Best wood stain remover?

Question

I have dark stain on my wood floors, and was wondering what was the best stain remover or best action to take to remove the stain from floors?

Answer 1

First, sand the wood down to its actual wood (remove protective coatings). After that the wood floor would probably look spotty with remaining stains. Apply bleach with a large sponge or mop. Don't overuse the bleach as it will harm the wood. Let it sit for few hours and mop with warm water. Repeat as necessary.

Answer 2

Well, it depends on what kind of top coat is on your floor - Polyurethane or Shellac.  

I had an antique table that I was refinishing and I ended up sanding the whole thing.  I had done 5 layers of stripper and still had to do more and my nose just couldn't take it anymore.  

Answer 3

The stain actually soaks into the wood itself, so you may have to sand them down a considerable amount. Even if they are real wood, this has a chance of seriously damaging them. This can not be done with laminate.
