Centrachlor Red Label is industrial strength bleach (sodium hypochlorite 12%). It is very effective at cleaning and destroying bacteria, algae, moulds and fungi. It is safe to use for cleaning applications on concrete but care must be taken and PPE should be worn such protective glasses/goggles and chemical resistance gloves.
If being used for concrete cleaning it is best to wet the surface with water first. Dilute the Centrachlor Red Label 1 part with 3 parts water and apply over surface. Leave for 30-60mins then wash off. Do not allow solution to dry in. If there is heavy soiling, agitate surface with a brush to help clean. Keep pets and children away from treated area until it has been thoroughly rinsed.
