When you spot a spill, get to work quickly to prevent it from turning into a stain. In any of these scenarios, start by scraping away excess material, being careful not to rub in or spread the mess. Then blot the spot with paper towels and water before moving on to other remedies. Thinking about using a commercial spot remover? It's a good idea to test it out in an inconspicuous area of the carpet to make sure the cleaner doesn’t do more damage.
