On the Zaino front (and every wax) do not use dish detergent to "strip the wax."

(Makes you wonder how good a product is if the developers recommend this step....maybe they have a good rubber/plastic restorer that they are trying to sell?).
As I've stated many a time - I disagree.
Using properly diluted Dawn on plastic/rubber will do nothing. If those areas of your car are already in bad shape, it actually helps strip the loose, black residue off. Then applying a sealant on top will help restore the rubber to a protected black finish.
I have detailed 3 SVTs alone that when you touched the rubber trim, it left black residue on your hands. Dish soap is stronger than a car shampoo and helped to remove the black residue. Once the black residue stops coming off on the wash mitt, then it's prepped for sealant.

There is absolutely nothing wrong with using a Dawn or any other dish liquid on your paint - as long as you use it sparingly and infrequently. When diluted and rinsed properly, dish soap does no harm to your car.
To all those screaming that dish soap is harmful:
Prove it. Otherwise, please refrain from posting unsupported information.
Instead of using heresay and undocumented, unproven statements, test it for yourself. Take some diluted Dawn and wash a small section of rubber trim on a brand new car. Does it visibly do any "harm"? No. If anything it will remove whatever product that was on there. Car shampoos merely wash off the dirt. Apply sealant and the trim looks brand new.
I have done it on every car I have owned. Brought it home, dish soap to wash dealership junk wax off and applied Zaino. Repeat process every couple years. Even after 6+ years, my rubber trim and black window trim looked brand new, glossy black - local CEGers can attest to that.
