The finish on hardwood flooring is neither fragile nor indestructible. Hardwood floors must be cleaned properly using the correct solvent level to protect their beauty and fine finish. Some of us (ahem) have had to learn this truth the hard way.
Even though you can’t damage hardwood floors by walking on them, all wood is susceptible to stains. And you can dull a beautiful hardwood floor by cleaning it with the wrong solvent. Used properly, hydrogen peroxide is not one of the damaging solvents. It is, in fact, a very effective stain remover and a reliable cleaner for hardwood flooring.
