Wood – How to remove hair dye stains on hardwood floor

If you use cleaners like Mop & Glo or Orange Glo on your floors than yes you will get a cloudy white film build up. The reason being is that these products have oils in them, that when used over and over again will build up and take away the shine. Answer

Yes it can be too much of a build-up or simply the type of product you are using. Go a hardwood dealership and ask them what you can do about this as there are special products for cleaning hardwood floors.

You'll probably want to rent a proper floor sander. A small random-orbit will take ages and you'll probably burn through most of its useful life.

The sander should come with a variety of paper grits. As with any woodworking project, start with the heaviest and transition to the finest. The final should be somewhere in the 100-120 grit range.

How far you need to go depends partly on the stain color--is it markedly different from the current color? Is it dark? Dark stain is more likely to compound if it's not completely removed. You'll see the old stain through the new as dark streaks or patches.

If you go the route of renting a sander, the work will be easy enough that you can get through the old stain without much effort, and you'll be confident of achieving a good result.
