My spot free is frothy. It's not so and it's not wax as it doesn't taste like anything except water, but it's frothy. I'm looking for answers for the reason why if anybody has any suggestions. Real suggestions, not just pretend experts telling me to change a filter. I've already done that. Almost any help would be useful. Thank you

Where are you seeing "froth?" In the permeate holding tank?
What is the TDS of the permeate?
If you are sure it is not soap or wax, I would bet you have a check valve failing on your presoak or tire cleaner in one of the bays. Pull your production line out of the tank and run those functions in each bay individually, and see if you are getting a back feed of one of the products. A trace of these products can give your the froth. As Buckeye noted, what is your tds in the tank?
