Hi all
does anyone know what causes black lines at the bottom of painted wooden windows
Its not the rubbers as there isn't any
the frames were only painted last year
it's not the water that we are using as we clean the ups with the pole and trad the downs
we only use fairy in the water for the downs
any ideas ? The customer thinks it's us and i just don't know whats happening
I've blamed the paint and suggested he gets on to the painter
Your thoughts
