Product Review: CarPro EcH2O


Traditional washing, rinseless washing, waterless washing…they all have one goal in mind, and that is to clean your car.  I use all of these methods to maintain my car depending on how dirty it is, and I love having a good waterless wash on hand for quick and easy clean ups when my car is not exceptionally soiled.

I was excited to hear about CarPro’s EcH20 Waterless Wash, which is their first step into the waterless washing market.  CarPro has formulated this product to work perfectly with ceramic coatings, like CQuartz, because EcH2O is packed with high end SiO2 hybrid particles.

I’ve been using EcH2O for a couple of months now, and it has provided excellent cleaning power, exceptional gloss, and a noticeably slicker feeling after use.  One thing I have noticed is this product does require a bit more wiping/buffing to remove residual product in order to produce a perfect, streak free finish, but after a few uses it started to feel more routine to me.

For more information and a brief demonstration of a waterless wash, check out my video review.

EcH2O is a very versatile product that allows you to easily clean and enhance your vehicle’s appearance in a quick and safe manner.  The concentrated product can be mixed for use as a waterless wash, quick detail spray, rinseless wash solution, or clay lubricant.

Quick Detailer:

  • Shake well and dilute 1:5~1:15
  • Spray, spread, and wipe off completely

Waterless Wash:

  • Shake well and dilute 1:5 up to 1:10
  • Spray liberally across one entire panel
  • Lightly wipe with microfiber towel flipping towel to fresh sides often
  • Spray once more across panel surface
  • Using a fresh microfiber towel wipe surface removing remainder of dust and dirt
  • Move to next panel, repeat steps 2-5, and continue around vehicle
  • Final wipe entire vehicle with a fresh clean towel as needed

Clay Lubricant: 1:40

Rinse-less Wash: 2oz per 3 gallon (1:200)

So if you’re new to waterless washing, or just looking for a versatile product to help keep your car clean, I’d recommend giving CarPro EcH2O a shot.

    What kind of durability can you expect from the SiO2 using it as a qd with a rough estimation? Also do I have to wash towels immediately after using this because of the SiO2?

    • Hi James – this product is not meant to provide durable protection. EcH2O is a waterless wash product that can also be used as a quick detailer. Like most quick detail sprays, the goal of EcH2O is to perform light cleaning and gloss enhancement. The SiO2 content in this product is very small. It will have no negative effect on your towels or wash media. Absolutely no need to wash immediately.

      Please let me know if you have any other questions

    Hey Zach,
    Great, honest review! You hit on a lot of points. Also appreciate the vid demo. Keep up the great work!

    Great review Zach! Have you had any experience with Ech2O and Reload on a single stage paint? I love this on cars with base/clear finishes but have a 69 GTO coming up and thinking this combo could really pop on the red paint.

    • Hi Rich – I’ve honestly only ever touched a handful of single stage paint jobs in my life. I have not used either EcH2O or Reload on single stage paint. If you get the chance to try it out, let me know how it works!

    I love the product but mainly use it as my “blue juice” detail spray. I mix it up at a ratio of 1:20, fill a 32oz bottle to the 27oz mark, then add 2oz of CarPro Reload and shake. Amazing detail spray.

    As a waterless wash I find ECH20 takes as you note, a bit more wiping, especially on my black cars so I stick with it as a spray and give my mixture to my customers who get a coating job done.

    My experience was poor. Wiped my CQuartz black car in the garage with clean microfibre for a quick detail. Pulled out of the garage to find streaks all over the car – never had that happen with any detailer.

    • Hi – can you elaborate specifically how you used the product? What was your dilution ratio? Did you spray directly onto the panel, onto the towel, both? How much wiping did you do? Etc.

      As I had mentioned in the article and in the video “I have noticed is this product does require a bit more wiping/buffing to remove residual product in order to produce a perfect, streak free finish, but after a few uses it started to feel more routine to me”.

    • Richard Beach says:

      My understanding is the product is designed to haze as it dries and then buff to a glossy finish. ECH2O has a small amount of protection in the product that creates this additional buff time. That said, it does take more time and effort than a normal detail spray.

      • Richard – you are correct on all accounts. After wiping the product, it is expected that the residue will leave a haze that should then be easily removed. I find that it works well to clean one panel, then work on another before going back to the first and wiping away the haze. Sometimes I will work on an entire side of a vehicle before going back to my starting point to wipe away to a clean finish. I’ve always found the haze to be quite easy to remove, revealing a streak free finish.

  7. Joe Maniwan says:

    Hey Zach,

    In terms and ease and finish, would you choose this product over Optimum No Rinse? Both products will be used as rinseless.


    • Hi Joe – For rinseless washing I personally use ONR most often because it works well and is very inexpensive. I have only used EcH2O once for rinseless just for experimental reasons, and it worked nicely as well.

    Hello Zach
    Could i use Ech2o as lubricant in synthetic clay mitt? Mothers for the Caly Speed 2 say no because its not water based!! Anyway may i use it in other clay mitts? I use except mothers and the Farecla Clay Mitt.
    Does Ech2o remove the applying wax/sealent when i use the Ech2o as waterless wash?
    Thank you for your time
