A good snow foam is essential for your car detailing. The best products have the ability to remove far more dirt from your car before you’ve even had a chance for a contact wash. The reason why this is essential is because it reduces the chance of you damaging paintwork during the contact wash stage. Here, I’m putting the W4 Citrus Foam from Gtechniq to the test to see how well it performs and whether you should add it to your collection.
How I Tested Gtechniq W4 Citrus Foam
First of all, I used a cotton pad to perform a swipe test to get an idea of how dirty my car was before. I then applied W4 Citrus Foam via a snow foam lance. I followed the instructions for both dilution and dwell time. I then rinsed it off and performed another swipe test in the same area to see how much dirt was left.

First Impressions
Gtechniq’s packaging looks pretty science-y, which I’m sure is a technical term. Open the lid, and you are greeted by a gorgeous citrus scent. That might not help it clean any better, but let’s be honest, we love nice-smelling detailing products. And it immediately makes you want to get some W4 Citrus Foam in your foam lance.
Citrus Foam Features
Gtechniq’s W4 Citrus Foam snow foam is a coating-safe pH-neutral formula. Generally speaking, pH-neutral pre-wash products simply won’t be able to clean as well as more alkaline solutions. However, W4 Citrus Foam has a secret ingredient up its sleeve. It combines a citrus degreaser with a foaming agent, which gives it an extra kick. You can use a citrus pre-wash before applying snow foam for superior cleaning. By integrating it into the snow foam, Gtechniq has upped W4 Citrus Foam’s cleaning power significantly without making it more alkaline. And by keeping it pH-neutral, that means it won’t degrade any wax or coating you’ve got on your paintwork.
What’s It Like To Use Gtechniq W4 Citrus Foam
W4 Citrus Foam comes out of the snow foam cannon looking a little watery, but that’s never a reliable indicator of cleaning power. Despite not being especially thick, it does a good job of clinging to the bodywork to break down dirt and grime. I didn’t expect much from a pH-neutral snow foam, but, honestly, W4 Citrus Foam impressed me. The combo of citrus degreaser and foaming agent really helps it to shift dirt. It performed really well and did a noticeable job of removing dirt on the car. Using Gtechniq’s recommended dilution ratio, you’ll get 10 washes out of a 1-liter bottle, so that’s not bad at all.
Verdict
Gtechniq W4 Citrus Foam snow foam is a very strong offering. Its cleaning power is surprisingly good, much better than I expected. It’s reasonably priced, and you get a decent number of washes per bottle. And being pH-neutral, your coatings are safe. It smells great too. This is a snow foam that’s very easy to recommend.
