Is it safe to clean pool tile with pressure washer?

While pressure washers are the most powerful tools, they have equal potential to damage the pool tiles if not exercised with caution. If you talk about the safety of pressure washing pool tiles, then it is safe, or rather, necessary, to pressure wash pool tile to maintain their aesthetic appeal. Pool tiles are usually made of either ceramic or porcelain and are a bit too fragile for pressure washing. However, it is crucial to understand that the pressure from the power washers should not exceed a maximum of 3000 PSI.

Starting with a lower PSI of about 2000 and gradually moving up to 2500 PSI is the best technique to handle pool tile cleaning. Most entry-level pressure washers do not possess adjustable pressure settings; therefore, you can achieve the same level of safety by using different nozzles.

To maintain safety while cleaning the pool tiles with a pressure washer, always start the pressure washer from a safer distance, moving the wand continuously. Prolonged targeting of the same point will cause the tile joints to break; hence, steady and constant movement is very important.

What causes a buildup of calcium on pool tile?

Calcium on pool tiles can occur due to several factors, including high levels of mineral-rich water, imbalanced pH and alkalinity, inadequate water circulation, and the interaction of pool chemicals. These deposits gradually accumulate, leaving unsightly stains that can diminish the beauty of your pool. Identifying and addressing these underlying causes is the key to removing calcium deposits from pool tile. We will address some of the main reasons here.

Hard Water

Hard water is one of the main causes of calcium deposits on pool tiles. Minerals are abundant in hard water, particularly calcium and magnesium. Hard minerals are left behind when pool water that contains those splashes onto your tiles and evaporates, and these minerals over time collect and form deposits.

High pH Levels

It’s important to keep the pH balance in your pool water in the proper range. Calcium and other minerals may precipitate out of the water and stick to the pool tiles when the pH level is too high (alkaline). This frequently happens as a result of poor pool water care.

Alkaline imbalance

Calcium deposits can develop as a result of an imbalance in the total alkalinity of pool water. A pool’s water may become overly saturated with calcium when alkalinity levels are too high, which can result in precipitation and scaling on the tiles.


High rates of evaporation can increase calcium accumulation in areas with hot, arid conditions. The concentration of minerals in evaporated pool water rises, increasing the possibility of calcium deposits on the tiles.

Calcium Deposits and Chlorine

The chemicals used to sanitize swimming pool water can also cause calcium deposits. Calcium scaling on swimming pool surfaces, particularly the tiles, can result from using too much chlorine or calcium-based chlorine solutions.

Insufficient Water Circulation

To avoid calcium deposits, water must be properly circulated and filtered. Minerals can accumulate on pool surfaces, especially the tiles, in stagnant water. Make sure that the circulation system in your pool is in working order.

High temperatures

Calcium deposits can form more quickly in water that is too hot, which is frequently a result of heated swimming pools or warm weather. The mineral precipitation on pool surfaces is made easier by the warmer water.

How to remove calcium from pool tile?

Calcium deposits can accumulate on pool tile over time, causing ugly white stains that not only detract from the pool’s aesthetic appeal but also jeopardize its general cleanliness and hygienic conditions. Fortunately, there are a number of efficient techniques you can use to remove these tenacious deposits from your pool tiles and bring back their natural sheen.

What will you need?

  • Steam pressure washer, preferably, or any pressure washer with adjustable PSI or a maximum of 2500 PSI.
  • Variety of wide spray Nozzles
  • Protective clothing and gear

1.      Select a pressure washer

Effective pool tile cleaning requires choosing the correct pressure washer. Think about your pool’s size and the intensity of the stains. Due to its increased power, a gas-powered pressure washer may be better suited if your pool is larger or there is significant calcium buildup. An efficient option for routine maintenance and smaller pools is an electric pressure washer. Make sure the pressure washer has the PSI (between 1500 and 2500) needed to clean pool tiles.

2.      Clean Up the Pool

It’s imperative to remove any debris or loose filth from the swimming pool before you start. To get rid of leaves, twigs, and other floating debris, use a pool skimmer or a net. Vacuum the pool bottom as well to remove any sediment or trash that has accumulated there. In order to prevent these impurities from being forced onto the tiles during cleaning, the pool must be cleared.

3.      Choose the Proper Pressure

Set the pressure washer’s settings appropriately. Start with a lower PSI and raise it gradually as necessary. Generally speaking, a PSI of 1500–2000 should be adequate for cleaning pool tile.
