Remove yellowed wax from floors using a mixture of ammonia and powdered dishwashing detergent. Mix the two cleaners in a gallon of water and apply with a sponge mop. The process requires a few minutes to soften the wax and a few more to scrub away the yellow stain.
- Check the detergent
Make sure the dishwashing detergent doesn't contain bleach. Mixing bleach and ammonia forms a gas that can damage the respiratory system.
- Mix the solution
Wear rubber gloves to protect your hands from the ammonia. Add 2 cups of ammonia and 1 cup of dishwasher detergent to 2 gallons of water. Mix to dissolve the detergent.
- Mop the floor
Wet the sponge mop with the solution, and flood the floor. Scrub gently. Use the abrasive scrub strip on the front of the mop to help loosen any resistant wax. Use the mop to soak up the solution. Move to the next section of flooring, and repeat until you finish the room.
- Dry with old towels
Use old towels to dry the floor and soak up any remaining solution from the floor. This solution may discolor the towels.
- Rinse away the old wax
Clean the mop and bucket. Fill the bucket with warm water, and use a damp mop to rinse the floor and remove the old wax. After the floor is dry, it is ready to re-coat with fresh wax.
