I've got about 20 baseball caps and some of them were honestly embarrassing to wear anymore. Sweat rings around the brim, yellowing on the front panels. Tried throwing a couple in the washing machine once and they came out warped. This kit is way better! The foam doesn't soak through, and the brush is soft enough that I wasn't worried about messing up the fabric. Got through four hats in maybe 30 minutes and they all look great. Definitely ordering another foam can when this one runs out.

My girlfriend got me this after I complained about a stain on my favorite fitted cap. The foam does most of the heavy lifting I just sprayed it on, worked it in with the brush, and wiped it off. The stain wasn't 100% gone after one pass but after a second round it was barely noticeable. Only reason I'm not giving 5 stars is the brush feels like it could be a little bigger, but it does the job. Hat dried fast and didn't lose its shape. Solid kit overall.

I collect vintage snapbacks and I'm super careful about what I use on them. This kit is gentle enough that I felt comfortable using it on a couple of older hats I'd been afraid to touch. The bristles are really soft and the foam doesn't leave any residue. Cleaned up a white New Era that had been sitting in my closet for two years because of a sweat stain on the brim. Looks almost new now. Really impressed.
