That depends. Fiber-Shield® products have been shown under laboratory tests to outperform every other fluoropolymeric protector on the market. It's very durable! Fiber-Shield® will not wash out with cleaning, but it can begin to wear off with heavy use. Here's our rule of thumb: If your treated item has had enough use - enough abrasion - that cleaning is required, then have us clean it, and we will reapply the Fiber-Shield® protector at no charge.
