Debate Over LSP Removal Settled
We have all read the debate about removing LSPs. Some say Dawn, others CG Citrus (full strength), others paint cleanser i.e. P21 while others say only polishing will remove LSP. I used to be in the paint cleanser and CG Citrus camps, but thanks to a "misadventure in detailing" I got to test out all of the above. Here's the situation: two weeks ago I polished the car, and wanted to try a new LSP combo (BF Wet over Ice, but using Natty's Red as initial wax and BF spray as topper). I didn't let the sealant cure long enough, and the red wax mixed with the curing sealant and turned my Alpine White car pink...
I waited a couple of weeks, and it didn't fade. So, I figured I'd use this as an opportunity to see what will remove LSP the best. I started with Dawn...nothing, bupkis...nada. Full stength CG Citrus...the same. P21s with a hand applicator didn't touch it....not even a slight fade. I then tried P21s with LC hydrotech tangerine pad and there was significant fading but complete removal. I started to reach for the Menz 400, and saw a sample of Menz SI 1500. I tried it with the LC Tangerine and this took it right off. I know what you're thinking...where are all the pics. Well, I have a 3yo and 6yo that insist on "helping" me, so it was hard enough to complete the test, let alone take pics of all runs. I do have an after shot..
Before After
Overall, no soap will take LSP off. You can theorize all you want, look at indirect measurements like loss of beading, but this is a direct measurement. LSP was pink, when removed, car is back to white. I think paint cleansers would work on older LSP...closer to failing, but that's about it. If you want to remove your LSP, reliably, you have to polish.

Awesome info. Thank you for giving us a genuine no b.s. test. Even if it was unintended. Lol

Re: Debate Over LSP Removal Settled
Actually I switched from CG citrus red to their new clean slate wash. It will remove new layers of waxes and sealants extremely easy. It's what it was designed to do. I made a thread about having to remove a fresh layer of sealant and wax on a co workers car.
Just did it over the weekend, used 3oz in my foam cannon and about 6oz in my wash bucket. It took off literally everything on the car and we were talking about product that has only been on a month or so.
But I'm getting the feeling here any time I bring up a fantastic product that works and is not known by AG I get shut down lol

Re: Debate Over LSP Removal Settled
Wonder what's in clean slate to be able to just strip all LSPs? Seems like a tall order, not saying it doesn't or won't work just curious on what chemical they are using to strip with.

What is your basis for that statement? Loss of beading? As the OP notes we've been down this road before.

Re: Debate Over LSP Removal Settled
Great write-up! Being somewhat new to this, I read D114 at ~10:1 strips LSPs. That still a viable option?

Ha ha, I don't remember whether that got settled (with D114). Being that rinseless washes are touted to have lots of "polymers" in them, I would suspect that a high concentration of rinseless wash would provide a lot of polymers for masking beading and giving the illusion of stripping.

I've been fairly successful with 5 gallons of paint thinner. No dilution..... Takes it right off! I'll even load it up in my foam gun.

How did you know the LSP was gone? Did you spray with water and check for beading? If so, did you then wipe it down with IPA and then spray with water again? Usually whatever soap you are using leaves surfactants behind that destroy any beading, but once the surfactants are removed with IPA the beading returns if the LSP is still there.
