bleachable

Let me make it clear that I am not talking only about such obviously bleachable surfaces as dirty grout, shower curtain liners or white T-shirts ambushed by drips of chocolate ice cream.

A rendering process yields a fat commodity (yellow grease, choice white grease, bleachable fancy tallow, etc.) and a protein meal (meat and bone meal, poultry byproduct meal, etc.).

The material may be an ion-doped crystal like Cr:YAG, which is used for Q-switching of Nd:YAG lasers, a bleachable dye, or a passive semiconductor device.
