Product Information

Efficient cleaner to remove yellowing

 

Dilutable cleaner for effortless removal of yellowing and yellowish algae in gelcoat, plastic and paint. Easy and efficient application with a pre-wash brush in the foredeck area, as well as the water pass, exhaust area or the mirrors leads to an immediate effect without waiting time. Due to the neutral formulation of the No Yellow Cleaner, surfaces such as plastic, stainless steel and aluminum are not attacked. Effective against algae, rust, soot and soot in the exhaust area and rust stains.

Cleaner can be used undiluted or diluted 1:4 with water. Simply apply, leave to take effect and rinse. Mix in the wash bucket, apply to the areas to be treated with a sponge or pre-wash brush. Then rinse with water or neutral shampoo. Avoid galvanized surfaces. The No Yellow Cleaner does not work on yellowing caused by UV light. We recommend closing the open-pored gelcoat after thorough cleaning by polishing and sealing to prevent rapid yellowing.

 

Check for material compatibility before use. Do not use on galvanized surfaces and real wood. Only use on washable surfaces. Do not use on hot surfaces. Do not allow to dry.
