Traffic Slam is a high concentrate pre-spray for carpets. This is a non-toxic free rinsing cleaner especially designed for the suspension and removal of heavy soils, grease, and soot build up. Traffic Slam is especially effective on heavily soiled Olefin. Traffic Slam has special emulsifiers that keep it fully active (as long as the carpet stays damp), even 1/2 hour before extraction. Excellent for removal of filter soil under drapes and doors.
