    Just have a few small parts and want to strip down to bronze and polish.
    Some kind of acid?

    Thanks all

    Send it to me, I'll have my ex-wife hold it next to her heart for a few minutes, which will be more then enough.

    I was going to suggest sending it to a Keno Girl in Reno ... but that only works for trailer hitch balls ... ;)

    I once searched for an answer to this. I came across a forum where some guys were talking about how easy it is. One guy said he used normall houselod bleach. The other guy who didnt want to be out of the picture said he just soaks the part in washing up liquid???????

    This was a septic forum by the way. It does'nt work. No i didnt try it.

    Thats interesting. What and where could i find Muratic acid ? I mean is it in a domestic fluid that could do the job and be bought from a supermarket. I live on an Island off Malaysia. lemon juice, viniger, battery acid, tile cleaner. Oxalic?

    Damned if I know - the last time I bought muriatic acid it was from a chemical supplier who sold me carwash soaps and waxes and hydraulic fluid. And that was over twenty years ago.

    Hardware store maybe, or auto supply store?

    Thinking about it maybe its more of an electrolite than an acid, seeing as though heavy current is needed to displace the chrome. (Opposite to the chroming in the first place.) Dont they use copper sulphate solution, or battery acid would do then?????

    I dont know im guessing -just trying to find a recognisable substitute.

    Spirits of salts
    Hydrochloric acid
    Muriatic acid

    All the same thing. Very common industrial chemical at around 30% often used as a cleaner at lower dilutions .

    cheers

    muriatic acid

    It is used in swimming pool cleaning so those suppliers should have it.

    Mas,

    No joke about the add acid to water part. Adding water to acid (or to caustic) will cause an immediate violent reaction. Severe burns and possible permanent eye damage if you're lucky; blindness and/or lung damage if you're not. And yes, do it outside, because there will be fumes even when done properly, and have rubber gloves and eye protection.

    Good way to remember is you want to add a little bit of the nasty stuff to a large amount of water to stay safe.

    Mmmm there must be a better way of remembering that.

    Damn I can remember it now and I am thinking about it.

    Would battery acid work? thats how you buy batteries here,--dry, and they give you a bottle of mix to put in yourself, imagine that in Europe!!

    Anyway --say I got this set up with a bucket . I assume that swoping the polarity will mean I got my own chroming plant.They gold plate jewellry at the side of the road in Bangkok using old scrap gold ,but what can I use to chrome with? an old car door handle?
