Tool Cleaning Block - Medium grain

Cleaning blocks are great for removing rust, pitch and other gunk of off your bonsai and garden tools. They come in three grades, and each has its uses: We recommend the course for tough old rust and gunk, the medium for lighter cleaning and the fine for polishing. Because of their 90-degree edges, they can fit into hard to get to spots on your tools. Size 3" x 1.8" x .75"
