x3 on the Oxyclean. I mixed 1/2 (about 1 Tbsp.) scoop in a quart hand spray bottle and mixed it well. Be sure the area is dry before you spray it as it will spread the stain if it is wet. I used a shop vac to dry the ceiling initially. I also used a fan to blow air thru the MH to dry things out. Don't saturate the area, but spray it lightly and let it dry thoroughly. Repeat as necessary. Don't rub the fabric as it will loose it's definition of the nap. I hope this helps.
