Metal Oxides Removal Agent

Biodegradable concentrated removal agent for metal oxides residues

Removal agent for metal oxides residues

The Metal Oxides Removal Agent (MRA) stands out as a specialized solution tailored to eliminate metal oxides found on PV modules. Carefully designed as an eco-friendly biodegradable product, it handles the module’s components (ARC, silicone, and aluminum frame) delicately, offering ease of use and posing no risks for professionals. Chemitek’s MRA has been proven safe to use on PV panels by the international german laboratory TÜV Sud.

The MRA is readily biodegradable and ensures effectiveness in the removal of the contaminants without compromising the materials and components of the module, supporting structure and the roof (if applicable).

How it Works?

MRA is a concentrated solution that requires dilution with water before application to the contaminated solar modules. This innovative cleaning agent harnesses a unique combination technology to effectively dissolve and break down metal oxides. This potent formula deeply permeates the metal oxides, effectively softening and loosening them for easy removal.

Using the Metal Oxides Removal Agent is straightforward: dilute the product in water according to the recommended ratio, apply directly to the affected area, and the reaction will be instant. Then, brush the surface using a soft brush and finally rinse with soft water. Following these simple steps will leave solar panels looking revitalized in no time.

This product is a remediation agent and should be used as such. To prevent the recurrent use of the MRA on each cleaning, act preventively protect the modules by applying an antistatic coating such as our Antistatic Solar Armor (ASA).


  • Easily removes metal oxides, such as rust and aluminum oxides, that are otherwise very hard to remove without scrapping and risking damaging the modules
  • Developed specifically for PV modules and tiles
  • No more scrapping - reacts instantly with the metal oxides particles and loosens them
  • Tested by TÜV Sud - does not damage the ARC, silicone, and the aluminium frame
  • Readily biodegradable and environmentally friendly
  • Act preventively and protect the modules, in case of frequent contamination, with one of our antistatic coatings to avoid the recurrent use of the MRA

Suitable for the following cleaning methods:

  • Manual brushInstallers of photovoltaic plants
  • Water fed pole
  • Electric Rotary Brush
  • Robot
  • Brush on tractor

  • The surface of photovoltaic solar panels must be clean to ensure full operation and maximum efficiency. Any kind of dirt that may be on the surface of the solar module, be it dust, pollen, tree sap, bird droppings, sand, salt crystals, etc., will reduce the light transmission, i.e., reduce the amount of sunlight reaching the solar module cells, and thus the panel will produce less power.

  • To the naked eye the panels may appear clean, however there will be dirt accumulated, even if it is just the air pollution itself. A simple test to see if your panel needs cleaning is to wipe the surface of the panel with a white cloth or cotton pad before the actual cleaning.

  • According to recent studies, when a solar panel is very dirty it can lose up to 50% of its efficiency compared to a clean solar panel. However, an energy loss of 10 to 15% can be observed in panels with some dirt.

  • In fact, rain or wind alone does not wash the solar panels. The wind carries dust particles, and the rain, specially in small quantities, will catch any dust in the air and, when it dries, will leave dirt spots, thus making the solar system less efficient.

    A simple way to illustrate why the weather alone does not wash out the solar panels is to look at the windshield of your car. If you leave your windshield dirty for a long time, you will lose visibility due to accumulated dirt, but thanks to the cleaner that you apply and the windshield wiper, you can wash the glass and regain visibility in no time!

    In this way, the solar panels are like the windshields of your car, except that they do not have readily available liquid for washing the solar panels associated with the windshield wiper.

  • For the warranty on your solar panel to remain valid, you should use solar panel cleaners that meet the manufacturers' requirements, such ChemiTek’s products.

    However, as a rule of thumb, use products with a neutral pH, that are tested by international laboratories and approved by the solar panel manufacturers themselves. This will rule out any negative effect of their use on washing solar panels.

  • The recommended dilution for the Metal Oxides Removal Agent is between 1:5 (1 part product in 5 parts of water) and 1:10 (1 part product in 10 parts of water).

    To find the best dilution for a specific plant, we recommend starting the highest dilution (1:10) and checking how effective it is. If it is not effective, then keep reducing the dilution until you find the one that removes the contaminant with ease. Only on very extreme cases should you decrease the dilution below 1:5.

  • The MRA is a specialized solution tailored to eliminate metal oxides.

  • Metal Oxides Removal is a biodegradable product designed to be as delicate as possible with the components of the solar module (ARC, silicone and aluminium frame). The product reacts chemically only with the contaminants and emulsions the particles so that they can be rinsed off easily.
