GG3 has plenty of slip if you use 1/2 oz. per gallon of water. The 1/10 oz. per gallon recommendation by Titan Labs is just their effort to win some dishsoap users over.
Definitely true, you gotta adjust the ratio for your own use. I don’t know why they recommend using that small an amount.
I’m currently using GG3 and I’m new to the WC game. The squeegee rubber seems to grab the glass way too much for my liking. Dawn or TSP? Which one should I try first? How much does TSP cost and where can I find it? Thanks,
