have got a few windows that are covered in the stuff i would normally try and shy away from this kind of job but they are a really nice customer who have had major building work going on for about 8 months and have said i'll try and find something for this, its left milky marks/ residue over glass i think it needs some kind of solvent, but what exactly cheers for any replys.

Hi John
Paint fixer? not sure what that is - do you mean PVA or is it paint primer?
PVA is water soluble - warm water best.
Otherwise I would try in this order
White Spirit
Brush Restorer
Isopropyl Alcohol
and lastly 'cos it can burn the paint off Cellulose Thinners.
Hope that helps.

if it was me, think i would just get  razor blade srapper on pole for that, make sure you have constant water flow while scrapping.

think i'll give the white spirit ago 1st along with a sharp blade, and see how that goes,
