Looking for an isopropolyn based drying aide (not a panel prep) which contains lubricants but no protection. I just want to wipe away any remaining soap residue/film left behind after washing and air-blowing the car. I feel that air-drying the car doesn't remove all the soap residue as towel drying, and adding an SiO2 or polymer based drying aide after, just traps the soap film and it begins to build up. I'd rather use an alcohol based drying aide which is not as a strong as a panel prep and contains lubricants to help the towels slide.
Is there an isopropyl based drying aide?

:laughing: So take you favorite non-wax car soap, use it to wash a clen clear wine glass at home, blow dry it and wait a few minutes, you will find a slight haze, even if it is the slightest amount. Adding an SiO2 or Polymer drting aide on top of it will seal it in, that's why I'm looking for an isopropyl basde drying aide, to get rid of that slight film and prevent build up.
I would guess the buildup you are seeing on your wine glass is polymers in the soap to assist in drying (or other parts of washing). I would argue that you are wiping off those polymers with your drying aid. I would also argue that even if you are not removing them, you are not "sealing them in" as whatever SiO2 product will not bond properly on top of that residue, and that the next wash will wash it off.
I mean you are sort of going around in a circle here, you have some residue that you are concerned about, then you want to remove it with IPA that has lubricants in it...aren't the lubricants going to leave a residue? And if that lubricant residue will be wiped off, then won't your wash residue be wiped off with your drying aid? Have you tried wiping your wine glass with a drying aid to see what happens? Or did you not really do the wine glass experiment, and this is all just speculation?
EDIT:
PS A few months ago TRC had a video with Adam Pitale (founder of Adam's Polishes) about pre-coating wipedowns, and he said it was a bunch of bunk, there was no need to use a "panel prep" as the carrier for the coating is solvent and will remove anything as you put it on. I'm not saying I agree with that, I'm saying here's someone who sells coatings who says that a standard process is unecessary. My point is maybe you are over-thinking this.
And also--since in your first post, you say that towel drying removes the residue you are concerned about, but you are not towel drying...but yet you want to wipe the paint with something to remove the residue...so you are toweling it anyway, so why not just towel dry the car in the first place--problem solved. Again, it could be argued that the residue you are seeing is something put in the soap to act as a "drying aid" while you are toweling it dry.

When i had coated a truck with mohs evo earlier this year, i got told later that something was wrong with the coating because after washing the truck, it had this oily residue left on the truck.
I asked what soap they used, and the response was duragloss, 902 was the# if i remember correctly. Or maybe it was a wash/wax soap? Cant rememeber if they make that.
Either eay i told him to use a different soap, its not the coating.

902 is the gallon of the regular (901) wash. I guess I've been on forums too long, we litigated all this stuff I dunno, 16-18 years ago? Car washes have foaming agents, sheeting agents, "gloss enhancers" etc. in them that are put in there for various reasons. The Meguiar's consumer washes were notorious for this, for clogging your wax/sealant and making you think whatever flavor of the month LSP only lasted a month (in time for a new flavor!).
If it wasn't 16-18 years ago, certainly by 11 years ago it was proven on this forum:
Sealant Test: PowerLock (+/-) BlackHole, Wolfgang DGPS, & BlackFire WD
LSP stripping
As to whether any of this surfactant residue "builds up" or gets "sealed in" as the OP suggests, I'll beg off at this point.
First off you have an amazing memory! Thank you so much for posting the links to those discussions from 2013! very informative.
As far as which soaps I've used, I've tried them all, except the car pro brands since their pricing is just not realistic.
Bottom line, after rinsing, all soaps leave a film behind, which ususally is wiped away with towel drying. But as I mentioned earlier, I'm blow drying my car and then following up with a detailer or drying aide which, IMHO is not removing the film, but rather masking it and the gloss agents of the drying aide hide the ever so slight hazing from the soap film. Hence the question if there is an alcohol based drying aide (not panel prep) which will help remove the soap film.
For anyone whoi wants to geek out on the tenacious properties of soap film, this is a great video with great technical information on the subject, if the link doesn't work you can just search for "soap film demonstrations" from the "flinnScientific" channel. https://youtu.be/52wVrtA5krY?si=UNFJG7HcxKq5_uYA
I do not know of a product like that exists.
Man you are in way to deep.
Best to just leave it be and enjoy the vehicle. As soon as you drive something its dirty in some form anyway.
