Anyone recommend PVCu cleaning solution.
Non abrasive, wipe on/off. needs to able to be used by abseilers.
For window frames that are 9 years late in getting cleaned.
Tried B&Q gear, but it doesn't touch it.
I used to have a company that did all this sort of stuff for me, but it seems he has packed it in so I am trying to find my feet doing it ourself.
