Hi Dazmond & Jonnyald,
Many thanks, I will get hold of some cif & non scratch scourers & go lightly lol.
I saw some spray on cleaner for upvc earlier, but I guess price wise it probably is not worth it, & probably still requires the same amount of scrubbing.
I get my motor back tomorrow from the garage, it is having a new clutch & rear shocks, & is going to cost a lot.

, but atleast I need not worry about them going again anytime soon, & I am ready to go door knocking.

Thanks again.
Ian.
