I am new to the carpet cleaning business and I love it! I have sold carpet for 20 years now into cleaning and working for myself. I own a Mytee portable and Rotovac DHX and get amazing results. I would like the opinion from the old timers their preferences on pre sprays whether liquid or powder. Its so overwhelming all the different types. I understand the soils, stains, carpet fiber and such dictate alot, but in general which is preferred liquid or powder and why. I do love the Matrix Miracle for urine removal, I have had great success with that and using the water claw, with amazing results but for pre sprays im not too sure. I love this forum its great for newbies
