  • Just add water...
Size: 128 Fl Oz (Pack of 1) Style: WATERMELON
So many reviewers mentioned it doesn't foam well, not sure how they achieve that result (it would take some talent to NOT get suds from this stuff) , The one person who wanted this to wash their car without touching it.... not sure what expectations they had. I mean imagine taking a shower and being sprayed with soap with no scrubbing, especially the groin or armpit areas, wouldn't feel so clean. Anyhow, as a person who has been a detailing enthusiast/nut dealing with high end luxury cars for near 20 years I assure you this product does the job with almost a gratuitous amount of suds, which is never a bad thing as that quality prevents the dirt and particles from scratching the car's finish in the process of washing. This soap's foam is unparalleled. The soap is also really nice smelling, very much akin to real fresh watermelon, not the artificial candy type. Note there is no wax in this soap (a good thing for me, since soap + wax combos are truly poor attempts to merge products that should be at opposite ends of the car detailing process). If you like to properly maintain your car, this soap will definitely get your car clean and ready for the clay/polish/finish/seal or wax that should follow a car wash. Since it is high foaming it's a really good value as well, a little goes a long way. In my several uses of this soap, I would have a really difficult time believing this soap "doesn't foam" enough whether you are a two bucket person or a foam gun/pressure washer person. Good product, good value, and one of the best car care brands out there. ... show more

  • Great snow foam, but only a snow foam
Size: 128 Fl Oz (Pack of 1) Style: WATERMELON
I've been using this for quite awhile, either the honeydew or the watermelon. Both work great. Now here's what I have to say about it as a soap: Pros: Lots and lots of suds. I also use an MJCC former modified w a smaller orifice. Smells great Good at taking off easy contaminants stuck on paint, ex: dust, sand, tiny pebbles Great for getting into tight spots, wheels wells, multi spoke wheels. Looks cool, people will stop and ask what you're using. Cons: Not a soap to use in a handwash. Doesn't seem to have much dirt removing power. Overall, this is a good prewash product, if you're inbetween washes w minimal dirt, you can shoot this and spray off with no issues. My pics don't do much justice as they are from after letting the soap dwell for a min. It comes out much thicker. Always let it sit for a few mins then rinse soyou get the major contaminants off. ... show more

  • Value for money??
Size: 128 Fl Oz (Pack of 1) Style: WATERMELON
I like this soap. It's a good soap but I'm telling you. It ain't worth the money. I remember in 2021 I paid $20.99 for this. Now it is 44 bucks. That is more than double the price in 5 years. It ain't worth it
