碎玻璃研磨介質，5磅

That finer dust stayed airborne longer than with other media I've tried, but it cut through the rust on my metal chairs in half the time. The five-pound bag was plenty for my small blaster.

Took off heavy rust and paint on a steel gate in one pass with my grit blaster, and the 5 lb bag lasted longer than I expected for the size. The crushed glass is sharp enough to bite hard but didn’t clog my nozzle once, which was my biggest worry.

The glass shards cut through years of baked-on grime on my metal parts way faster than I expected, and the 5-pound bag lasted through several full blasting sessions. Cleanup was a breeze since it broke down into fine dust instead of clogging the nozzle.
