Clean and restore flexible vinyl, Perspex and glass windows with the right products
Why do vinyl windows go brittle, cloudy and yellow?
Clear vinyl windows are made flexible by plasticisers, slippery beasts that are easily leached from the surface. Solvents and unsuitable cleaners speed the process, leading to brittleness.
Cloudiness and discolouring are caused by dirt, microscopic scratches and contaminants that penetrate the very soft surface of the vinyl. Wax and oil cause cloudiness and yellowing, so waxy dressings should be rigorously avoided.
Deterioration of vinyl is accelerated by UV in sunlight, and unlike coloured vinyls, plastic windows have very little protection.
The solution is to remove scratches and contamination and then, most importantly, to protect the surface with a coating that inhibits loss of plasticisers and provides UV protection.
