Commercial carpet cleaning requires more than just a one trick pony carpet cleaner. The fact is most professional carpet cleaners use hot water extraction and that’s it. The problem is that quite often this is not the best method for commercial cleaning.
Commercial carpet is typically a tight looped carpet unlike longer residential piles. While this sort of carpet wears well for high traffic settings (no packing) it also is very susceptible to spots reappearing as well as color loss and dirty traffic lanes due to increased traffic. When cleaning commercial carpet some of the best methods are dry procedures.
These methods include bonneting, cymexing, and dry compound mixed in with hot water extraction. If your professional carpet cleaning company is unsure of these various methods, you might want to keep shopping.
