What features are most important to you in a car shampoo?

[IID]

I can see my vote is not a popular one lol but,
I voted for Water Spotting Resistance but feel Hard Water Spotting would fit in this same category.Ridding a vehicle of water spots most times is a pain in the azz and is time consuming.
If i was able to vote for(3)categories,including my first choice to be one of my opinionated top 3:
I would also choose Lubricity to help to resist marr and scratching from dirt trapped in the wash media and/or from the media itself,depending on which wash media is being used.
Sudsing would round off my 3 choices because of the ability for the suds to incapsulate the dirt and debris and help carry it off and away from the vehicles surface.
These 3 choices should help maintain a corrected,swirl/scratch free finish,from needing future corrections Pre-maturely.

I think for the most part,quality(& half way decent)car shampoos clean well and have Good Cleaning Abilitybut if you needed to remove stubborn tar,grime,bugs,ect..-there are products that are dedicated to assist in these areas.
I would use my LSP for Slickness,Gloss/Shine,and Protect categories.

Rinse-abilityhas never been an issue with any of the dozen's of car shampoo's I use(d).

Obviously these are just my opinion's

I voted for: cleaning, lubricity, and rinse-ability.

Since you did not mention cost as a variable, I would note there are quite a number of soaps that meet all needs at all price points so you do not have to pay more to get a top performing soap.

Exactly my picks as well Al! And excellent analysis about cost. It's incredible to me what some people are willing to pay for a "soap" when you can get the best quality around for less than 0.50 per wash.

Todd, the price is very important to me and while inflating a price for exclusivity might work for a segment of people it doesn't for me. :inspector:

Chem Guys Glossworkz.....pretty impressive - good foam thru a gun and exceptional gloss....as I'm using it in a tropical clime and washing once a week, extreme gloss is my #1 priority...and this does it nicely...
