Firstly please let me know the texture of the floor,if it is hardwood floor,then using two household products and a bit of elbow grease, you can avoid having to refinish or replace your flooring.Nonwithstanding they are a little complicated,you might as well look through following instuctions:
Step 1:Mix equal parts of vegetable oil and white vinegar in a spay bottle; shake to combine.
Step 2:Spray a section of your floor and rub the solution in with a cotton towel. Use a clockwise motion to apply evenly over each section.
Step 3:Shake the solution every so often to keep the mixture from separating. Spray over the next section of your floor and rub in evenly, removing any excess with your cloth.
Step 4:Buff your floor using a buffer with a screen of 100 grit.
