Having the floors cleaned properly is a massive thing in our home. We have a granite floor in one of the bathrooms, and parquet flooring throughout other parts of the place, and both need to be treated differently, but with equal respect. I find that one of the best ways to ensure that you can have these things done properly is to get a company like Brixton Cleaning in, which is who I use. They know what cleaning chemicals and techniques are best for the floor to get rid of the dirt, without scratching or stripping the finish.
