Cleaning Block - Coarse grain

Tackle stubborn rust and buildup with the Coarse Grain Cleaning Block, a practical maintenance accessory for keeping your bonsai tools in working condition. Its coarse abrasive surface is designed for more aggressive cleaning, helping remove surface rust, oxidation, and accumulated residue from metal tools.

Ideal for restoring neglected tools or performing occasional heavy-duty maintenance, this cleaning block is particularly useful when finer abrasives aren't sufficient. It helps prepare metal surfaces for additional cleaning and finishing, making it a valuable first step in a complete bonsai tool maintenance routine.

For a smoother finish, follow coarse-grain cleaning with a medium- or fine-grain cleaning block, then apply camellia oil to suitable metal surfaces to help protect against future corrosion.
