Quick answer: Replace a sex toy when the surface becomes sticky or tacky, when there are visible cracks or tears, when it develops a persistent odour that won't wash off, when the motor has noticeably weakened, or when the battery no longer holds a charge. For porous materials (TPE, jelly, PVC), consider replacing after 6-12 months of regular use. Quality silicone vibrators with proper care can last 2-5 years. Stainless steel and glass toys last indefinitely unless physically damaged.
Your toothbrush gets replaced every three months. Your mascara gets chucked after six. Your vibrator? Apparently that's supposed to last forever, because nobody ever talks about when to get rid of it. There's no expiry date printed on the side, no little symbol of a jar with "12M" on it. You're just expected to know. And most people don't.
The signs your toy needs replacing
Some of these are obvious. Some aren't. All of them mean the same thing: time for a new one.
The surface has gone tacky or sticky
This is the most common sign, especially with cheaper materials. You wash it, dry it, and it still feels like it's slightly grippy or tacky to the touch. That stickiness is the surface material breaking down. With TPE and jelly toys, it can happen within months. With silicone, it usually means the material quality wasn't great to begin with, or two silicone toys were stored touching each other (our favourite storage mistake, see the storage guide for how to avoid this).
Once a surface goes tacky, it's collecting and holding onto bacteria much more effectively than before. No amount of cleaning fixes degraded material.
The odour won't go away
Give it a proper wash with soap and warm water. Let it dry completely. Smell it again. If there's still a noticeable odour, musty, chemical, or just off, that's bacteria or mould that's gotten into the material's pores. With non-porous materials (silicone, steel, glass), a persistent smell after thorough cleaning is rare and usually means something has gone wrong with the manufacturing. With porous materials, it's inevitable over time.
Visible cracks, tears, or discolouration
Any physical damage to the surface is a bacteria highway. Cracks in silicone, tears in TPE, chips in hard plastic, all of these create crevices that can't be cleaned. Discolouration (especially yellowing or dark spots) can indicate material degradation or embedded mould. Either way, if you can see it, don't use it.
The motor sounds different
If your vibrator used to hum and now it rattles, grinds, or sounds like it's working considerably harder to achieve the same result, the motor is wearing out. A weakening motor doesn't just mean weaker vibrations, it can also mean the internal components are shifting, which can compromise the waterproof seal if it has one.
The battery won't hold a charge
Rechargeable lithium-ion batteries degrade over time. A toy that used to run for 90 minutes and now dies after 20 has a battery that's reaching the end of its life. Most rechargeable vibrators get somewhere between 300 and 500 full charge cycles before noticeable decline, which translates to roughly 2-4 years of regular use.
The buttons or controls are unreliable
If you have to press a button three times to get it to register, or the toy randomly changes patterns mid-use, the electronics are failing. This can also mean the waterproof seal has been compromised and moisture has gotten inside.
How long each material actually lasts
These are rough guides based on regular use (a few times a week) and proper cleaning and storage.
Medical-grade silicone (with motor): 2-5 years
The silicone itself lasts far longer than this. What limits the lifespan is the motor, the battery, and the charging port. If all of those still work well, there's no material reason to replace a quality silicone toy. Treat this as the lifespan of the electronics, not the material.
Medical-grade silicone (no motor): 5-10+ years
A pure silicone dildo with no electronic components and no physical damage can last a decade or more. It's a non-porous, chemically stable material. Just keep it clean and stored properly.
Stainless steel: basically forever
Short of dropping it off a balcony and denting it, stainless steel doesn't degrade. It doesn't become porous. It doesn't harbour bacteria. Clean it and it's good. Your grandchildren could inherit it (though they might prefer you didn't leave it to them).
Borosilicate glass: basically forever (unless you break it)
Same deal as steel. Glass doesn't degrade, doesn't absorb anything, and is fully sterilisable. Inspect it for chips before each use, a chipped glass toy should be retired immediately. But if it's intact, it's fine.
