How do I clean aluminum panels

Clean the aluminum sheet

Aluminum can be found in many areas of life

Aluminum occurs in many areas in the home. Frames, decorative panels, but also pots and other objects are often made of aluminum or aluminum sheet. There are also countless applications in which you would like to work or process aluminum as a DIY enthusiast, for example before painting aluminum sheet.

Cleaning aluminum sheet in the household

Aluminum objects that you use in your household can be cleaned in different ways. However, exclude the cleaning agents and utensils that could damage the aluminum:

  • Scouring milk
  • Swab
  • Wire brushes or other very hard cleaning brushes

Also note the special features of aluminum when cleaning

Aluminum is a soft metal. As a result, it can be scratched very easily. Therefore, the mentioned aids are not to be used. A conventional washing-up liquid, which has a fat-dissolving effect, helps against grease on an aluminum sheet. If you want to remove limescale stains, you can use lemon juice or vinegar. Aluminum that is rubbed with lemon juice also brightens up again.

Successfully clean heavy aluminum soiling

A trick with aluminum parts that are heavily soiled, for example on vehicles, would be to use oven cleaner. Alloy rims or anchor plates that come into contact with hot brake dust can be cleaned in this way. To do this, the oven cleaner must be able to act for several hours.

Cleaning of aluminum sheet before further treatment or processing

The cleaning of aluminum sheet looks a little different if you want to work on something further, for example before painting. Aluminum ages; a certain patina forms due to oxidation. This must be removed before further editing.

Consider appropriate grain size

In particularly massive cases, use sandpaper with an appropriate grain size (never too coarse). An abrasive fleece is ideal for removing a relatively harmless oxidation layer. The abrasive fleece can also be used before polishing aluminum sheet.

Remove grease after cleaning

Then the aluminum sheet is not only cleaned of grinding dust residues and other dirt particles. In addition, you have to loosen any grease residues that could not be removed by the abrasive fleece. For example, if you were still touching the aluminum sheet with your hands while grinding. You can use commercially available grease and silicone cleaners for this.

If you have been able to remove grease residues from the aluminum sheet, please do not touch it with your bare fingers if you want to process the aluminum further. Because grease gets back onto the aluminum sheet via our hands.
