Spraying CC550 onto glass

Yes, gloves and eye protection. I’ve since switched to Safe Restore and keep a bottle with me all the time. If I have several windows to clean I’ll pour a little into a bucket (not a BOB) and dip my strip washer in it. This works well. Just be very sure to not get it on anything other than the glass. It’s a good idea to have running water nearby too. A word of caution: I once rinsed Safe Restore off a pane and just the mixture was enough to stain the paint below the window. Ouch! So much for “Safe” Restore.

you have to rinse everything it will come into contact with before, during, and after rinsing

Just realized that I put the post in wrong space just go back a few posts

I forgot to mention that I did that before and after…after the 1st window…and there was still some discoloration…whince

I must of not of explained it properly.
Get a sponge like those you use to clean floor put it on pole high up or short handle for lower work.
This way you have tool just to apply all your chemicals safely without ruin your scrubbers cloths or have chemicals residue left on you other tools etc.
Then instead of spraying chemicals, use a squirt or squeeze bottle to apply your chemicals directly on the surface that needs to be clean.
Or on scrubber it self.
