How to clean stamping grease off metal parts

Stamping is the product of a manufacturing technique that uses stamping dies to mass produce metal parts. Stamping takes a flat sheet of metal as raw material and passes it through a punch press, combined with a stamping die, to form the metal into the desired shape and size.

Stamping is a widely used technique because it saves welding time, energy consumption, provides dimensional accuracy, and reduces manufacturing costs. Stamping parts have a coating lubricant on the surface to prevent deformation and adhesion of other materials during the stamping process.

This coating remains on the stamping part even after it has served its purpose. In this article, we will discuss how to remove stamping lubricant from metal parts.

11 Ways to Remove Stamping Lubricant from Metal Parts

Using Solvents

The most common method used to remove stamping lubricants involves solvents. There are many available on the market, so you need to find the one that best suits your needs. Read the product label carefully and follow all safety instructions. Wear appropriate protective gear, including gloves and goggles, when using solvents.

Dampen a cloth with solvent and wipe the lubricant off the metal part. Always apply solvent to the cloth, not directly to the part, to prevent damage to the part. After cleaning stampings with solvents, rinse with clean water and/or soap as needed to remove any remaining lubricant from the surface of the part.

Using solvents to clean lubricants from stampings is a recognized method because they will not damage the parts.

Using Cleaners

Many types of cleaners can be used to remove stamping lubricants from the surface of metal parts. However, before using, verify their compatibility with the metal you are cleaning. Using the wrong cleaner may cause rust or damage to the surface. Then apply it to the dirty part and wipe with a cloth. Repeat the process until all surface dirt is removed.

Using Sandpaper

Stamping lubricants can be removed using sandpaper and paper towels. Wet the sandpaper and then wrap it around a rolled towel. Hold the towel at both ends so that the part stays in place while you wipe it clean. Rubber gloves can be used to prevent fingerprints. This method requires practice, but it gives better results than other methods in some cases. Solvents or cleaners can damage the surface of metal parts.

Using sandpaper or rewiping is an effective cleaning method to remove dirt from stampings without causing damage.

Sandpaper is also great for cleaning stains.

Using Ammonia

Ammonia is an excellent environmental choice. Apply it to a cloth and wipe it clean. Wear gloves and goggles when using ammonia, and avoid getting it on your skin or eyes.

Ammonia is an environmentally friendly cleaner that cleans many types of lubricants and oils from metal parts.

Using Brake Cleaner

Brake cleaner is another good choice for cleaning stamping grease from metal parts because it quickly removes most lubricants and leaves a dry, clean surface. To use brake cleaner, spray it on the part and wipe it with a cloth. Wear gloves and goggles when using brake cleaner, and avoid getting it on your skin or eyes.

Using Gasoline

Gasoline quickly dissolves stamping lubricants. Simply put a few drops on a rag and wipe the part. Remember that gasoline is a highly flammable fire hazard and must be used with caution. Good ventilation is important and must be practiced to prevent vapor buildup.

Using Kerosene

Kerosene can also remove stamping grease from metal parts. Use kerosene in the same way that No. 6 gasoline is recommended.

Kerosene is effective in removing ink and other stains from metal surfaces.

Using Lighter Fluid

Lighter fluid is another solvent used to clean stamping grease from metal parts. Use lighter fluid following the same guidelines recommended for gasoline and kerosene.

Using a Welder

Aluminum parts can be easily cleaned using a welding machine, which uses the heat generated by the welding machine to evaporate the lubricant. Do not overheat the stamping as it may damage the stamping face.

Welders can also be used on steel and other metals, but are most effective with aluminum.

Using Steam
One of the best ways to remove stamping grease from metal parts is to use steam or high-pressure steam. Make sure not to use too much pressure or you may damage the component.

Using an Ultrasonic Cleaner

This is a device that uses high-frequency sound waves to remove grease from metal parts. The sound waves cause the lubricant to break up into small pieces and be washed away.

Simply place the part into the cleaner and turn it on. The cleaner will automatically generate the correct level of heat and ultrasound required for cleaning.

Final Thoughts

The method you choose will depend on the type of stamping lubricant, the material of the stamping part, and the size of the stamping. Choose the grease removal method that best suits your needs. Regardless of the method used, it is critical that all safety instructions are followed.
