Treating stains
Removing Grease Stains
Try explaining this one to guests. Not sexy.
If fresh, use kitty litter to absorb as much of the grease/oil as possible, then vacuum.
Next, use Britex Spotter on the stain. Britex Spotter is specially formulated to remove most carpet and upholstery stains caused by oil.
Just follow the instructions on the back of the label.
