NEUTRALIZER is an acetic acid solution for neutralizing alkalinity in carpets and hard floors. When carpets have been extraction-cleaned with highly alkaline detergent, an alkaline residue may be left in the fibres. By rinsing with NEUTRALIZER, this residue is neutralized and the pH level is returned to an acceptable, neutral value. When porous hard floors are stripped with alkaline polish removers, a similar alkaline residue may be left in the floor’s surface. By rinsing with NEUTRALIZER in the rinse water, such residues are neutralized so they will not be able to spoil the floor sealer when it is applied to the floor. NEUTRALIZER is also a powerful browning treatment for removing cellulosic browning stains caused by overwetting, flooding or alkaline reactions in carpets or upholstery.
