I use it much stronger than the instructions state.
Also, it does not keep long in the bucket. If the water gets dirty l find I lose slide and grease cutting totally. Unlike Fairy etc, adding more GG3 to the dirty water does not seem to help.
I change the water when it gets dirty and wring all the dirty water out of my applicator before putting it into the fresh solution.
Must say though, that most of our employees don't like it. Maybe due to the above. Maybe because they find it hard to see the solution on the galss and leave bits. I never have this problem.
GG3 it very good and comes into it's own with commercial and pole work. No need to detail at all and no white suds all over the sills. Great stuff!
Also, if you have windows which sometimes are done with WFP and then trad, the GG3 does not leave soap residue.
