NEVER rub!!!!! Rubbing will push the problem OUTward! You don't want that. Blot. Machines scrub the fibers in place..they don't push as rubbing with your hands will do. See the difference??
NEVER use resolve!!!!!! And Nature's Miracle just doesn't work! (Please know, I have over 9 years as a professional floor care specialist and I speciallized in stains and pet urine. NOBODY knows more about these things than I do. And yes, I toot my own horn. There is NO stain I cant get out of a carpet... (and if there is, I patch it. LOL) That is the worst thing you can do for any carpet. Resolve is a soap. It leaves a residue on the carpet and will get dirty quicker. Simple solution for almost all spills, spots, etc...: 1 quart water. 3 tbsp white vinnegar. 1 tsp DAWN. You can also use 2 tsp powder TIDE instead of the Dawn. This solution will work on just about anything. Spray on libberally and let set for 2-3 minutes. Then BLOT!
For pet urine, do this: (works best if you have either a TON of towels, or a wet/dry shop vac...or carpet extractor) locate the boundries of the spot. NOTE: that the spot UNDER the carpet is about 3-5 times the size of the spot on TOP of the carpet. If you have a 6 inch spot on top, get about a gallon to 2 gallons of water (1/8 cup powder tide and 1/8 cup white vinnegar per gallon). place towels around the spot about a foot outside in a ring. Place heavy books on these towels. Starting on the outside, near the towels, start pouring your solution. Pour from the outside, and work your way in to the initial spot. Know that the water is NOT going to be a problem as you may think. It just won't. Once you have all the water poured on, use your hands to 'knead' the water towards the center. Do this all around the area d then let it sit for 5 mintues. This is allowing the solution to absorb slightly into the sub floor. This is NOT a bad thing... Now, use your extractor to suck the water back up from the center. Press hard on it and extract for 10-15 seconds. Then move the extractor a few inches out and do again. Follow this around the circle. Once that is done, do it again. Now, cover the area with a couple towels doubled or trippled over. Place heavy books or objects on the towels. Leave them there for at least 12 hours. take up the towels and put down new ones doubled over. Place your books on them again and leave for another 12 hours. You are now all done. :)
If this sounds like a pain in the ass, you now know why I get $100-$150.00 for a pet spot. I can get rid of them in about 20 minutes. However, severely stained carpet where they go often can take a day or two to fix. And yes, it CAN be fixed without replacing the carpet. May replace the pad, and treat the subfloor with BIN, but it can be fixed. Something like that can run 300-600.00. I can even do orientals with amazing results..
