Glass Gleam 4 - Glass and Window Cleaner - Highly Concentrated - 1 Gallon Makes 512 gallons of RTU Product

This is by far the best glass cleaner of all time ! I own a cleaning business and do a lot of windows everyday. You can make it by the liter all the way to a gallon for the space that needs to be cleaned. It took off all grungy dirt and I'm telling you the windows truly sparkles when I was done. Simply spray or sponge on the glass squeegee then only touch the four corners and wella the glass just shines! Totally impressed with this stuff. I'll always have it in my cleaning supply cabinet

Hushband uses for window and roof bussiness and he loves it. This bottle last him a good while. You only need a capful for a big bucket.

Ive cleaned glass for 30 years. This is it. Nothing is better. Goes great with Super Slip

Don’t have to use a lot of soap to clean glass. Prefer to use glass gleam 4. This does the job

Very good

Lamentablemente el producto no es lo que esperaba. No hay diferencia alguna entre utilizar vinagre o este producto. Hace el mismo trabajo. Las manchas de los cristales no se eliminan aunque utilize una esponja para limpiar sartenes.

I work for Glass Masters, Professional Window Cleaning Company. Glass Gleam 4 is the best product I have ever used, I am extremely impressed with this product! I will be ordering this from now on!
