The deep cleaning formula grabs dirt and other contaminants for a complete removal, while a specialized polymeric protectant is left behind. Interior surfaces, while not exposed to direct sunlight and weather, is one of the dirtiest and most commonly affected areas in a car. If not treated immediately, stains caused by dropped food, spilled soda, and other accidents will linger for the life of your car. Once set in, a deep cleaning with a high powered steamer is likely the only successful method of removal. Fortunately there are products that protect against this, and Optimum Carpet & Fabric Cleaner & Protectant is one of them. Optimum Carpet & Fabric Cleaner & Protectant is a two-in-product that does the work for you. Using effective and eco-friendly cleaners, each affected surface receives a deep cleaning. Unlike many other carpet and fabric cleaners, Optimum Carpet & Fabric Cleaner & Protectant is not harsh, and will not strip or bleach carpet fibers. As the product is gently lifting and removing stains, a strong layer of protection is being left behind. Think of a carnauba wax for your carpet. New stains and spills are less likely to hold, thanks to this new barrier. Optimum Carpet & Fabric Cleaner & Protectant is concentrated, increasing versatility and use. For most common stains, a dilution ratio of 1:3 will successfully treat the surface. However, for more stubborn stains, Optimum Carpet & Fabric Cleaner & Protectant can be used with no concentration for a higher level of stain removal. Some areas may need to be cleaned using a dedicated carpet extractor or steamer, but a pre-treatment with Optimum Carpet & Fabric Cleaner & Protectant speeds this process along. Optimum Carpet & Fabric Cleaner & Protectant will not leave behind greasy or oil residue. Just a clean and protected surface! Optimum Carpet & Fabric Cleaner & Protectant is safe to use on all interior fabrics. Directions for use:
