How to use a poultice for stain removal

For the vast majority of stains, whether juice, leaves, oil or anything in between, you can generally remove them with ordinary household objects or, if need be, a commercial stain remover. But what happens if the stain is too deep, old, or stubborn to remove this way?

That’s when you need to use a poultice as part of your surface cleaning – a paste made from a mixture of liquid cleaner or chemical and a white absorbent material. Here, we’ll outline, step by step, how to use Dry-Treat’s HANAFINN Oxy-Klenza™ in order to get rid of a stain.

1. Get all the equipment ready

As always, you need to gather up all the necessary materials before you can start working. This means getting:

  • a container of Oxy-Klenza™
  • paper towels
  • builder’s tape
  • and plastic wrap

2. Make the poultice

Mix some Oxy-Klenza™ into a container of water to form a thick paste. Be careful not to use too much water. This should be a thick, dense paste, roughly the consistency of peanut butter.

3. Apply the poultice

Use a trowel, or a wooden or plastic spatula, to spread a liberal helping of the poultice onto the affected area. You’ll want to achieve a thickness of around a quarter- to a half-inch with the paste.

4. Cover the poultice

Dampen a paper towel and cover the poultice with it. The wording is crucial here – the towel should not be soaked. Then cover the towel entirely with plastic wrap, and tape down all four sides. The use of builder’s tape is crucial, or else you’ll need to do further stain removal later when lower-grade tape leaves a glue stain.

Now leave it for 24 hours. While you wait, the Oxy-Klenza™ and liquid will draw out the stain into the absorbent material.

5. Removing the poultice

After 24 hours pass, peel off the plastic and remove the paper towel, and use a plastic or rubber scraper to gently scrape off the plastic. Then use water to clean off anything remaining, using a cloth or paper towel to dry the surface.

6. Rinse and repeat?

Don’t panic if your particular stain is still there once you’ve removed the poultice. In some cases, you may have to repeat the procedure several times to thoroughly remove an especially difficult stain.

Also, remember to apply this procedure to a small, out-of-the-way area of the stone before cleaning in earnest. This way, you can test if the poultice will have any negative effects on the stone, such as discoloration.
