Denatured Alcohol on Untreated Floors

Denatured alcohol is ethanol with several added properties which make it unsuitable for human consumption. However, it is a great cleaning agent for floors with no protective finish. Denatured alcohol can dissolve stains and grease, leaving your untreated floors clean and spotless.

To clean carpet pad stains on an untreated hardwood floor, you need:

  • A microfiber cloth
  • Soft scrapper or scrub
  • Denatured alcohol

Let it sit for 5 to 10 minutes before scrubbing off the stains using the blunt or plastic scraper or soft scrub. The stains will come off easily without damaging your hardwood finish. Then, leave the spot to air dry.

For deep-set stains, sometimes more intensive treatments like sanding may be necessary, as detailed in how to clean old wood floors without refinishing.

Mineral spirit or mineral turpentine is a common organic solvent often used as a paint thinner.

You will have to be careful not to ruin the finishing. Then use a microfiber cloth to wipe off the remaining residue. Leave the spot to air dry.

Best Cleaning Agent for Sticky Carpet Pad Stains

Carpet padding stains are hard to remove due to the use of powerful adhesive during installation or heavy foot traffic over a long period. You can prepare the best cleaning solution to remove these marks by mixing one part of ammonia into one part of hot water.

Which Cleaner to Use on the Hardwood Floor?

The finish on your hardwood floor determines which cleaner you should use. You can figure out the type of finish with a water drop test. Place a drop of water on the hardwood floor to perform this test. If the droplet gets absorbed, the finish is worn out. If it stays beaded, the finish is strong.

Water-based cleansers are unsuitable for a weak finish as water will get absorbed in the wood and damage your floor.

Sometimes, a mixture of vinegar and water can be effective for certain types of stains, as also recommended for various cleaning situations in how to clean and maintain laminate floors best practices and products.
