Removes Odour at the Source, Not Just the Smell - Specialised microbial cultures produce enzymes that break down the residue in urine, faeces and vomit that causes lingering smells. Because the residue is broken down rather than covered with fragrance, the odour does not return once the area dries, which also helps discourage dogs and cats from going back to the same spot. Built for Dog & Cat Urine Accidents - Tackles the jobs owners deal with most: puppy training accidents, cat pee outside the litter tray, older dogs, spraying and marking, plus vomit and faeces. Works as a urine destroyer and urine neutraliser on fresh accidents and on older, dried-in stains where the smell keeps coming back on warm or damp days. Carpets, Upholstery, Floors & Bedding - An enzyme carpet cleaner and stain remover for compatible carpets, rugs, sofas, mattresses, car seats, dog beds, crates, hard floors, skirting boards and grout lines. Particularly effective on soft furnishings, where urine soaks below the surface and ordinary cleaners only treat the top. Test on a hidden area first for colourfastness. Works Deep and Keeps Working as It Dries - Apply enough to reach as far as the urine did, into carpet underlay or sofa cushions, then leave to air dry. The enzymes keep breaking down residue throughout the drying time and the area does not need rinsing. Heavily soiled or long-standing areas may need a second application after a few days. Shake well before use. rusted Chemical Trade Store Quality - Manufactured, bottled and labelled in the UK by a Made in Britain member, with a trade-strength formula relied on by dog and cat owners, dog walkers, groomers, landlords and professional cleaners. Available in 1L, 2.5L and 5L, so the same enzyme cleaner covers a one-off accident or regular use across a busy multi-pet home.
