Just wanted to offer a brief review of the Four Star Platinum Series Ultimate Auto Wash Shampoo (whew! That's a mouthful. I certainly won't be the one to call it FSPSUAWP, but that's what it is).
First off I want to thank Dwayne from Four Star for providing a sample to test. Thank you!!!
I didn't do a side-by-side comparison with a competitor so I can't provide "punch stats" for things like lubricity and dwell time. Recently I've been using Blackfire shampoo and have used in the recent past Eagle One's shampoo (in that hot pink color) and
Pinnacle's shampoo. I also have lots of experience with Meguiar's #00.
Four Star starts off on the right foot with the fragrance - pina colada. It's quite noticeable on initial foam up and smells great. Color out of the bottle is a light grape purple, but of course becomes the typical white as it's mixed with water.
Speaking of foam up, Four Star shampoo provides a very nice and dense foam, very similar to foam on a capuccino

. The foam has excellent sustainability which is a critical feature IMO. Many
car wash shampoos foam up nicely when first mixed but lose their stamina before the wash is done. It's been my experience that some shampoos that foam up in large, fluffy bubbles do not last the wash cycle. But the foam in Four Star was nice and firm. Foaming is very important for lubricity and staying power (which I mean as the ability for the shampoo to remain on the panel instead of running off before rinsing). I feel this is the product's best feature.
Cleaning power was equal to the mentioned competitors. My car had gone two weeks between washes but was not extremely dirty. My car didn't need excessive rubbing to remove surface dirt.
Four Star rinsed clean with no residual and no streaking. There were no water spots left by the shampoo.
In summary, I feel Four Star's shampoo is an excellent product and I recommend it.

I know almost all Autopians have their favorite shampoos but if you're looking for something new, give Four Star Platinum Series Ultimate Auto Wash Shampoo a try. And in the future perhaps the folks at Four Star will change the name to something simple like Platinum Shampoo and we all can call it PS.
Hmmm, I guess this review wasn't so brief after all.
