Just filled the tank full to brim so more than 650 litres plus 100 litres in containers added 7 ml of Vision. Fairly big day tomorrow, mix of white painted woodwork frames and white Upvc windows.
I shall be watching very closely what I do and the results. I have been cleaning all these windows every 6 weeks for 7 years, I know them all very well.
I will post results...
Tapping fingers PJ, tapping fingers.
