    What ho one and all,

    It was recently suggested to me, that 3% hydrogen peroxide is very good for cleaning toothbrushes and de-germing all sorts of things.

    Can't find any 3% so bought 6% and diluted to soak the tooth brushes.

    When i emptied the mug of cleaning solution into the wash basin, I could hear all kinds of gurgling coming from the trap; so presumable, the hydrogen peroxide was working on the gunk in the trap.

    Cleaning the trap is obviously a good thing, but is hydrogen peroxide a way to do so without dismantling the trap?
    I would live to 'clean' the almost horizontal drain pipes from the wash basin to the 4" downpipe, but it is almost impossible. Would a solution of HP do the trick?

    Not too often, it is strongly oxidising and will attack plastic and metal and rubber

    I wouldn’t use it to clean my toothbrush

    I was chemist in at uni

    Thank you for your comment. As I understand it, it is not so much 'clean' (although I used that word) but disinfect.

    Why is it considered a good cleansing product? And I will admit, that if it is soooo good, why is it not widely available?

    HP was the bleaching agent that 'suicide blondes' used, back in those hypocritical sexist-judgemental days, to 'dye by their own hand'. It's still used to disinfect wounds - ouch!

    Just curious, but what did you do to validate this suggestion before trying it out? Prior to putting rocket propellant [¹], however dilute, on my toothbrush I'd want to see multiple authoritative sources explaining why it's a good idea and also, if it is, why it isn't already common practice.

    [¹] OK, it's also a well-known disinfectant but, still, a little tongue-in-cheek hyperbole in the name of scepticism seems justified.

    The gurgling is probably it generating oxygen when it meets the gunk in the trap.

    It's one of the more eco bleaching agents ending up as water and oxygen (or oxidised stuff) but it's still a bleaching/oxidising agent so treat it with respect.
    1.5% hydrogen peroxide is commonly used as a mouthwash so I would have no issues with a 3% solution being used to clean a toothbrush. With regards to cleaning pipework I would also have no problems using that although I tend to use soda crystals and boiling water to remove gunk. If it is hair blocking them mechanical removal is the best method.

    Yes in the old days it was also used as a teeth whitener as well as a hair bleach. It's wideley used in the equine industry as a disinfectant.

    It's still currently used in such products as OTEX ear wax remover.

    Marvelous stuff - but be wary of buying lots of it, some nice chap from MI5 might be paying you a visit at early hundred hours one morning

    Coincidentally I just read an article this on how sealed honey will last indefinitely, and how it acts as a wound dressing. Apparently an enzyme in the bees stomach when injected into the homeycomb produces gluconic acid and hydrogen peroxide. It's the peroxide, as Tom says, that disinfects wounds and the hygroscopic action of the honey together with its acidity then draws out moisture borne infection.

    Its good stuff, Honey.:bigsmile:
