Qualify the rug with your customer as urine damage may cause bleeding during immersion. Also, staining from urine often is permanent on natural fibers. First dust the rug.
If the rug is extremely urine damaged spray rug front and back with At Last and let sit for 1/2 hour.
Put the rug in immersion pit and saturate with water. Mix one pint of Urine Lock and one pint of Skunk Odor Control in 5 gallons of water for a 9×12 piled rug, adjust the amount of product based on rug size. Pour 1/3 of the diluted product on the rug back and shampoo. Then turn the rug over and pour the balance on the rug pile and shampoo.
Add water until the rug is covered with 2 to 3 inches – then roll the face of the rug using the MasterBlend Rug Roller.
Let rug soak for 3 to 4 hours rolling the rug each hour.
Drain water from the pit and flush with fresh water while rolling rug. Continue until the rinse water is clear. Then wash the rug with your normal process.
Allow rug to dry – if dye bleed is a concern dry the rug flat.
