Hi Hardsell,
The price is a bit daunting but from the mix ratio you gave I'd think that the gallon would last a good while. Do you find that so?

10:1 is about $2 qt. I can't think of a cleaning product near as good for that price. Daily and light cleaning can be diluted at 20:1.
I bought 2 gallons and got discount. I think about $20. I have given family members part of it and have not broken into the 2nd gallon.
One of my choice uses is on my stainless BBQ grille. The hood accumulates a lot of grease residue on the back side. For the slanted surfaces I spray then lay paper towels over it and spray again. The towels will cling and give the grease time to dissolve. Great for kitchen range and hood vent also. Soak the burner rings and drip pans for thorough cleaning.
I also clean the stained kitchen cabinets with it. So far it has not damaged the stain.
Combined with a Dyson you can have a really clean home.
