For large spills use a wet/dry vacuum (or Shop-Vac) to extract the bulk of the spill. If just a small amount was spilled, blot with a white towel to remove as much of the stain as possible, then neutralize with a solution of 1/3 cup of white vinegar, 2/3 cup of water. Saturate spot, using a spray bottle and blot to remove excess moisture. After neutralizing, go to step 3 of general procedure. If any discoloration persists after area is dry, try misting with undiluted 3% Hydrogen Peroxide ( $1.99 brown bottle from the drug store) once a day for a few days to see if the stain lightens.
