This product is effective on both water and petroleum based spots and spills.
Most competitive spot removers contain ingredients that require the carpet to be water rinsed or extracted after spot or stain removal. If they are not rinsed the residue will immediately begin to attract soil.
Safeguard General Spotter should not be rinsed so that encapsulation of the spot residue can be vacuumed away and the soil repelling properties will continue to work.
