How to Remove Magna Chloride Carpet Stains

Magna, or magnesium, chloride is a common ingredient used to bind edible soy products, including tofu, and as a chemical de-icer. The product is effective for melting ice on your walkway but will wreak havoc on your indoor carpeting. Magnesium chloride de-icer effectively melts ice at below-zero temperatures but has a catastrophic effect on your carpeting, according to the Utah State University Cooperative Extension. Use the correct tools to salvage your magnesium chloride-stained carpets.

Things You'll Need

  • Shop vac or industrial vacuum
  • Water
  • Wet/dry vac or towels
  • 2 tbsp. liquid dish soap
  • Plastic scrub brush
  • 1/4 cup rubbing alcohol

      Remove the loose magnesium chloride de-icer, using a shop vac or industrial vacuum. Don't attempt to use your household vacuum to remove the de-icer; you could damage the machine. Continue to run the vacuum over the affected area until the loose de-icer is completely removed.

      Create a mixture of 2 tablespoons of liquid dish soap and 1/2 gallon of hot water. Stir the ingredients to create a sudsy mixture and pour it onto the affected carpeting. Work the mixture into the carpeting with a plastic scrub brush to prevent leaving a greasy buildup from the magna chloride.

      Create a mixture of 1 gallon of hot water and 1/4 cup of rubbing alcohol. Pour the mixture onto the affected carpet to remove the soapy mixture and any remaining de-icer.

      Dab at the carpet with a towel to remove excess liquid and allow it to dry completely before using.

Tips & Warnings

  • Place entrance mats at your doors to prevent tracking magnesium chloride de-icer into your home.
  • Avoid using magnesium chloride if temperatures are not below 6 degrees below zero outdoors. Instead, use sodium chloride products to prevent possible damage to indoor carpets and flooring.
