I recently attempted to clean a glycol stain. Not a job I usually take but this is a fairly new customer & the last two times I turned him down for one reason or another any way he had a glycol leak on a plush green carpet about 20 sf total. I extracted as mush as I could with the water claw then rinsed with my solution & repeated a couple of times. There was still some residue so I sprayed a fine mist of dry solvent worked it in with my brush then rinsed & extracted again. Went over it with a towel a couple of times & called it good. Now a couple weeks later he called & asked if I could come by & treat it again because there is still a slimy feeling on top of the carpet. I’m thinking it wicked back & if that’s the case would it be best to remove the pad & seal the floor? Also will I ever be able to get the glycol out of that thick carpet?
