There can be quite a bit of contaminant sticking to your rug fibers and the base. Vacuuming alone will not expel them, so cleaning them eventually is inevitable. When hiring a company, you may wonder what cleaners are being used to clean your area rugs. Optical Brighteners, dyes, synthetic fragrances, petrochemical solvents, carcinogens, and are common in many rug cleaning chemicals. Rug cleaning chemicals used take a while to biodegrade. They can accumulate over time and react with new chemistry and sometimes biodegrade to more hazardous compounds. This contributes to a toxic household environment (Where children, pets and home occupants crawl, lie and breathe the leftover residues.). Some local companies typically purchase a substantial amount of raw crude rug cleaning chemicals, for discount prices, and use them to clean your area rug. These cleaners traditionally have high ph levels and can instantly break down the organic oils in your area rug!
