We know that general metal and iron products are rusted, and they can be removed by physical methods. However, if the surface of the iron product is not flat, physical methods are more difficult. For example, for a meat cutter with a spiral shape, we can't grind the rust in a simple way. Here are a few convenient methods for your reference:
1. Stir with the fine sand and yellow mud appropriately, put it in the meat cutter to stir, and let the fine sand and yellow mud remove the rust in the meat cutter. But be careful not to install the blade, otherwise the blade will be damaged. 2, you can go to the store to buy some rust spray, spray to remove the rust. However, this method cannot guarantee that the rust removal is non-toxic and can be cleaned up.
