I thought I did a check list of car wash soap characteristics that are determine the viability and acceptance for Autopian use, but I could not find it, so I will do this from my memory:
1) Cleaning ability.
2) Lubricity
3) Foaming ability and how how long the foam lasts, because this determines if it "clings" to vertical surfaces
4a) Compatibility with hard water
4b) Compatibility with COLD water; IE, does it dissolve in cold water as I have in Green Bay, WI from my Lake Michigan-sourced municipal water supply.
5) Rinse ability; IE, does it rinse clean and leave little soap residue as it dries.
6) Fragrance, which might be important to someone who is fragrance-intolerant or allergic to certain chemical fragrances.
7a) Dilution ratio; IE, how much per gallon of water is needed to achieve its cleaning ability and still last
7b) Cost per ounce, which is hand-in-hand with dilution
8) Viscosity; IE, does it pour easily and is it easy to meter/measure out
9) Availability; IE, bought over-the-counter (brick-n-mortar store) or "boutique" (reseller/distributor/dealer/factory-direct) internet ordered.
10) Can it be used in the sun, which MOST soaps cannot (I avoid washing in the sun at all costs. NEVER had a good outcome by doing so with our hard Lake Michigan-sourced municipal water. Maybe if I used distilled/ionized water that would yield different results. I think the only car-wash soaps I know of that can be used in direct sun are Poor Boy`s World Super Slick-n-Suds at $45.00/gallon and McKee`s 37 SiO2 Wash Soap at $60.00/gallon, which are getting on the "pricey" side for me compared to Hyper Wash`s $30.00/gallon last I checked internet prices)
Judging by briarpatch`s report and experience with 3D Super Soap, it checks a lot of those boxes (characteristics) mentioned above. Is it enough to supplant or replace Meg`s Pro Detailer D110 Hyper Wash?
Let`s face it; we Autopians all have our car-wash soap characteristics that are most important to each one of us. From many Autopian experiences, I see CarPro Reset as being an outstanding soap, but it is more expensive to use. That might not be important to a hobbyist, but it is to a professional detailer or car-lot detailer who has to wash many cars a week.
