Product Review: CarPro HydrO2 Foam


CarPro’s HydrO2 Wipe-less Spray Sealant was a ground breaking product that really changed the way a lot of people protect their vehicles.  This revolutionary product simply requires the user to mist the chemical onto a wet surface, and then rinse it off with a strong stream of water.  Afterwards, it was protected for months!  I featured this product in a previous article about protecting your wheels called “Seal Your Wheels in Less Than 1 Minute“… it can’t get any easier than that, right?!  Well, CarPro has attempted to make it even easier by combining the features of HydrO2 into a shampoo.

The CarPro HydrO2 Foam, also known as HydroFoam, will allow you to wash and coat your car with protection in one easy step! HydrO2 Foam is a pH Neutral shampoo designed to gently lift and remove dirt and other contamination from your paint safely and easily. A special lifting lubricant was added to the formula, which not only allows dirt and grime to be lifted from the surface, but also provide a lubricant that allows your wash mitt to glide across the surface. This greatly reduces the risk of implementing new imperfections in the paint during the wash process! The rich foam cleans the surface with ease, but the other great feature of this wash is that it leaves behind a durable silica shell that produces a brilliant shine and protects your car from harmful uv rays, dirt, grime, brake dust, bug splatter, etc. Use HydrO2 Foam on your paint, glass, plastic, wheels, calipers, and wheel wells. If you are looking to clean and protect your car from harmful environmental contamination, the CarPro HydrO2 Foam is a great choice!

HydrO2 Foam can be applied by hand (without foam gun or foam lance) or with a Foam Gun / Foam Lance.  I chose to test the product out using our DI Foam Lance attached to my pressure washer.  I mixed 9 parts water to 1 part HydrO2 Foam as instructed and then proceeded to foam the vehicle.  When using the foam lance method, you should foam one section of the vehicle at a time, then wash that section with a wash mitt or sponge while the foam is on the surface, and then immediately rinse with water.  Continue doing this until the entire vehicle has been washed, then go back and rinse the entire vehicle again to ensure there is no remaining soap residue.  Also remember, it is very important that the vehicle remains in a shaded area and the panels are completely cool while washing with HydrO2 Foam.

I found the foam lance application method to work fine, but I personally felt rushed throughout the process.  Spray foam, wash panel, rinse panel, spray foam, wash panel, rinse panel…. There was just a lot going on.

When applying without a foaming mechanism, mix a solution of 9 parts water to 1 part shampoo into a spray bottle.  Spray shampoo solution onto a panel, or pour solution directly onto damp wash mitt.  Beginning at the top of the vehicle, wash one panel at a time, then immediately rinse with your hose afterwards.  Continue this process until the entire vehicle has been washed, then rinse the entire vehicle again to ensure all soap residue has been removed.

Once the vehicle has been washed and rinsed, the surface will be glossy and hydrophobic.  Water will bead up and roll off of the surface with ease.  Use this shampoo when you need to refresh your protection on your vehicle, or if you simply want to add additional protection on top of a sealant or coating.

If you’re looking for a true one-step process for washing and sealing your vehicle, HydrO2 Foam may be a real time saver!

    Great article Zach…Thank you. This has become one of my favorite protection products. I have used it in a foam lance and bucket method. Either way, a great way to add a layer of protection.
    Two months ago, I applied it to our old CR-V that sits outside 24/7. It still beads and protects like a champ. We have had rain and snow in that time, including the Blizzard.
    Another Car Pro winner!

    hi zach this site.can i wash my car the normal way and before drying spray this on and just hose it off? no washmit or hog hair brushing and just blow it off. thanks for your time…john.

    • If you’re going to do that, I would recommend using traditional HydrO2 instead of HydrO2Foam shampoo. HydrO2 is a stand alone sealant that is meant to be applied to a wet vehicle after it has been cleaned. HydrO2Foam is a combination of shampoo and HydrO2 so that you can clean and protect all in one step. Hope that helps!

  3. Great article and thank you for the write up. This product is excellent, but would stay away from the sun 🙂

    • Yes, we always recommend washing in complete shade when the paint is cool to the touch, but it is absolutely critical when working with HydrO2 and HydrO2 Foam as these products will cause a lot of trouble if they’re allowed to dry. Thanks for reading!

    Hows hyrdo2-lite compare…I like it because it already mixed and ready to spritz on then hose off…



  5. Rick Cimino says:

    HI ZACH,

    Can this then be dried off with a chamois or MF towel when completely rinsed?


    • Rick – yes, completely rinse the soap from the surface and then towel dry using a waffle weave drying towel. Do not allow the soap to dry on the surface… it is very important to work in complete shade and only when the vehicle is completely cool to the touch. If the soap dries it will leave streaks.

    Hydro2Foam + Griot’s PFM Terry Weave Drying Towel = Magic

    Hello Zach, I definitely want to try this product out, it looks amazing! I will just be mixing it into a wash bucket, but I am not sure how much I should add in? It says 1 to 9 but I guess I’m just not sure what is the best way to measure it. I watched one of the videos on it and the guy said to add and ounce and a half to a bucket of water..I’ll be using a 5 gal bucket. Does this stuff come with some kind of measuring cup? Any help would be appreciated!
