When cleaning windows, solar panels, frames, and facades, the same problem often arises: lime and mineral stains that remain after the water dries. These stains are particularly visible in sunny weather or with hard tap water.
With a resin cylinder and demineralized water, you can prevent this problem and work much more efficiently.
What exactly does a resin cylinder do?
A resin cylinder filters minerals and lime from tap water. Inside the cylinder is a "mixed bed" resin consisting of anion and cation particles. This resin binds lime, minerals, and other dissolved substances from the water.
This creates purer water that leaves virtually no residue when drying.
The result:
- fewer lime stains
- fewer streaks
- a cleaner end result
- less wiping required
Why do lime stains occur?
Normal tap water contains minerals such as:
- calcium
- magnesium
- lime
When water dries on glass or solar panels, these minerals are left behind as visible stains or residue.
This happens much less with filtered water.
Benefits of demineralized water and resin filters for home use
Streak-free results
One of the biggest advantages is that windows and solar panels dry much cleaner without streaks or lime residue.
Safe cleaning from the ground
In combination with a telescopic pole or Tuckerpole, you can work safely from the ground without a ladder.
Less maintenance for solar panels
Dirt, dust, and residue can reduce the efficiency of solar panels. With purified water, you can clean solar panels safely without harsh cleaning agents.
Fewer cleaning agents needed
Because the water itself is already purer, often less or no cleaning agent is needed.
Ideal for hard-to-reach places
Consider:
- skylights
- solar panels
- conservatories
- high window frames
- awnings
How long does a resin cylinder last?
That depends on:
- water quality
- the hardness of the tap water
- how intensively the cylinder is used
On average, a resin cylinder filters approximately 500 liters of tap water with an average water quality of approximately 300 ppm.
Over time, the resin can be easily replaced.
Why are more and more people choosing demineralized water?
Professional window cleaners have been working with demineralized and resin filter systems for years because it:
- works faster
- gives a better end result
- requires less post-treatment
Nowadays, these systems are also becoming increasingly popular for home use in combination with telescopic cleaning systems.
With a resin cylinder between the tap and the telescopic pole, you can easily create a professional cleaning solution for home use.