TPE/TPR: 6-12 months
Porous materials have the shortest usable lifespan. Even with good cleaning habits, the porous surface degrades and accumulates bacteria over time. If you're using a TPE toy regularly, plan to replace it within a year. If you notice any of the warning signs above, replace it sooner.
Jelly rubber/PVC: replace now (or use a condom)
If you're still using a jelly or PVC toy, it's already past its ideal lifespan from a material safety perspective. Use a condom over it as a barrier, and replace it with something non-porous when you can.
What about toys you rarely use?
A toy sitting in a drawer for two years unused doesn't get a free pass. Check it before you use it again. Material can still degrade from improper storage, temperature changes, or exposure to other materials. Give it the visual check (cracks, discolouration, stickiness), the smell check, and a test run before it goes anywhere near your body.
Also check for battery swelling in rechargeable toys that have been sitting uncharged for months. A visibly swollen battery is a safety hazard, dispose of the toy responsibly.
How to dispose of a sex toy
This is the part nobody thinks about until they're holding a vibrator over the bin and feeling weird about it. Here's the practical version.
-
Remove the battery if possible. Lithium-ion batteries should be taken to a battery recycling point, not thrown in general waste.
-
If the toy has no removable battery and you can't separate the electronic components, check your local council or undefined for e-waste disposal options. Most areas in the UK have e-waste collection points.
-
Non-electronic toys (silicone dildos, glass toys, steel plugs) can usually go in general waste. Silicone isn't widely recyclable yet, unfortunately.
-
If you're feeling self-conscious about it, wrap it in newspaper or put it in an opaque bag. The waste collection workers have seen everything, but do what makes you comfortable.
-
Some sex toy companies run recycling or trade-in programs. Worth a search before you toss.
The emotional part (yes, really)
This sounds silly until it applies to you. People get attached to their toys. Your first vibrator, the one that got you through a breakup, the one you bought on holiday, they carry memories. Replacing one can feel like a bigger deal than it logically should.
That's fine. Acknowledge it and then make the practical choice. A toy that's no longer safe to use isn't serving you well, no matter what it represents. The next one might become an even better companion.
What to look for in a replacement
When you're ready to shop for a new toy, here's the short list of what actually matters: body-safe materials (read our materials guide), a rechargeable battery with decent run time, waterproofing if you want easy cleaning, and a shape that suits how you actually use it.
VUSH makes every product with medical-grade silicone and lists exact specs on each page. If you're replacing something that's given up the ghost, our vibrator collection is a decent place to start. The Empress Tidal is a solid all-rounder, and the Muse is worth a look if you want internal and external at the same time.

FAQs
Is it safe to keep using a toy that still works but is several years old?
Depends on the material and condition. A three-year-old silicone vibrator that looks, feels, and smells fine? Perfectly safe. A two-year-old TPE toy that's gone slightly sticky? Time to go. Age alone isn't the deciding factor, material condition is.
Can I repair a vibrator with a dying motor?
Technically, some people do open up their toys and replace motors or batteries. Practically, this voids any warranty, compromises the waterproof seal, and requires soldering skills. For most people, it's not worth it. Buy a new one.
How do I know if my toy's battery is swollen?
The toy may feel slightly bloated, the seam might be separating, or it might no longer sit flat on a surface. If a rechargeable toy looks physically different from when you bought it (wider, raised seam, bulging), stop using it and dispose of it through e-waste recycling. Swollen lithium batteries can be a fire hazard.
Should I replace a toy after an infection?
If the toy is non-porous (silicone, steel, glass), a thorough sterilisation (boiling for motor-free toys, or soap and water for motorised ones) should be sufficient. If it's porous (TPE, jelly, PVC), replace it. Porous materials can harbour the infection-causing organisms even after cleaning.
My toy looks fine but it's been in a drawer for years. Do I need to replace it?
Not necessarily. Do the checks: look at the surface for stickiness or degradation, smell it, check the charge, and inspect for any physical damage. If it passes all of those, clean it thoroughly and it's likely fine. But if anything feels off, trust your instincts.
