Sandblasting is a highly effective method of eliminating rust off instruments that does not need a lot of time or money. Old tools will rust over time due to exposure to air, water, and other factors. The fact that they rust does not imply that they must remain that way. Even if the tool contains wood, it may be sandblasted safely. The wood will get clean again, looking as good as new. The process works by blasting very small glass beads into the surface of the metal. The bead size should be no larger than 1/4 inch for optimal results. If used properly, sandblasting can remove any type of rust from any type of metal. It is very effective against creosote too! Sandblasting is also useful for cleaning off dust or paint overspray that would otherwise ruin a tool's appearance. This is an easy process that requires only a few supplies: a compressor, sand, steel wool, spray primer, and oil or lubricant. The compressor will provide the air pressure required to send the sand through the nozzle. You will need to clean both the instrument and its housing before beginning sandblasting. Use a wire brush to remove any rust or debris from the exterior surface. Then, use steel wool to get into tight spots where regular soap and water might not reach. Allow the object to dry before moving on to the next step.
