Mixing up a few gallons in a bucket and disposing it after 1 wash is a bit wasteful. Using the Garry Dean method keeps the solution clean so a lid to be placed on the bucket saving the solution for future use.
How long will this solution last before it becomes not usable? I've been doing this to get a couple washes and it seems the older it gets ( not longer than 1 week ) the harder it is to wipe off. Using 2oz with 1 gallon of distilled water and 16-1 ratio in spray bottle also with distilled water.
