Such names are meaningless in any other country except the states? Hydrogen peroxide I think is hair bleach, but if I buy that its probably got other things in it to spoil it. What is a muriatic ? Citric acid is citrus which is orange and lemons, but whats a muriatic tree look like.... Sorry for giving eveyone a laugh but like I have said before, this is the UK, we only have maplins and the farm for milk and eggs.... --------------------------------- Hydrogen peroxide is H2O2, used as a bleach by hairdressers. High strength H2O2 might be difficult to obtain, suicide bombers often use the stuff to make their explosives. Muriatic acid is the old-fashioned name for hydrochloric acid (HCl). 30% HC1 is available from hardware stores and building suppliers, it is often used for cleaning drains and brickwork. Leon
