Jason, hey how you doing! This forum has changed, hasn't it?
I'm not gonna say whether or not Dawn should be used, but I don't think it's ability to remove waxes is overrated. In my experience, it was strong enough to remove multiple layers of Klasse. Also, having a higher Ph is a byproduct of other, more harsh detergents in the shampoo. Ph, by itself does little in terms of harshness or cleaning ability. Dawn has a higher Ph than car shampoo because of the harsher, grease-cutting detergents it contains.
Now, Dawn may not COMPLETELY remove everything the way a solvent would, but it'll definitely remove enough to negate any bonding issues with sealants. What I think is overrated is how ppl are in mortal fear of applying sealants over waxes....even if there is only a trace amount left.
Haha!!1 I agree 100% with the sealants over wax thing, its way out of hand!
Ph has nothing to do with detergent or cleaning properties, what we are concerned with is how a liquid (in this case dawn) dissolves proteins. Ph is a chemical make up characteristic, nothing more. Cleaning ability is determined by added surfactants, detergents mixes, and wetting agents and things of that nature.
This is a quick and dirty explanation of Ph cut from a website.

What is pH? Good question! It is the measurement of the concentration of "hydrogen ions" (shown in chemical notation as H+) in relation to the concentration of "hydroxyl ions" (shown in chemical notation as OH-). An excess of H+ (hydrogen) ions over OH - (hydroxyl) ions makes a solution an acid. Conversely, an excess of OH - (hydroxyl) ions will make the solution alkaline (often referred to as basic). All solutions that are made up of water can be measured for their pH. The pH scale runs numerically from 1 to 14. On this scale, a solution that has a pH from 0 to 6.9 is considered to be an acid. It is acidic because it contains a larger amount of hydrogen ions. A solution that measures from 7.1 up to 14 on the pH scale is considered to be basic (or alkaline) in nature, because it has a larger amount of hydroxyl ions. As you may have guessed, a pH of 7.0 is neutral because it contains equal amounts of hydrogen (H +) and hydroxyl (OH-) ions. Pure, unpolluted rainwater or distilled water is neutral, because it has a pH of 7.0. It is interesting to note that the pH scale is a logarithmic scale. This means that a change of one pH unit indicates a ten fold increase in the concentration of hydrogen ions. For instance, a solution that has a pH of 2 has ten times as many free H+ ions as a solution with a pH of 3! Non-aqueous liquids or solutions (solvents such as gasoline, mineral spirits, chlorinated safety solvents) have neither hydrogen or hydroxyl ions. They do not have a pH, because they do not contain any water. As we mentioned before, pH is a characteristic of water solutions only. Without any water, we cannot have a pH.

Some of you may be interested to know Dawn has also crossed over into taxidermy, for degreasing skins before mounting them.
