To perform tennis court cleaning efficiently and safely requires the correct equipment, and the required training on how to use the equipment in the correct manner without damaging the courts surface. This article is written to explain this process for you and also to show a few videos so that you have a good idea of what to expect when you hire a contractor for tennis court cleaning. The condition of the surface will obviously have an impact on how it will look after cleaning has taken place. If your paint is a bit tired and starting to thin then obviously the results will not look as good as when your courts surface is in very good condition.

Most people assume that the rotorwash/surface cleaner is a brush system because they can see the brush around the base of the rotorwash. The truth is much different to that. That’s why I made this video, to explain what is under the rotorwash, and how does it functions. I filmed it with the slo-mo function on my iPhone 7. If I turn slo-mo off, all you see is a blur because it spins at around 25 full revolutions per second.

Firstly I always apply pool chlorine on the courts surface as the first step because the rough texture of the court allows the mould to become very hard to remove with pressure cleaning alone. The chlorine breaks down the mould (I dont know how, but it works better than anything else on the market). This allows the contractor to use a much lower pressure to clean the court. Using a much lower pressure to clean the court is far better on the paint and greatly lowers any risk of damage to the courts surface.

This court has already had the chlorine applied, and you can see how quickly and easily the mould and dirt are removed. One of the biggest benefits of using a rotorwash is that the spinning arm underneath is always spinning at a fixed height from the surface. This means that the cleaning impact from the water is always the same, which results in such an even clean. Have you ever cleaned concrete with using only the wand/gun and you are left with all the zebra striping!! That’s because as you swing the gun from side to side, its swinging closer to the surface and then slightly further from the surface. Back and forth, back and forth. If the distance from the surface varies, so does the impact of the water, and that’s how you get cleaner bits and darker bits. This is not the case with the surface cleaner, so make sure your contractor is going to use a surface cleaner/rotorwash/whirlaway. There is 3 parts to the process. First apply the chlorine, then use the rotorwash to lift the mould/dirt from the courts surface, and the third part is the hose the dirty water off the court, otherwise it will dry and attach itself to the courts surface again, leaving it looking dirty.
I hope you have enjoyed this article but more importantly that you have learnt something helpful so that in future you can hire the right contractor for your tennis court cleaning.
