This is a very common issue, especially if the car has been on the road for a number of years. The cloudiness is usually due to fine surface scratches and sometimes yellowing that appears through wear and tear over years of usage.
The best Renovo product to resolve this issue is our Plastic Window Polish will remove these surface microscopic abrasions and this external yellow staining when used together with a microfiber cloth and some elbow grease. This polish can be used to clean and condition perspex as well as flexible plastic but is not suitable for use on glass. For best results, follow these instructions:
1). Prior to application of Renovo Plastic Window Polish ensure that the window is clean and free from dust particles by washing with a soft cloth and warm water. It is not advisable to use cleaning detergents on plastic windows!
2). Shake the bottle thoroughly.
3). Use a soft cotton duster/cloth and apply the polish with a little pressure using circular movements to rub well in, apply more pressure on areas which are more scratched. It is best to add small quantities of polish frequently rather than a large amount all at once until the whole window has been covered.
4). Allow the polish to dry and then use a clean soft cotton duster/cloth to remove/polish off the coating of polish.
The interior and exterior of the window should be polished in the above manner to achieve best possible results! Our Plastic Window Polish will not remove clarity defects that are within the plastic but it will remove external/surface scratching and yellowing.
