The first time we used this, our hardwood floors looked truly spectacular. A month later, we applied again with good results, but then noticed that when we mopped, a white chalky film showed up. The floors looked the worst we had ever seen. We learned that this product contains a waxy chemical that creates the film and also traps hair and dirt. Removing it requires hours of scrubbing with ammonia... and that's the best case. Save yourself - AVOID THIS PRODUCT!!!!
