The Thomas ProTex V is a specialized cleaning concentrate designed for vacuum cleaners with a washing mode, specifically formulated to remove stubborn stains like coffee, wine, and fruit juice from textile surfaces. This 1-liter solution works effectively on carpets and upholstery, offering a hypoallergenic formula that ensures safety during use. To achieve the best results, you apply the solution to the contaminated area and let it sit for 10 minutes before proceeding with a standard wet cleaning using either this product or the standard ProTex. Depending on how deep the stain is, you can mix between 50 and 100 ml of the concentrate per liter of water, finishing the process with a pure water rinse to leave your fabrics clean.
