Chemitek Cement Removal Agent (CRA) is a professional, biodegradable cleaning solution specially formulated to remove cement, lime, mortar, and mineral residues from solar panels and surrounding structures. It effectively dissolves construction-related contamination without damaging the glass, frames, or anti-reflective coatings of photovoltaic (PV) modules.
Designed for use after nearby building or maintenance works, CRA restores the optical clarity and efficiency of affected panels. Its non-corrosive, pH-balanced formula ensures safe and thorough cleaning while maintaining manufacturer warranty compliance. Ideal for residential, commercial, and large-scale installations, CRA is a reliable solution for post-construction solar maintenance and long-term panel protection.

CRA is a professional cleaning solution specifically formulated to remove cement, lime, and mineral residues from solar panels and surrounding surfaces.
The product effectively dissolves and lifts construction-related deposits without damaging the glass, frame, or anti-reflective coatings of photovoltaic (PV) modules.
It is a biodegradable, non-corrosive, and pH-balanced formula, tested and approved for safe use on solar installations — ensuring a thorough clean while preserving panel integrity and optical performance.
Cement residue
Lime and concrete splatter
Mortar and grout stains
Mineral and construction dust buildup
Cement Removal Agent is a biodegradable product designed to be as delicate as possible with the components of the solar module (ARC, silicone and aluminium frame).
Chemitek Cement Removal Agent (CRA) must always be diluted with pure or demineralised water before use.
The correct dilution depends on the level of cement or mineral residue present on the solar modules or surrounding surfaces.
Apply only to cooled, dry panels and avoid strong sunlight during application.
Suitable for panels with light traces of construction dust, lime film, or fine mortar spray. Apply evenly, allow 5–10 minutes dwell time, then rinse thoroughly with pure water.
Ideal for panels with visible cement or mortar splashes. The higher concentration improves dissolution of mineral deposits while remaining safe for glass and coatings. Dwell time: 10–15 minutes.
For thick or hardened cement buildup and stubborn mineral residues. Apply liberally, allow up to 15 minutes contact, agitate gently, and rinse thoroughly. Repeat if necessary.
The product is more effective when applied on cool, dry panels.
Avoid cleaning under direct sunlight or on hot surfaces.
Do not allow the product to dry during application.
For targeted cleaning or smaller affected areas, dilute CRA according to contamination level (typically 1:2 to 1:10) and apply directly to dry panels using a spray bottle or pump sprayer.
Spray evenly over the contaminated areas.
Allow 5–15 minutes of contact time depending on residue thickness.
Agitate gently with a soft to medium brush to loosen the deposits.
Rinse thoroughly with pure or demineralised water.
If required, repeat the process for stubborn or hardened residues.
This method is ideal for spot cleaning after nearby construction or maintenance work.
For broader contamination — such as overspray from construction dust or cement wash — CRA can be mixed in a tank or applied using a low-pressure sprayer or robotic system.
Dilute between 1:5 and 1:10 in pure water.
Apply evenly across the affected modules.
Allow up to 15 minutes dwell time to dissolve cement and mineral film.
Brush and rinse thoroughly using soft or rotary brushes with pure water flow.
This method ensures consistent coverage and safe removal of residue across multiple panels without excessive scrubbing.
Always perform a test patch before large-scale use.
Do not use metal tools or high-pressure jets on module glass.
Avoid contact with aluminium frames — rinse immediately if contact occurs.
Never mix CRA with other cleaning agents or acids.
Chemitek is a global leader in the development of innovative solar panel cleaning and maintenance chemicals. Their range is designed to maximise PV system performance while protecting the environment. All products are biodegradable, TÜV-tested, and approved by major solar module manufacturers.
Unlike general-purpose cleaners, Chemitek products are specifically formulated for photovoltaic (PV) glass. They remove soiling effectively without damaging anti-reflective coatings, seals, or frames. Each product targets a specific issue — such as organic soiling, lichen growth, or static dust — and has been tested for compatibility and warranty safety.
Yes. Every Chemitek solution is biodegradable, pH-neutral, and non-toxic, designed for use in sensitive environments including floating PV systems and agricultural installations. Wastewater management guidelines are provided to ensure compliance with local regulations.
SWP is a 2-in-1 cleaner and antistatic protectant for regular maintenance of solar panels, removing dirt, pollen, and organic residue.
LRA, on the other hand, is a specialised treatment for stubborn biological growths such as lichen, moss, and algae. It’s ideal for panels in damp or shaded UK and Irish environments.
Yes. Chemitek holds letters of conformity from leading module manufacturers confirming that its products are warranty-safe when used according to the official instructions. They have been independently tested by TÜV SÜD to ensure full compatibility with solar glass and frames.
Cleaning frequency depends on the local environment. In the UK and Ireland, panels typically benefit from 1–2 cleanings per year using SWP, with additional LRA treatment as needed in high-lichen or coastal areas. ASA 2.0 can extend the interval between cleanings by up to 50%.
Yes — positively. By removing soiling and preventing recontamination, Chemitek products help recover lost yield caused by dirt and biological buildup. Field results show 3–5% performance improvements after cleaning with SWP or LRA, and longer-lasting cleanliness when ASA 2.0 is applied.
Chemitek’s full range — including SWP, LRA, ASA 2.0, and other cleaning agents — is available through their official UK & Ireland distributor, Solar Clean Robotics UK.
