Simoniz Ultra U390005 is advertised as a high 13.2 PH soap. Several people have suggested it is a better additive to the Correct and the Kleen-rite Ultra products than Simoniz Foamy Additive, which I've used for years. So what exactly does the high PH do as a cleaning additive. Is it different that say the Kleen-rite Vanilla Ultra, which someone said is made by Simoniz. I've had no problems with the Foamy Additive but wonder if I am into dangerous territory by mixing these chemicals if one is "high PH" and the other, Correct, is also advertised as an alkaline soap? Thanks
