We have two children who left not a little dirt. The front seats looked bad from (leaking various fluids, yogurt, chocolate, etc.). It's amazing how well everything is really gone out. Just suck - Spray - brushing - abrubbeln with a rough terry cloth, repeat on stubborn stains. Looks like new and smells good. I would recommend this product without restrictions. Nevertheless, it is not cheap, it is still significantly cheaper than a professional cleaning.
