Clean the plexiglass


Plexiglas finds numerous applications inside as well as outside. Accordingly, Plexiglas can also pollute differently. Since Plexiglas is a thermoplastic material, the special features must also be taken into consideration when cleaning. Below we give you extensive information on how to optimally and professionally clean Plexiglas.

The use of Plexiglas

Plexiglas is used differently. It can be used outdoors as well as indoors. However, this results in different stresses. Thus Plexiglas is a very dense and homogeneous material.

That is, the surface of plexiglass provides little support for dirt. In the outdoor area is therefore already a certain basic cleaning by rain, snow and wind. In the interior Plexiglas is usually only wiped off.

Acrylic glass charges electrostatically

Like other plastics, however, acrylic glass can also become electrostatically charged. This is then explicitly important when cleaning Plexiglas indoors. The cleaning agent is therefore wiped without it then should be dried. Again, an electrostatic charge can occur.

Not every cleaning agent is suitable for Plexiglas

But before you use a cleaner, you must remember that PMMA plastics are not compatible with all substances:

  • organic substance
  • benzene
  • ethanol
  • alcohol
  • benzene-containing gasoline
  • numerous dilutions of synthetic resin products

On the other hand, however, is the compatibility of other substances:

  • light to medium lyes
  • acid resistance
  • Fats, oils

The cleaning technique depends on the degree of contamination

This in turn means you can use traditional running-based household cleaners (soap, dish soap) to clean Plexiglas. After all these properties, you now agree the cleaning of the Plexiglas on the possibilities and the degree of pollution:

  • light soiling, inside (dust): antistatic duster
  • Medium soiling (greasy fingerprints): Household cleaner based on lye, diluted if necessary
  • heavy soiling (paints, varnishes): water-diluted brush cleaner
  • Attacked Plexiglas surface (thinner, varnish): Polish Plexiglas

It is always important indoors that you should not dry the Plexiglas after cleaning. Otherwise, there is always the risk of electrostatic charging.

Clean the plexiglass outdoors

Outdoor drying is usually not necessary anyway, but other cleaning techniques can be chosen here. It is recommended to use a pressure washer (steam jet). You can add a suitable cleaning agent to the spray water.

Differences in plexiglass

In terms of temperature, you have to be careful in spite of the good, heat-resistant properties. For example, there are Plexiglas from Evonik, which differs in the manufacturing process:

  • extruded Plexiglas (Plexiglas XT)
  • cast Plexiglas (Plexiglas GS)

Adjust cleaning temperature

This is accompanied by slight variations in heat compatibility: Plexiglas XT is only stable up to 70 degrees, Plexiglas GS, however, up to 80 degrees. If you adjust the temperature of your steam jet, you should take this into account. If you do not know which acrylic glass to use, simply never set the temperature above 70 degrees.

No mechanical-rotating Plexiglas cleaning!

For larger surfaces (industrial), the use of a steam jet is also recommended. Mechanical cleaning equipment should be avoided urgently. Because these work on the principle of a rotating plate. But if there are dirt particles on the Plexiglas, you will scratch the surface.

Steam jet pressure during cleaning

For this reason, clean the Plexiglas gently with a steam jet in the outdoor area and allow it to dry as independently as possible. The pressure of the steam jet can be selected between 50 and 100 bar.

Tips & Tricks

For the interior there are cleaning products for PMMA plastics, which develop a dirt and water repellent effect. These are so-called plastic cleaner and care combinations (AKU). If it should show after cleaning that the acrylic glass is also damaged on the surface, there are also methods to remove scratches from Plexiglas.
