Ultimately I find it hard to get past the fact that all the raw material guys, the ones who make the building blocks we use to make your products, the ones who tend to be the multi billion dollar, global entities... recommend waterless washes with {active ingredient} levels in the region of 3-5%. Extrapolate it and the highest theoretical concentrate level would be 33x (anymore and there would be more than 100%). In actual practice, it is generally unrealistic to hope for more than 50% active (the formulations would generally not be stable higher). This brings us to the general idea that a rinseless cannot be comparable to a waterless when at more than about 20:1. Since many rinseless products are diluted far more than this there is something awry.As I see it, it is boiling down to whether I believe the global entities with their advanced R&D facilities and huge budgets or one of the (relatively) miniscule automotive specific manufacturers. Certainly if it were to come down to a question between my company and BASF (for example), I wouldn't for one second hesitate in telling you to believe BASF.
I just read your post.. Can you fill us in on your thoughts as far as D115 as a dedicated rinseless wash? I wasn't aware of it having a new description on here.. What exact dilution do you use it at? I'm surprised no one has mentioned using it. Can you maybe offer a review? I'm sure alot of people would find it interesting.
