Many carpet cleaning companies use commercial carpet cleaning solutions that contain perchloroethylene, the infamous dry cleaning additive which can cause dizziness, fatigue, nausea, kidney and liver damage, and naphthalene, which is both a neurotoxic and a possible human carcinogen, according to the Environmental Protection Agency. Naphthalene and other petroleum distillates can also attract more stains, since their oily residue is never completely washed away. Since we are removing greasy soils, heavy metals and contamination from human and animal bodies with the sanitizing effect of pure super heated water, professional cleaning leaves carpet and upholstery in the healthiest state possible. Pretreatments are used, but we are careful to select nontoxic products that are biodegradable. Certified Green cleaning products are available for additional charges, but we at Accuclean feel that these charges are unnecessary. Also, waste water is always disposed of responsibly and within the law.
