube is an excellent combination - the lube doesn't absorb, doesn't dry out, and the glass is easy to clean afterwards.
Uberlube is the most recommended silicone lube for this use case. It's a four-ingredient formula (silicone, vitamin E, nothing else notable) with a very clean, almost dry finish. It performs exceptionally on glass and steel toys and is also popular as a skin lube for external stimulation.
The rule to repeat: silicone lube on glass, steel, and hard plastic only. Never on silicone toys, never on TPE or TPR, never on latex.
If you're using a silicone lube and you're not completely certain about your toy's material, don't. Use water-based lube instead. The risk isn't worth saving a few reapplications.
What happens if you use the wrong lube
The degradation from using silicone lube on a silicone toy doesn't always happen immediately. Sometimes the damage shows up after a single use. Sometimes it takes several uses over weeks. Either way, it's not reversible.
The first sign is usually a tacky or sticky surface where the toy previously felt smooth. The toy starts to feel like it hasn't been cleaned properly, even when it has. This is the silicone lube bonding to and breaking down the toy's surface layer.
As degradation continues, the surface can become pitted or uneven. In worse cases - particularly with lower-quality silicone toys - the surface can start to peel or break apart. At that point the toy is no longer body-safe and should be replaced.
The same principle applies with TPE and TPR materials. These are porous, and silicone lube can penetrate the surface and degrade the material structure over time.
Using oil-based lube on latex toys causes a different but equally serious problem: the latex breaks down. This matters whether you're talking about a latex toy or a latex condom being used on a toy. Oil weakens the latex structure, making it prone to tearing. If you're using a condom on a toy to manage hygiene, always use water-based lube with it.
The condom solution for porous toys
TPE, TPR, rubber, and jelly materials are porous. That means they can harbour bacteria even after cleaning. It also means they can absorb substances, including some lube ingredients.
The straightforward solution is to use a condom on any porous toy. Put the condom on first, then add water-based lube to the outside of the condom. This solves two problems at once: it creates a non-porous barrier that's easier to keep clean, and it removes the direct contact between lube and toy material.
This is also the recommended approach for sharing toys, regardless of material. A fresh condom each time is simpler and more reliable than sterilisation for most toy materials.
The condom method does not change the lube rules. Use water-based lube on the outside of the condom - not silicone lube, not oil-based lube, if the toy inside is silicone or TPE.
Best lube for specific toy types
Lube for a vibrator
Most vibrators are made from silicone or ABS plastic. The body of the toy (the shaft or head that contacts skin) is usually silicone; the external casing or buttons may be ABS plastic.
Use water-based lube. It's safe on silicone, it won't damage the toy, and it cleans off easily. If your vibrator is purely ABS plastic (common with bullet vibrators and some wands), silicone lube is technically fine - but water-based is still the simpler, safer default.
Avoid getting any lube into charging ports or battery compartments. Apply lube to yourself or to the relevant part of the toy, not to the whole device.
Lube for a dildo
Dildos come in silicone, glass, stainless steel, and TPE/TPR. Material determines lube choice.
Silicone dildos: water-based lube only. Glass and steel dildos: water-based or silicone, your preference. TPE/TPR dildos: water-based only.
For internal use, a thicker water-based gel tends to perform better than a thin liquid - it stays in place and needs fewer reapplications. pjur Aqua works well here.
Lube for masturbation sleeves
Almost all masturbation sleeves are made from TPE, TPR, or similar soft porous materials. Water-based lube is the only safe choice.
Use generously - these products work best when well-lubricated, and the internal texture increases friction. Reapply as needed. After use, clean thoroughly with warm water and let dry completely before storing.
Lube for anal toys
The anus doesn't self-lubricate, so lube isn't optional - it's necessary for comfort and safety. Use plenty of it.
Material determines lube type as with all toys. Silicone butt plugs and anal beads: water-based only. Glass or steel anal toys: water-based or silicone.
For anal use specifically, a thicker formula is preferable. Thin lubes dissipate quickly, which is a bigger problem during anal play than vaginal play. Look for water-based gel formulas or consider a dedicated anal lube that has a thicker consistency.
FAQs
Can you use silicone lube with sex toys?
Only with non-silicone toys. Silicone lube is safe on glass, stainless steel, and hard ABS plastic toys. It will degrade silicone and TPE/TPR toys over time, causing the surface to become sticky or pitted. If you're unsure of your toy's material, use water-based lube.
What lube is completely safe for all sex toys?
Water-based lube is safe with every toy material. It won't damage silicone, TPE, latex, glass, steel, or ABS plastic. It's the universal choice when you're unsure or when you're using multiple toys with different materials.
How do I know if my toy is silicone?
Check the product description or manufacturer's website first. If you can't confirm the material, do the pinch test: apply a small amount of silicone lube to an inconspicuous area of the toy and wait 10 minutes. If the surface becomes tacky, it's silicone. Stop using silicone lube on that toy.
Can I use coconut oil or other natural oils on toys?
Not if there's a latex element involved (toy or condom). Oil degrades latex. For glass or steel toys with no latex present, coconut oil and other natural oils won't cause chemical damage, but they're harder to clean from surfaces than water-based lube and can create hygiene issues. In practice, a good water-based lube is a better choice.
My silicone toy feels sticky - what happened?
It's very likely that silicone lube or an oil-based product was used on it. The sticky texture is the surface layer degrading. Unfortunately this isn't reversible. If the surface is only mildly affected, the toy is still usable but won't feel the same. If the surface is breaking down significantly, replace the toy - a compromised surface isn't safe for internal use.
Does lube affect how toys feel?
Yes, in a good way. Lube reduces friction, which makes most toy sensations more comfortable and often more pleasurable. For vibrators, it helps transmit vibration to skin more effectively. For insertable toys, it makes insertion easier and reduces any potential for micro-abrasion. Using lube with toys is always recommended, not just for safety but for the experience.
Do I need special lube for anal toys specifically?
You don't need a different product category, but you do want a thicker formula for anal use. Standard thin water-based lubes work but dissipate quickly. A water-based gel, or a lube specifically formulated for anal play with a thicker consistency, will last longer and perform better. The material compatibility rules are the same: check your toy's material and choose accordingly.
Is it safe to use lube with a condom on a toy?
Yes, provided you use the right lube. Use water-based lube on the outside of the condom - this is safe with latex condoms and covers all toy materials underneath. Never use oil-based lube with latex condoms. The condom plus water-based lube combination is the safest approach for porous toy materials.
