De-Brown No 2 is an acidic solution for removing browning stains caused by wicking from the backing of coloured carpets. May also be successful in removing tanning stains such as tea and coffee.
Directions for use:
Apply a light mist to the affected area and massage in using a clean sponge.
An immediate result may not be evident until the carpet is fully dry, ie overnight.
A second or even third application may be necessary.
