max you're likely to get from boots is 9%, whatever vol that is. more likely 3%.
even 3% will get rid of mould, it just takes a bit longer.
the stuff is great for degunging toothbrush heads and keeping the mould down, dilute as a mouthwash that has the added bonus of whitening yer teeth. sterilising tootbrushes and cleaning jewellery.
bells or care are two brands but it's not necessary to know that, just ask for hydrogen peroxide.
