Gyeon Q2M Foam
The Ultimate Pre-wash for Coated Cars
Pre-washing, especially on cars where a paint correction has been undertaken, is very important to preserve the best possible visual effect for a longer time. Q2M Foam ensures a highly effective first step in the cleansing process as it helps to decrease the amount of dirt that needs to be removed during a proper, major wash with a mitt and shampoo.
A thick foam is one of the major benefits of high quality snow foams. Q2M Foam builds up a very thick and deep foam, sticking to dirty areas of the paint and dissolving dirt and grime. The foam should be washed away by a pressure washer before it starts to dry.
Most active snow foams affect coatings or protective layers (waxes) either by being strongly caustic or leaving a thin layer that can destroy their protective and self-cleaning properties. After diluting, Q2M Foam is totally safe for paint or even polished aluminium. It does not leave any residue after rinsing.
Q2M Foam provides the opportunity to have a home-made touchless wash. It dissolves gime and road-dirt, ensuring a gentle wash afterwards. Hence it's characteristics - it not only is totally safe for your coating, but also for uncoated cars or surfaces like polished alloy rims or exterior trims.
1:5 to 1:15 Dilution
Q2M Foam is very effective, it dilutes even 1:15, giving great value for money. To keep the foam fully effective, the minimum dilution is 1:15, but in the case of very dirty vehicles or uncoated ones, it is advisable to use in a proportion of 1:5.

Picked up a 4L jug of Gyeon Foam during last November’s TURKEY20 promo, finally got around to putting together the pressure washer/foam cannon setup to give it a try. Generally use at a 1:10 dilution ratio (1:15 works well too) which brings the cost down to about $2 per wash, well within the realm of practicality using the full 32oz capacity of the cannon reservoir bottle. Could likely cut this in half as 16oz of mixed solution will cover an average car nicely, but may as well really cover it, no?
As a hobbyist, didn’t really need a gas-powered pressure washer so I’m using a SunJoe SPX3001 electric pressure washer (2030psi/1.76gpm/14.5 amp) and at first was using a Dusichin SFL-001 Foam Cannon. It worked quite well, covering the car in a nice, aqueous solution of foam, which clung to the car long enough that it met the recommended dwell time (5 min max) before rinsing. While the thick, rich, shaving cream density foam may look nice, I prefer a more ‘wet’ solution; as long as it’s clinging to the (coated) surface for the proper length of time, I’d prefer the foam contains as much water as possible, figuring it’ll help it soften/carry away any dirt on the surface.
The SFL-001 was a nice cannon given the cost but required cranking all the way to max product used to produce the foam I liked at the dilution/consistency I prefer. It also kinda deteriorated in foam quality after about 10 washes, requiring disassembly and cleaning despite having clean water w/ a bit of APC run thru it after each use. Tried another cheapie foam cannon (MATCC) with much the same results; works well enough but still required max product used on adjustment dial to get desired results at 1:10.
Enter the MTM Hydro PF22 Foam Cannon. Now this thing, while a bit more pricey, produces excellent foam with Gyeon Foam, with room to spare on the adjustment dial. We’ll see how it holds up over time as I’ve only used it 3 or 4 times so far but initial thoughts are quite positive.
The foam itself from Gyeon works quite well in dissolving/washing away debris. We’ve had some strange environmental condition in our area this year where cars left outside often end up with almost a sugar-granule-like deposit on them the next day. It’s ‘persistent’ enough that on a windshield, wipers and washers won’t remove it and on the paint, a mere strong hosing down won’t remove it all either, but rather smear it all about. Using the Gyeon Foam during the prewash completely dissolves these debris easily, leaving the surface smooth and mostly contaminant free before a wash mitt/sponge even touches it.
Considering all the money we’ve put into coating our cars, an additional $2 a wash is completely worth the added safety margin of using foam, and Gyeon Foam has worked well on the strange deposits, bird droppings, and leftover marks from ‘tree droppings’. And let’s face it, foam cannons are just plain fun. It clings well, with even more room on adjustment dial for thicker foam on the PF22, is economical, rinses off nice and clean and pretty much does what it claims to do. I could likely look around and find a cheaper alternative that might work as well or better or, maybe not. In any event, I *know* the Gyeon Foam works, it fits within my cost-benefit framework and (at normal dilution) it has no detrimental effect on coatings or coating boosters like Kamikaze Overcoat or Gyeon Cure that I’ve seen…so why keep chasing rainbows? Additionally, when first prepping a car for decon/compound/polish/coating, I’ve begun to use a Gyeon foam bath at a greater dilution (1:2) as ‘perhaps’ it helps strip off more than just a regular decon wash. I dunno, but at the price, it certainly can’t hurt. At that dilution stronger dilution I’m pretty diligent on not leaving on surface too long; not sure what would happen if I did but really don’t wanna find out either.
Another nice thing about the 4L jug (square-ish in shape) is that it fits much nicer on a shelf than a round container does, quite nice alongside 4L containers of other Gyeon products; jug pours quite nicely as well, always a plus. I like the product and I see it being even more useful as winter approaches here in NE Ohio; a quick foam bath on the occasional warm winter day might not be a total and complete car cleaning but it’ll be easy and reasonably comfortable. I’m guessing the Gyeon Foam will help with salt deposits in the winter as well, much more safely than caustic touchless car wash chems would. We’ll see…
An invaluable product that we will not do without. It simply makes washing cars soooo much easier. Wash mitts glide across vehicles as if freshly waxed.
I have only had a chance to use this soap once but I like the results very much. I am sure I will continue to use on a regular basis.
I recently purchased thus soap and I absolutely love it this is by far the best soap I have used.
