Is Your Lube Killing Your Vibrator? A Clinical Sexologist on Which Lube to Use for Toys, Anal, Condoms and Solo Play

by Heather Foord, Core Restore Co

There's a mistake happening in Australian bedrooms right now and it's quietly degrading some of the most expensive vibrators on the market.

It's not being talked about. It's not on the bottle. And it is the reason so many women message me saying their new toy suddenly 'feels weird.'

The mistake is using silicone lube with a silicone toy. And once you understand why, you will never do it again.

The silicone-on-silicone problem

Silicone is a bit of a diva. Silicone bonds to silicone. So when you put silicone lube on a silicone toy, the lube slowly reacts with the toy's surface, softening it, breaking it down and eventually leaving it with a sticky, chalky texture. It's not immediate. It happens over a few uses. And once the toy is compromised, that surface can start harbouring bacteria too.

If your favourite vibrator is silicone (and most premium body-safe ones are), you need a lube that does not fight with it. Which brings us to the good stuff.

Water-based lube: the everyday hero

Water-based is the most versatile lube on the market. It is safe with condoms, safe with every toy material (silicone, glass, metal, ceramic, ABS plastic, everything), non-staining and easy to clean up. It is the one to buy in bulk. This is what belongs in your bedside drawer as your daily driver.

The one downside is that it can dry out faster than silicone, so you may need to reapply. Not a big deal. A pump-top bottle by the bed sorts it.

Silicone lube: for the specific occasions

Silicone lube is longer-lasting, feels silkier and does not wash away in water, which makes it fantastic for shower and bath play. It is also the go-to for anal play because it stays slippery for the length of time you actually need it to.

Rule: silicone lube with anything except silicone toys. So use it with your body, with glass toys, with metal toys, in the shower and for anal. Never with your silicone vibrator.

Oil-based lube: solo only

Oil-based lubes (coconut oil, dedicated oil-based products) feel gorgeous and last forever, but they break down latex condoms and can trap bacteria in the vagina, upping your risk of infections. Reserve them for solo external play or massage. Skip them if you use condoms.

Hybrid lube: the compromise

Hybrid lubes are mostly water-based with a small amount of silicone for extra glide. They are usually silicone-toy safe and last longer than pure water-based. A great middle-ground option if you want the everyday flexibility of water-based with a touch more longevity.

Vaginal moisturisers versus lube (because they are not the same thing)

This one trips a lot of women up. Lube is for the moment. Vaginal moisturisers are for the underlying tissue. If you experience ongoing dryness (breastfeeding, perimenopause, some medications), a vaginal moisturiser used every few days can help the tissue itself, while a good lube handles the sex moment. Both, not either.

The one to bin

Warming, tingling and flavoured lubes often contain glycerin, glycol, parabens or menthol-type ingredients that can irritate sensitive vulval and vaginal tissue and increase infection risk. If a lube says it will 'tingle' or 'heat up,' that is your cue to be cautious. Fun-sounding, but not friendly, particularly if you're sensitive.

The cheat sheet

Water-based for daily use, condoms and all toy materials. Silicone for shower, anal and long sessions (never with silicone toys). Oil-based for solo external play only. Hybrid if you want a versatile all-rounder. Vaginal moisturiser for ongoing dryness, alongside your regular lube.

Do this right and your vibrator will thank you. Your body will thank you. And you'll save your body, and your toys, from breaking down!
