What does the washBOX® do

washBOX® changes the shape of the lime crystals into microscopic smooth crystal sticks by environmentally friendly, physical treatment.

These new shaped crystals can no longer stick together and do not form hard lime deposits. These reshaped crystals can no longer adhere and form hard limescale deposits.
The water is softer, the saponification is stronger, so the Detergents can be reduced by up to 50%.

WashBOX ® is the portable and ecological water softener for you.
Wash your Bike, Boat, Car, Caravan, Classic or Yacht with it – no more streaks and polishing – thanks to our mobile anti scale system!

No more excessive polishing of your car after the wash. Streak free and ready to ride, soft water saves you time and money.


Calcareous water is a problem almost everywhere. washBOX® changes the surface tension of the water and the flow behavior. It drains more easily. Soft water helps to wash streak-free without much polishing.

How do I use the washBOX® ?

How do I use the washBOX® ?
1) Water connection:
The effect of washBOX is the better the longer the water hose is after the washBOX®, before the box, the length does not matter.
2) Electrical connection: 220Volt

And then you are set:
=> the water is softer, the saponification is stronger, therefore the detergents can be reduced up to 50%.

Filling up the tank of a yacht with washBOX®. What should you consider?

You can do this if you use up the water within 2 days. Why?

washBOX® changes the crystals of the limescale into a new form that no longer has any adhesive properties. Limescale can therefore no longer form or stick to surfaces.
However, if the tank of a yacht is filled with washBOX® and the water is not used up within 2 – 8 days, the lime crystals form back into the old form. This means that the lime precipitates again.

What to do if the source water is dirty?

If you have water which is full of sediments or not really cean, we recommend to use a water filter.
=> remove existing lime desposits first.
=> if the water is very dirty, a sediment pre-filter should be used like our new Pre-filters

Pressure reducer for high pressure water

Please note the following: If the pressure reducer is used, this is the water inlet of the washBOX®. The hose supplying the water must be connected to the pressure reducer.

The pressure reducer is engraved with an arrow indicating the direction of flow. The pressure reducer must therefore be connected in this direction.

Is there a the warranty?

Yes. The washBOX® has a warranty of 2 years. It is sealed for this warranty period.
Damage caused by improper or violent use is NOT covered by the warranty.
