BISSELL Wash and Protect Professional formula contains double the quantity of non-volatile cleaning agents for the best possible results. Its dual action formula deep cleans and protects in one easy step, leaving your carpet fresh and revitalised. The inclusion of Scotchgard helps to protect your carpet from future stains and soiling, making it easier to vacuum and clean in the future. Wash and Protect is 2 times concentrated for ease of use and storage. This 1.5L bottle is equivalent to 3 litres of un-concentrated formula, but because it is concentrated, it's easier to carry, store, and the reduced use of plastics is kinder to the environment. This Wash and Protect carpet cleaning solution is suitable for all full-size carpet cleaners, washers and 3-in-1 machines and is safe for use on wool, nylon and acrylic carpets.
