In order for our product to work, two things need to happen:
1) the product must come in contact with the urine. The urine may be deep into the carpet, into the pad, and maybe even the sub-floor, so apply enough so it gets down deep.
2) the product must be given time to work.
First, test an inconspicuous area for color fastness before using. Apply the product to the trouble area and leave it for 30 minutes. Then put a towel over the treated area with a weighted object and leave it overnight. Once dried, vacuum and inspect treated area. Odor should be gone. If not, repeat procedure.
