Sometimes the surface material or its finish may be sensitive to certain pH levels and damage could occur. Wool is damaged by high alkalinity and should be cleaned with a pH no higher than 8. Some dyes are adversely affected by higher pH, so neutral or slightly acidic cleaning agents are used to help stabilize the dye, even though some cleaning ability may be sacrificed. There are also times where the pH is varied to counteract the pH of previous solutions that could cause damage. High alkalinity may cause yellowing, bleaching, or other fiber damage.
High acidity dissolves many fibers and dyes.
After determining the pH of the soil a technician should determine the pH of the surface material to choose the correct cleaning solution. It is necessary to pre-test in an inconspicuous spot to be sure the desired results are achieved. Then and only then can a technician proceed. Many laminate flooring manufacturers advertise the durable finishes, wear resistance and easy cleaning. Deep scratches, chips or burns may be difficult to repair because the laminate may not be suitable for refinishing.
