How to Descale a Carpet Cleaning Machine

Descaling means using a substance that can remove the layer of scales that accumulates when a metallic object has contact with hot water. Scaling is common in water heaters, kettles, and boilers.

Carpet cleaners can also accumulate scaling due to combined suction pressure and electricity that creates heat during use. The dirty water slightly heats up when the temperature transmits to the metal parts of a cleaner.

Descaling is important to maintain the cleaner's efficiency. The buildup of scales can interfere by weakening the cleaner's suction force.

  8. Gently pour the mixture through the funnel and into the container; cap it.
  9. Add a label "Descaler" on the container.

What is Hard Water?

Have you ever used the kitchen sink and the stainless countertop starts forming dry, white spots? Such white spots are the scaling effect of hard water. The scaling can also happen to your carpet cleaner.

Hard water results when residential tap water gets too many minerals, which are strong enough to leave scaling marks on almost any surface. Hard water is not recommended for drinking, but we often use it for cleaning and washing dishes and utensils.

Most homeowners use tap water, which is sometimes hard water, when they're cleaning with a carpet cleaner. The frequent, unconscious use of hard water is what mainly causes the scaling in the carpet cleaner.

This is the reason why the scaling builds up in the cleaner tank, hose, and other metallic surfaces.

You can ask or report the hard water to your local water provider. They can check the main water supply to resolve the abundant minerals on water they distribute to their consumers.
