Make homemade floor wax remover by mixing ammonia and laundry or dish detergent in warm water, or by mixing white vinegar and warm water. The ammonia solution is best for vinyl and tile floors, while the vinegar solution works best on hardwood floors.
To remove the wax buildup from tile or vinyl floors, mix together 1/2 cup ammonia and 1 cup nonbleach laundry detergent with 1 gallon of warm water in a bucket. Another option is to mix 2 cups ammonia and 1 cup powdered dishwasher detergent with 2 gallons of hot water. Once the solution is mixed, apply it to the floor with a mop and scrub the floor with a scrub brush after the wax softens. After removing the wax, mop the floor with cold water and dry it with a rag.
For hardwood floors, mix together 1 cup white vinegar and 1 gallon warm water. Use a sponge to apply the solution to the hardwood floors. Once the wax softens, use a rag to wipe up the wax, repeating the process if necessary.
Floors that have wax buildup often look yellowish or darker than the original flooring. Sometimes people refinish the floors, rather than realizing that the wax is the cause of the problem.
