What Causes Meat Grinders To Rust?

Meat grinders are made of different materials. When the iron in these materials comes in contact with oxygen and water, it causes the metal to oxidize and rust.

Apart from that, it also renders the metal weak, making it rust over time. Once you discover that your meat grinder is becoming rusty, the next best thing is to act fast to stop that rust.

Step 3: Washing And Brushing

Once each part is thoroughly soaked, you'll want to brush them quickly to take the dirt or rust away from the parts and prepare them for the next step.

Take out one part at a time from the bowl. Gently brush and pay special attention to the meat grinder's blades.

Depending on how bad the rust and dirt are stuck on your equipment, you might want to repeat steps 2 and 3 until you're sure your old meat grinder is completely clean.

Step 4: Rinse And Dry

Once you're sure there are no longer grits or stains, you can give each part a good rinse. Then, finish it by wiping the grinder and all its parts with a clean, dry towel and allowing them to air dry.

Painting And Staining

Repainting the body will make your grinder look as good as new and protect it from oxidation, and staining the wood handle will prevent it from rotting.

Step 1: Preparation For Painting

Once your meat grinder is dried, the next step to take is to prepare it for painting. Cover the areas that should not be painted by taping paper around them.

Don't forget to cover the inside of your grinder so that paint doesn't get inside.

Step 2: Priming The Surface

Priming will help the coating adhere perfectly to the steel surface, provide extra protection to the steel, and make them durable.

Since your grinder will be exposed to moisture, avoid using latex or water-based undercoats. Instead, use a food-grade acrylic primer for safety and better adhesion.

Step 3: Painting

Once you've primed your metal, you can spray at least two paint coatings.

Three coats are recommended for optimal paint utilization. For cast iron painting, go for acrylic epoxy paint since it adheres best and lasts longer over time.

It is also best to use a primer and paint of the same brand for the best results.

Step 4: Sanding And Staining The Wooden Handle

Sand the handle with a rough sanding tool. Then stain the handle and coat it with food-grade conditioning and finishing oil.
