The term 'steam cleaning' is often used interchangeably with hot-water extraction. When done by trained professionals, the water is heated to the optimal level to loosen soils without harming the carpet's integrity. Problems typically arise from the misuse of machines that apply too much water or fail to extract it, leading to saturation. Excess water can permeate the carpet backing, causing issues with adhesives, carpet shrinkage, or even the growth of bacteria and mold within the pad or subfloor.
