Is a pressurized sprayer any better than a regular spray bottle in this case? Do you have a water deionizer (they seem expensive)?
I use pressure washer for hose connected to double chuck water deionizer ...only reason I use a flow master is doesn’t use much water and I can do in my garage ..given California is still in somewhat drought conditions want to do my part ...if I’m lazy I will just use water deionizer (double chuck ) foam down ..spray off and it will dry in sun without spots
