I’m surprised they don’t charge more for fairy liquid just shows you how much they make on these other window cleaning products if fairy can be got for a £,they still haven’t produced anything that glides like fairy liquid why would they they say buy 4-5 ltrs of this stuff that has no slip and then buy another product to put in it that gives you some,but the thing is it still doesn’t work so you’ve spent 60-80 quid on 2 products that are total toilet.
About 10 years ago I used GGSpot on a job inside they looked fine when I left no sun,when I went back as the lady complained they looked dreadful turn marks galore I’ve never left a job like it,I should have known when I was cleaning them it was squeaking like a tortured mouse 🤣🤣 🐁
