Will a Dawn wash remove all old products?

I Black Iced my car 6 months ago, gonna strip and polish again, will a good "Dawn" wash remove all old products?

IME Dawn is extremely *INEFFECTIVE* for LSP removal. I suspect that people often confuse the conditioners/whatever (sorry, I`m no chemist) that it leaves behind, which can interact in different ways with different LSPs, for genuine stripping. Dawn sure doesn`t strip LSPs for me, with the possible exception of fragile beauty-waxes.

If you`re gonna polish again anyhow, I`d just let the polish cut through it. Unless it`s a very fresh/durable/etc. coat of LSP it won`t cause any trouble.

Agreed. I don`t really see any use for Dawn when it comes to detailing

It has been pretty much conclusively shown that Dawn doesn`t remove LSP`s but just hides the beading -- after a Dawn wash just wipe with IPA and the beading returns because the surfactants have been removed by the IPA.

Not really, you might have to step up to a clay bar, CarPro Iron X Snow Soap and / or a compound buff to remove the LSP.

If you want the best way to remove the old product, clay the car after a good wash.

Don`t forget valugard ABC three step wash

I imagine that any old product remaining would be instantly removed the minute you applied a polish. If a polish can reduce or removes swirls, than any LSP wouldn`t stand a chance.

If you`re going to polish or clay it`s a moot point, but otherwise I`ve read that a 50/50 mix of isopropyl alchohol and water (spray on/wipe off) does the trick for most all LSP`s.

IMHO IPA (@70%) & "claying" won`t remove most durable LSPs. Dawn won`t remove them either.

The only way IMHO to remove them chemically is to use a solvent type product like Prep All or mineral spirits. Wheel acid will remove LSPs - lol.

But, this really doesn`t matter. Any polishing will remove LSPs. Anyone who tells you you need to "strip wax" before for polish paint - either hasn`t polished paint or is a bit lost in the process.

If polishing car remove clear coat - it can remove wax. Don`t worry about that.

Waiting for warmer weather, never used it before but I have chemical guys citrus wash red we will see if it works.

I`ve tried it and it does not. After you have used it and there is no beading give it a quick wipe down with IPA and the beading will come back. The IPA removes the sufactants left behind by the wash soap which give it the appearance the LSP is gone. Read through the link in Post #4 above.

.."claying" won`t remove most durable LSPs....

I`d alter that just a little and say that "properly done, i.e., GENTLE claying won`t remove LSPs". I`ve done a whole lot of claying (often spot-clay a little at every wash) and how you do it, and what clay you use, can really make a difference in this regard. A long time ago I posted my test for how to tell if your claying is stripping, dunno if anybody ever tried it....

In the 41 years in business,I have never used alcohol or had to remove old polishes or wax. Most cars people bring me are dead and car wash whipped to the point of breached clear coat. Detail products, no matter what is claimed by the industry offer protection for a frightfully short period of time. Many less than 2 to 3 months if that. I correct as best I can, given the reality of the situation, but never attempt to remove a product that may not be there anyway. I know many use clay here as well. Sounds like a good idea if anything.

I use presol or 3m wax and grease remover. But the OP did indicate they where going to `polish` again. So if they really mean polish then no point. If they mean they are going to put another coat of LSP on it, then really no point there either.
