Wet it thoroughly & cover with salt or clay cat litter. Let stand. Vacuum up salt/cat litter, repeat if necessary. If any staining remains, try Oxy Clean or hydrogen peroxide (test on an inconspicuous area of carpet first). Use at your own risk. George E. Henry, CRA, PBT Wheaton Eye Clinic, Ltd. 2015 N.
