Cleaning with a pure water system

A pure water system is a specialised piece of equipment used for cleaning surfaces such as facades and windows. The system includes a water filter that removes minerals and impurities from regular tap water. The purified water is then applied to the surfaces being cleaned through a telescopic pole or other suitable equipment.

The key aspect of a pure water system lies in the removal of dissolved minerals, salts, and other contaminants from the water. Normal tap water often contains these substances, which can leave residue behind when the water evaporates on surfaces. Purified water, on the other hand, dries without any streaks because no minerals remain on the surface.

Pure water systems are popular for window and facade cleaning because they help achieve a crystal-clear, spotless finish without the need for chemical cleaning agents. These systems are frequently used in situations where particularly high cleaning quality is required, such as glass facades of office buildings or large window fronts.

Cleaning with pure water – specifically using demineralised or fully desalinated water – offers several advantages across various applications. Here are the most common benefits:

1. No residue

Pure water contains only minimal amounts of dissolved minerals and impurities, which means no residue is left behind on the cleaned surface when it dries.

2. Streak-free cleaning

Because pure water contains no minerals, it leaves no streaks when cleaning glass, windows, or other smooth surfaces, resulting in a perfectly clear and clean finish.

3. Gentle cleaning

Pure water is generally gentler on delicate surfaces, as it contains no aggressive chemicals that could potentially cause damage.

4. Environmentally friendly

Using pure water without chemical cleaning agents makes the cleaning process more environmentally friendly, as fewer harmful substances are released into the environment.

5. Prevention of limescale deposits

When cleaning surfaces that are prone to limescale build-up, such as in car washing, the use of pure water can help significantly reduce limescale deposits.

It is important to note that the effectiveness of cleaning with pure water depends on the type of contamination and the specific application. In some cases, specialist cleaning agents may be necessary, while in others pure water alone is perfectly sufficient.
