How to softwash slipways for launching boats
A customer asked us about the best way to softwash a boat slipway.
The first question we asked was, "Does the slipway you've been asked to clean lead into freshwater or saltwater?"
The surfactant in both products is biodegradable and after activation the sodium hypochlorite component in the formula breaks down into ordinary salt and water.
We recommend a light jet washing first with clean water (nothing added) to clear away the worst of the organic material that slipways inevitably accumulate.
Clearing loose matter away through a light jet washing allows the softwash cleaning products to act more effectively on the cause of the infestation – the biological growths such as algae and lichen.
Quick tip: Treat the slipway at low-tide, which will ensure the products can work most effectively for the longest time on the maximum surface area – and will give you the maximum time to spray, brush and rinse.
If the slipway leads into freshwater then don't use Lightning Cleanze or Tornado Cleanze as the run-off could harm the aquatic life.
For a freshwater slipway we suggest applying Benz Bio Cleanze at 20-50:1 (depending on the degree of colonistion by algae, lichen, and other organic growths) after a light jet washing to remove loose matter.
Quick tip: Applying two treatments consecutively at 40-50:1 is also a valid approach, especially if the growths are particularly thick and it's been a long time since the slipway was softwash cleaned.
Spray Bio Cleanze very carefully, using a Benz 6.5 nozzle, on a dry and reasonably wind-free day, keeping the chemical on the slipway, and avoiding overspray into the water.
Bio Cleanze is bio-degradable and by working in a careful and responsible way, the harbour master, boat owners and our environment will be happy with the completed softwashing of the slipway.
We hope this information is helpful.

How can you learn the practical how-to of soft washing quickly, easily and simply – without wasting several years "re-inventing the wheel" – learning through arduous trial and error – when you could have been up and running in a few weeks?
And earning well-deserved profits from a highly efficient soft washing business.
Then there is the thousands of pounds/euros that the unwary, knowing no better, can waste on expensive, and often unnecessary or inappropriate, softwash equipment. We're sure you don't want to be like them.

In this ongoing soft washing video series Ben explains why and how he uses various types of softwash equipment.
What soft washing equipment you choose to build or purchase depends on several factors: for example the number of employees you have and the type of properties you soft wash.

That's a reasonable question.
You could jet wash a roof and then treat with Bio Cleanze.
But why would you?
