Original Ballcap Buddy Cap Washer (BLACK) by Sundance Sales

Product Information

Most baseball caps made in more recent years tend to have a plastic insert in the bill, which means they're a bit more durable and usually machine-washable, too. You can clean them with just about any method, but read the label first to ensure there aren't any special instructions. This is especially the case if the hat's primarily made from leather or suede. When washing a hat with a cardboard bill, avoid submerging it in water as the moisture will permanently damage the bill. Pro tip: you should only spot clean hats that have cardboard bill inserts, which are usually ones that were made in or before the eighties. Pat down with a towel to remove excess water. Be gentle to avoid tampering with the shape of the hat.

Although other methods work, the best approach may be to just hand wash your baseball cap. This way, you can be sure the hat maintains its shape and colour over time.
