My tech is working on a more permanent solution wired into the brake light system. In the meantime, I bought a Vevor Deionizing car wash system on a cart- relatively cheap, and has a TDS meter. I washed the vehicle early this morning and used a two bucket method, a fancy car wash shampoo without any additives or polishes--made by Gyeon and used a drying cloth from Blackline, which is super absorbent and not a waffle weave. I also used my air compressor to blow out water in the crevices. I also used a light application of Lexol on the leather interior. Yesterday, my tech sent a guy to polish the dash, which I didn't really "get" but the results are amazing.
I put the tonneau back on after washing but the results are pretty stunning.
