Caustic soda (sodium hydroxide) solution used as the first part of the "AB" wood bleaching system. This is applied to the timber initially and left to soak in. The "B" bleach is then applied over this. A chemical reaction takes place producing free oxygen which acts as a very powerful bleaching agent.
This system will bleach nearly all timbers down to an off white colour.
Water and methylated spirit soluble oxalic acid crystals used extensively as a wood bleacher.
Will lighten or eliminate water, ink, alcohol and mildew stains on new or stripped timber. Will also lighten the wood itself in varying degrees.
Poisonous - keep out of reach of children.
*Wear suitable gloves and eye protection when handling this product.
