How to antique brass with Clorox:
Clorox, as it is sold in the US is 5% sodium hypochlorite. It is used for cleaning and disinfection. It is very corrosive to mucous membranes such as eyes, nose and throat. If it does come in contact with skin or eyes, rinse throughly with water.
It will dull the brightness of brass and can be used to antique brass. The piece is typically soaked in a straight, undiluted solution. But it is difficult to control. It can corrode right through the brass piece. It can release toxic fumes that are hazardous. It must be handled with care and only used in a very well ventilated area. This chemical method is not recommended for antiquing brass as there are many other, safer methods available.
