My lacquered floor was installed 6 years ago. The only cleaning product I purchased previously was an off the supermarket shelf product. As a result of this unintended neglect my floor was very stained and in poor condition. Much improvement was evident after using this product but it is too late for proper prevention and maintenance. If only this product was advertised on TV or in home magazines, or promoted by flooring suppliers. If I had known how to care for my floors I would have done so. I am happy with the product but extremely unhappy that there was no publicised consumer information. So many people have hardwood floors and need to know about this.
