Add about 1/4 Fl. Oz. of GG-4 concentrate per gallon of water. (A dilution ratio of 1:500). Or about 1 ounce per 2-1/2 gallons of water. The actual amount needed depends on variables such as water hardness, temperature, humidity, rubber quality, dirt on glass and personal preference. Some experimentation may be needed to find the optimum dose. Do not exceed twice the recommended dose.
The cost is of using GG-4 is pennies per bucket. Window cleaning expenses are almost all labor. The small cost of Glass Gleam-4 is more than offset by faster production with less effort, compared to dishwashing soaps or home-brewed solutions, for example. Dishwashing soaps often differ from one purchase to the next, leave a film on the glass (especially noticeable on mirrors), make tool handles slippery when wet and then tacky while drying, have excessive bleeding and too much foam, to name some drawbacks. Dishwashing soaps are intended to wash opaque dishware rinsed in hot water. A reflective residual film leaves a shiny surface and lots of foam in the sink are key selling features of dish soaps. GG-4, in contrast, is a professional window cleaning solution designed for vision glass and the needs of the window cleaner. You and your customers will notice the difference. Plus you can use Glass Gleam-4 as a sales tool - that you use the best professional products.
