I pumped a small line of foam along the inside band of my black cap and worked it in with the blue towel. It lifted a surprising amount of grime without soaking the whole hat.
The brim had picked up dust from daily wear. I used a little foam and wiped in the direction of the fabric, and the cap looks fresher without losing its shape.
My garage cap was pretty grimy around the band. It took two passes, but the no-rinse foam loosened the dirt and the included cloth handled the cleanup well.
I cleaned a white cap right at my desk and did not need a sink full of water. I used less foam than I expected and let it air-dry overnight.
My son's red cap gets sweaty after practice. The foam made it easier to clean the inner band, and I liked not having to put the structured brim in the washer.
I used it on a light gray golf cap and the band cleaned up nicely. The first pump was more than I needed, so next time I will start with a smaller amount.
I packed the bottle and towel for a trip and cleaned my cap on the hotel desk. It was simple, low-mess, and the hat was dry by morning.
Pumping the foam into my palm first helped me dab exactly where I wanted it on the brim. That kept the rest of the cap from getting too damp.
I focused on the sweatband and could see the grime transfer to the towel. A second wipe with a clean section left the inside feeling much better.
I cleaned two caps and left them on a towel to air-dry. Since they were never submerged, both kept their normal crown and brim shape.
The olive cap had dirt across the front after yard work. I brushed off the loose soil first, then used foam and the towel for the remaining marks.
The red cap was darkest right along the brim edge. Working slowly with one corner of the cloth cleaned that area without wetting the cardboard-like brim too much.
I tested a hidden spot first, then cleaned a makeup line on the inside of my beige cap. It took patience, but the stain is much less noticeable.
I used this on an older mesh-back fishing cap, especially around the band. It did not make the hat look brand new, but it removed the stale, dirty feel.
The inside of my child's blue team cap needed attention after a dusty game. The foam and cloth handled the band well, and I let the cap dry in the garage.
I cleaned my black workout cap on a locker-room bench and packed the bottle back into my tote. It is much easier than carrying a wet hat home.
I wiped around the stitched logo instead of scrubbing hard. The burgundy fabric cleaned evenly and the embroidery still looks crisp.
A small amount worked along the curved edge of my navy brim. I had to repeat one oily area, but the controlled foam kept the job manageable.
I cleaned a youth cap at the picnic table right after practice. Loose dirt came off first, then the foam handled the sweaty band without a full wash.
After wiping my gray cap, I set it near an open window on a towel. It dried evenly and did not come out misshapen like it sometimes does after washing.
