Chem Guys Clean Slate Quick Review

Bunky

Detailing Gnosis
I was doing my fall detail and decided to try Chem Guys Clean Slate to see if it would strip old waxes and sealants as advertised. I actually was not expecting complete removal but looking to see if it was a "strong wash" to clean better than the average soap. I prefer stronger cleaning since I often retop the LSP often anyway.

The directions state 1 ounce to 5 gallons but I have never believed the dilutions on the bottle based upon prior experience with CG soaps so I used 2 oz to 4 gallons.

The car had about a 3 to 4 week coat of Pinnacle XMT 360 Spray Wax so it still shed water fairly fast. As a note, since I was prepping the car for a refresh, I also cleaned all the emblems with P21s Total Auto Wash using a brush BEFORE I washed it.

Observations
Scent: citrus
Color: yellow green
Suds: Decent suds with my well water (ph 7, 5 to 7 grains hardness so hard water) - I have had it tested 3 times so far in prep for a water softener installed.
Lubricity: Very good
Basic Cleaning: No complaints but car was not that dirty for a true test
Water spotting: Minimal
Rinsing: Easy
Wax/Sealant stripping: Nothing noticed


Conclusions
I did not notice really anything negative during the wash (foam, cleaning, easy to rinse). When rinsing I did not see any change in the sheeting characteristics except I will state the areas cleaned by P21s TAW sheeted very slowly compared to all other areas of the paint indicating a change in surface behavior. Had the Chem Guys soap left anything on the paint, I would have expected uniform sheeting on all areas and the wash should have removed any residue of P21s TAW if there was any. Based upon this, Clean Slate did not have any obvious affect on the LSP.

I also had some bug remnants on the front facia and they were not removed during the wash process and used PB`s Bug Squash to remove those after I dried it.

In saying this, of all Chem Guys soaps I have used (Mr. Pink, CW&G, Synthetic Body Wash, Honeydew, Maxi Suds) this was the best balanced Chem Guys soap I have used. I did not use it in a foam gun or cannon and will save that for a later review.

I know there has been a lot of discussion about stripping soaps but until I see warnings on product labels similar to APC such as use gloves, do not let dry on paint, work in small sections, etc. I cannot believe these soaps are that potent.

I did get a sample of Adam`s Paint Stripper and did a quick sniff test. The Adam`s has a much stronger chem smell and may try some side by side later.

In summary, if we ignore the claims about stripping, in my first use (usually takes 3 to 4 washes in different conditions to develop full opinion), it was one of the better Chem Guys soaps. I just cannot state how well it really cleans (versus stripping) until I did a better challenge.
 

Thanks Al.


This just reinforces what most of us already know and belive. Soaps in general don`t strip waxes anymore.


I do wonder though what it would do at a 1oz:1gal ratio.


 
Thanks for the review. So do you think that if it were washed multiple times it would work?
What would be good to use then?
 
Bunky:
This is EXACTLY the (unbiased and honest) review by fellow Autopians that I look forward to reading in this forum. I LOVE that fact that you compared this soap to a plethora of other Chemical guy`s soap that you have experience in using is invaluable information that we can all use.

I also like the comparison to Adams Strip Wash. someone has mentioned in a review of Adam`s Strip Wash that Chemical Guy`s makes/manufactures Adams products. I have no verification of this claim, BUT the observation that these two soaps are SIMILAR in color, smell, purpose, AND timing of release for sale to the general public seems more that "coincidental" to substantiate that claim.
Regardless, I think ALOT of professional and hobbyist detailers are looking for a quality wash soap that will prep vehicles by removing "older" (a key term) wax or sealant LSPs rather than using a 3-step decontamination wash (ValuGard`s or Finish Kare`s) OR using a strong APC (Optimum`s Power Clean or P21S Total Auto Wash) along with car washing soap.
Even if this wash doesn`t clean of LSPs completely, it may have applications for washing and thoroughly cleaning very dirty `daily driver" vehicles that owners/detailers wash on regular basis and then apply as spray-on wax or gloss-enhancing quick-detailer.
 
I also cleaned all the emblems with P21s Total Auto Wash using a brush BEFORE I washed it.

Using P21S TAW instead of your main wash soap to clean off emblems with a brush is interesting. Do you find TAW cleans intricate areas better than car wash soap + brush (or APC) alone? I never thought about using P21S TAW as a pre-treatment before.
 
I have always treated P21s TAW as a paint safe all purpose cleaner like a spot cleaner on emblems, grills, jambs, crevices, etc. It has some clinging characteristics so it can dwell a little on vertical areas. I always considered it strips wax as in the case above. It seems more like Optimum Power Clean but not sure if they are chemically related.
