Emerald Deruster PH 7 is an aqueous neutral solution designed to be used as a soak
immersion to remove all the rust from steel and iron. The product is used at full strength
with soak times of as quick as 15 minutes to 24 hours in extreme cases at room
temperature. Faster effectiveness may be achieved through heating. Since Emerald
Deruster PH 7 is neutral no special equipment is required although safety glasses and
gloves should be worn. The product can be used over and over until it stops working. On
average, a gallon will de-rust up to 400 pounds of light rusted steel.
