Can Pressure Washing Remove Calcium And Lime Deposits?

If you have a waterline in your residence, you probably have an idea of the problems posed by a lime scale buildup. In many cases, it seems that no matter what you try to do, the problem still remains.


Regularly washing with high-pressure nozzles will allow you to remove stains, and prevent dirt from accumulating on your hard surfaces. However, using a push broom to get rid of still water has traditionally been seen as the most effective way of reducing a build-up of mineral deposits.

Hard Water: The Guilty Party

Hard water refers to any water that comes with a high mineral content, e.g., iron, magnesium, and calcium. Currently, close to 85% of water in the U.S. is hard water, and it tends to create scale, which can erode the beauty of any hard surface.


White deposits will normally be left behind, once the hard water has evaporated. This is very common in areas with well waters, as well as rural regions. Initially, these minerals will look like salt or sugar, but with time, they will start to collect on your deck surface, or lower area of your pool.


As they continue to crystallize, they will gain the ability to absorb body oils and sun tan lotions. As time goes by, the crystals will darken, and your hard surface will start to look like it is dirty.


The only way to get rid of the deposits from hard water will be to carry out proper cleaning and maintenance. The water from your pool, hoses, and sprinklers may end-up creating standing water on your hard surfaces, e.g., pool decks, walkways, driveways, and patios. This will only act to worsen an already worse situation.

To prevent this, you can purchase a water softener, which will replace the minerals in your water, thereby eliminating hard water. However, if scale has already started developing on your hard surfaces, you will need to be careful when attempting to clean this scale.


Using chemicals that are too harsh will cause damage to the decorative finish. Commercial lime cleaners, coupled with bleach, can work wonders on unpainted and metallic surfaces, e.g., baths and kitchens.


However, they pose a danger to surfaces that are already painted, as they will normally remove the sealer. So, what should you do? Get a pressure washer, or hire a pressure washing service.

Can Pressure Washing Help In This Case?

Pressure washers are capable of getting rid of any kind of scale that may be on your hard surfaces. You should note that if you are to get the most out of your machine, you need to use the strongest power wash available. Additionally, ensure that your chosen pressure washer is capable of heating the washing water.


Pressure alone may be capable of cleaning different kinds of stains, but combining heat and the power of pressurized water makes it possible to clean all kinds of stains. The main reason why a pressure washer comes highly recommended for dealing with calcium and lime deposits is because the high pressure of the water will remove scale.


In addition to removing the scale, it will also help you to get rid of any dirt, chewing gum, mud, dust, grime, mold, and loose paint that may be on your hard surfaces. Homeowners can opt for the normal pressure washer instead of going for the industrial sized one.
