the correct dosage for unger liquid is 100ml per 10ltr. this gives a ratio of 100/1.
I tried the unger liquid for a few days & thought it was rubbish. it smears like mad on some glass. you cant always see the smears unless you look at the glass from an angle, when the sun gets on it it's even worse, but look straight on & all seems ok. terrible stuff. on a particular window i've done for 3 years it was realy bad, smears all over, tried, tried & tried again, no better.went back to my other detergent, did it again, perfect!
for me it's (per 10ltr of water) 10ml-gg3/4 + 10ml of squeegee off. perfect in all aspects!
