Aluminum is a metal that has been used for many years. It’s inexpensive and can be formed into any shape or size. The downside to aluminum is the fact it doesn’t have a natural shine as other metals do, so it needs to be polished regularly in order to keep its luster.

This post will provide you with 3 easy steps on how to polish aluminum.

Step 1: Clean the Aluminum

Cleaning aluminum is not too hard, but it does take some care. You can clean the entire surface with a wet rag or sponge and dish soap mixed together if you want to get really thorough about cleaning.

If you’re having trouble getting rid of the stubborn dirt, try using a screwdriver or stainless steel wire brush. Make sure that the surface is dry before wiping it down with an abrasive cloth for final cleaning steps to avoid rusting later on.

Step 2: Sand the Aluminum

The first thing you should know about sanding is that it’s a crucial part of many projects. If we don’t remove the excess material on our project, then there will be imperfections such as scratches and dings in places where nothing was before.

Starting with the coarser grit sandpaper, and working your way down to finer ones will allow for better control of what type of abrasion is needed on the aluminum.

There is no one set of rules when it comes to sanding. You will work from the lowest grade which would be 220-320 grit sandpaper depending on how the aluminum and works upwards until you have deep scratches or gouges sanded out with a finer grit for more vivid results, finishing off at 600 grit sandpaper.

When you’re sanding and shaping aluminum pieces, keep in mind that smaller projects can be done with just a little elbow grease. However, as soon as your project gets bigger or more complex – those big old hands are going to get tired real fast!

The best way to get through a big aluminum project is with an orbital sander and PSA discs or angle grinder. You’ll need some patience, but these tools will help you speed up the process so that your day isn’t wasted by sanding all morning long without getting anything done.

Step 3: Polish the Aluminum

For Smaller Polishing Projects

To take care of pesky tarnish, start by applying a small amount of aluminum polish to your surface. Continue wiping it into their surface with small circular motions and use either a clean cloth.

Are you polishing anything that will have food on it? If so, don’t use aluminum polish! It can be dangerous if ingested. Instead, opt for a homemade DIY compound made up of equal parts water and cream of tartar (potassium bitartrate).

For Smaller Polishing Projects

When you get to a job that could take a long time by hand or require too much elbow grease, there are always ways for power tools can help.

If it involves polishing the surface of your aluminum, then one tool most commonly used in this process is an angle grinder with airway buffing wheels on them.
