Christmas means much cheer is going around! If something lands on your carpet it is better to do nothing rather than use the wrong chemistry. It may set the stain. It all has to do with pH. Most carpet is engineered to resist acid stuff. If you change it to alkaline, you probably will set it unless you remove it. There is no urgency. Relax. Call if you have questions. Red Christmas tree blankets are infamous for leaving red stains when you take the tree down. Merry Christmas! DRYEX (360-280-2171 - m & txt)
