Since failure using this product appears to be sporadic, I'm wondering if existing contamination is at the root cause of the problem. Even though some are using alcohol this may
not be sufficient enough to deep clean within the pores of the material.
The products we use are chemical formulations. If these chemicals come in contact with or react with other or existing protectants that are still present then this could possibly be what some are seeing. Case in Point
I cleaned a dash using 1Z Cockpit Premium
and this was the result:
Clean the same area using Meguiar’s All Purpose Cleaner
so not all cleaners are equal.
Just a thought is all.......
