Scrape any stain material off the carpet with the dull side of a table knife. Wipe the table knife on a paper towel and continue until the substance is completely removed.
Lay two or three paper towels over the stained carpet. Press down to absorb any liquid in the fibers. Repeat to remove as much moisture as possible.
Spray the remaining carpet stain with the washer fluid to moisten the fibers.
Blot the carpet with a clean, dry cloth to lift the washer fluid and stain. Repeat Steps 3 and 4 until the remaining stain is removed.
Allow the carpet to air-dry completely.
