Hi just spent 1.5 hours in the shed , new of course.

I have a reasonable flat table with removalists rug on top 1200,mm ?2000 mm,and have just cleaned my sail windows with micro fiber cloth and light car wash mixture.
I am very happy with result ,and suggest that YOU do the same.
Chemical you say, pfffft.
"Stoked" that's when I can See.
Nike. Just do it.
So much more fun when you can see what to hit.
Wagga wagga .biattch..Yew

Clean and vision .
Super stoked Jamie.

Try glass cleaner Appleman - good for windows.

I know where you can get some for a bargain.

A lot cleaners/polishers can harm the plastics over time, shortening their life. Vuplex was recommended to me some years back as a proper plastic polish and it works pretty good if you want to try it. A clean sail means that you see the jet ski before it cleans you up
