I often use the car plan windscreen wash, not so much in the water I use to squeegee with, more so in my sprayer for the glass I can't use applicator and squeegee.
Though on some inside work, offices and so on, with large panes I use the sprayer to mist glass and then squeegee it off. Less mess than using applicator, useful over top of computers and so on.
I water it down at least 25:1 and usually add a little drop of Unger liquid too (helps with slip)
I haven't thought of using it in conjunction with my WFP though. On certain cleans I could see the advantage, no suds for one thing.
But I wouldn't add it to the water. would just dip the brush into a bucket, or maybe pour some directly onto the brush.
I'm always happy to experiment
Ross, (and anyone else come to that

It may have changed in recent months, but Somerfield/Kwik Save were selling it at £2.99 for 5 litres
Even if you only use it in a sprayer to mist & buff, its way cheaper than any other stuff......well, ok, a few drops of GG3/4 or Unger liquid etc work out pretty cheap too.....so ignore that bit about it being way cheaper
But it does have its uses
