Best ways to soft wash tennis courts

May 27, 2015

Benz Softwash supply softwash chemicals to the professional softwashing cleaning trade

Tennis courts abound in most towns and cities and are a profitable market for softwash contractors.

A tarmac tennis court needs regular maintenance to keep it both looking good and safe to play on. Biological growths such as algae and moss can make the playing surface dangerously slippery. And it’s simply not much fun playing on a dirty court that's been colonised by various forms of biological growths.

When to use Benz Bio Cleanze

Algae often appear after a prolonged wet spell but the whole court may not need to be treated. You'll likely find the borders and shady areas require more frequent treatment than the rest of the court.

How to use Bio Cleanze

The most effective approach is to scrape the worst of the biological growth off first. Then spray using professional soft washing equipment, or if that is not available a watering can with a fine rose can do a reasonable job.

Thick and heavy moss growth will need plenty of mix to ensure it gets fully soaked. Applying twice on a first clean, to ensure saturation, is often a good idea.

The dilution rate on a first clean may need to be 20-30:1, while for maintenance cleans 40-50:1 is usually sufficient. The actual dilution rate will vary according to the degree of colonisation and the local environment.

Quick tip: If children are to use the court keep the dilution rate to a max of 40:1.

 

How to get the fastest results from soft washing

If the customer wants the court to look immaculate very quickly – perhaps because of an approaching tournament – use a light power / pressure wash before treating with Bio Cleanze.

Manually scraping the worst of the moss from the surface prior to treating may also be indicated.

Alternatively, use Benz Lightning Cleanze at 5-10:1, in conjunction with light power / pressure washing, for the fastest possible results.

Bear in mind that LIghtning Cleanze can lighten the colour of tarmac, so treat a test patch first and get your customer's agreement that it is acceptable before treating the entire court.

If Lightning Cleanze is applied at 5:1 the lightening effect may be considerable, so consulting with your customer to ensure they are happy to go ahead is essential.

Quick tip: Some customers prefer the lighter grey colour of tarmac after treating with Lightning Cleanze. Some do not. And many do not mind either way. It's simply a matter of personal preference.

 

How to soft wash acrylic painted tennis courts

Acrylic painted tennis courts are best treated differently.

We suggest first treating the entire surface with Bio Cleanze at 50:1, which will kill the biofilm. Leave the court for a minimum of one week following treatment to let the biofilm start to break down.

Then a treatment of Lightning Cleanze at 5-10:1, followed by a light pressure wash to rinse and remove any surface debris, will leave the court clean and the players – and of course your customer – very happy.

You will find this to be a far easier process that uses a smaller quantity of chemical and water than if you had not pre-treated with Bio Cleanze.

You could of course use Lightning Cleanze as the first treatment if time is particularly critical. But this will mean using more Lightning Cleanze ( at 4-5:1 dilution). Also, more aggressive pressure washing may be required, which could harm the acrylic coating.

 

Whichever method you use, once clean keep the court looking great all year with an ongoing "Clean & Maintain" treatment.

Once a year should be sufficient for a general whole court maintenance treatment, with localised treatments in shaded or other areas susceptible to recolonisation as and when needed or every 6 months or so.

Benz Softwash Bio Cleanze DDAC biocide & Benz Softwash Lightning Cleanze SH sodium hypochlorite biocide

Legal statement about using biodegradable Bio Cleanze to kill and control moss: For many years the active ingredient in Bio Cleanze (DDAC) was used to kill and control moss.

But as from June 2015 the politicians and bureaucrats decreed that moss is to be considered a “plant” and therefore comes under a different set of labelling regulations.

As such the law now states that only manufacturers of expensive herbicides (aka “weedkillers”), which are often quite unhealthy for humans and for our environment as a whole, can claim to kill and control moss.

From June 2015 no biocide manufacturer can state that a biocide such as Benz Bio Cleanze kills and controls moss, even though it was previously used to kill and control moss for many years.
