A Dawn wash (~1oz per gallon for wax/oil/silicone removal) will do absolutely no harm to any vehicle exterior components. Dawn will strip the surface dressing (sheen) from plastic components but not the internal intrigrity (structure) of these components. These components are exposed to much harsher daily assault by their exposure to the environment than an single Dawn wash will ever impact on them.

The Dawn washing procedure should only be needed if one does not plan/need to clay and polish after washing. If one is going to clay or just polish prior a new apllication of a LSP, there is no need to Dawn wash. Just use your regular vehicle shampoo.

Dawn/Suds/Lubricity. Dawn suds very well and even though suds do not equal high lubricity, some of the increase resistance when washing with Dawn is due to the stripping of the wax/oils/silicones from the washed surface. Using proper washing techniques, soft wash mitt/towel, a good cleansing and high surfactant shampoo will decrease the chances of self-induced swirling more so than a high suds producing shampoo. Suds do look great and add to a false sense of security.

Dawn (blue) is recommend as a household available product for this degreasing task because it has been shown to have the least amount of cosmetic additives (i.e. hand softeners).

A small bottle of Dawn(blue) is usually less than a $1. Dawn is also a great tire cleaner.
