Nail Varnish
Guidance
Alias
nail polish
Nail and gel polish are not recyclable, so the best thing to do is use them up.
If you do have unwanted nail varnish, it is highly flammable so please do not put in your household rubbish bin. You can dispose of it for free through the City of London hazardous waste service (opens in a new window). However, this would need to be part of a bigger booking with other household chemicals like oil-based paint or weed-killer.
