I looked at a liquor store carpet to clean this morning and I would appreciate any suggestions. My plan is to use BioPro 10K, spiked with groutmaster, and to heavy scrub with a 175 machine and a nylon brush. Most of the spills have been there awhile and are a variety of different liquors, plus some salt lines from winter. How would you guys recommended treating the spots (there are a lot of them) and is there something I should do differently with my process? There is about 4,000 sq ft of carpet to clean, how would you price a job this size? And any extra tips of removing the salt lines off the rug? I have only cleaned a couple of rugs like that with such deep grooves and I have had a hard time removing the salt line on them. Thank you for any help.
