We have a contract to clean windows on a large building. We cleaned these windows a few years ago and and they haven't been cleaned since.  As you can imagine the glass is pretty dirty.   The last time we cleaned these windows we had to wash them several times to get them right.  Which chemical would you recommend to  speed up the process?

Any decent degreaser and squirt of washing up liquid in a backpack or pump sprayer with a good dilution ratio and away you go. Small sections at a time and don't allow it to dry on the glass. Scrub, rinse, clean the whole place like this and then reclean with pure. Usually works for us.

Tell them they need to commit to a higher frequency of cleans. Silk purse sows ear ‘n all that.

Bin the contract, unless they go for a regular clean.

i use hot pure water and virosol for first cleans/really dirty windows and frames.i either use a backpack or spray bottle for application.......works well and should speed you up a bit.....
