Hard Water Stains

7/23/2018 (Permalink)

Cleaning companies that have customers in hard water areas, which includes over 85% of the United States, sometime find it difficult to get rid of those nasty hard water stains on windows - especially large office or warehouses with large amounts of windows. The first step begins with understanding hard water and how it affects the buildings we clean, so our cleaning technicians can choose the best solutions to remove it.

Rain contains no minerals as it falls to earth. When it passes through the ground, it absorbs minerals, such as calcium and magnesium, which transforms it from “soft water” into “hard water.” Although hard water is not normally harmful to our health, it can wreak havoc on plumbing, fixtures, appliances, glass, showers, or pretty much anywhere water is used.

Once hard water evaporates, what's left behind are the minerals. These nasty mineral deposits cause crusty scale, stains, film, and mineral rings. This build up can become problematic and permanent if not addressed immediately.

Hard Water Cleaning Solutions for Removing Those Ugly Stains

Cleaning companies go directly to their cleaning chemical and tool inventory when confronted with hard water stains. Acidic and non-acidic, abrasive, natural or manufactured, there are a number of cleaners that have the ability to remove mineral deposits and scale. Make sure the cleaner you choose is the right one for the job, surface or fixture you plan on cleaning. Check the manufacturer's label or test the cleaner in an inconspicuous place first if you are not sure. The last thing you want to do is cause damage to your customers' building.

Usually removing mineral deposits such as calcium, magnesium, and iron requires an acidic product. Most hard water staining can be removed with a combination of the right cleaner, cleaning tool and of course, good old fashioned “elbow grease” for those really tough jobs.

Cleaning tools such as white scrubbing pads, scrub brushes, and steel wool, can be used with the cleaning chemical of your choice to assist in removing difficult deposits. Just remember that none of these tools should be used alone, as they can permanently scratch the surface of the window. Only use these tools when the surface of the window is wet with water or cleaning chemical.

We recommend starting your cleaning process with less harmful chemicals, tools, and methods first, then ramp it up to more aggressive methods should deposits persists. It may take several attempts to remove stubborn deposits.

Beware; strong acidic chemicals are very corrosive and damaging to certain types of surfaces such as stainless steel and chrome and will “eat” through them, so never attempt to use such chemicals without the proper training and testing.
