What's actually causing this
Carpet stains set permanently when liquid is rubbed in or allowed to dry. Different stains require different approaches: tannin-based stains (coffee, wine) need oxidizing cleaners, while protein stains (blood, urine) need enzyme-based treatments.

Step-by-step fix
-
1
Blot immediately
Use a clean white cloth to blot up as much liquid as possible. Work from the outside of the stain inward to avoid spreading. Press firmly but don't rub.
-
2
Apply cold water first
Pour a small amount of cold water on the stain and blot again. This dilutes the stain before applying any cleaner. Skip this step for pet urine — go straight to enzyme cleaner.

3
Treat coffee or wine stains
Mix 1 tablespoon dish soap + 1 tablespoon white vinegar + 2 cups cold water. Apply to the stain, blot, and repeat. For stubborn wine stains, try a 3% hydrogen peroxide solution — test in a hidden spot first.

Treat pet urine stains
Soak the area with an enzyme cleaner. Let it sit for at least 10 minutes before blotting. The enzymes break down the urine proteins that cause odor. One application may not be enough for old stains — repeat as needed.

5
Dry the area
Place a stack of white paper towels over the cleaned area and weigh them down with a heavy book. Leave for several hours. This wicks remaining moisture out of the carpet pad.
