An advanced formula that efficiently tackles tough oily and greasy soils prior to extraction rinsing and is a Woolsafe approved maintenance product for wool carpets and rugs. Ideal for use in domestic and commercial environments. Follow up pre-spraying with extraction cleaning using B109 Fibre & Fabric Rinse or S781 Liquid Woolsafe.
