Black Oxide, Aluminum
Aluminum siding cannot rust and it's a very durable material, however there are numerous things which can cause it to oxidize. Oxidization can make aluminum siding look ugly which needs to be cleaned off as quickly as possible. There are many different things that you can do to clean this aluminum siding and remove the back oxides.
While aluminum doesn't rust there will be patches of dull white areas where the metal has oxidized. Removing aluminum oxidization from aluminum siding is actually pretty easy. It's even easier as long as you spend time preparing and getting all of the right tools that you require to complete the project.
Step 1 - Evaluation
The first thing that you will need to do is take a look at the problem you are suffering from. Aluminum oxidation is a major problem but there are different degrees of oxidation which can need different treatments.
Aluminum doesn't rust however it can take on a slightly dull and white appearance. The degree of the problem will affect the type of solution that you will use.
Step 2 - Dealing with Light Oxidation
If the oxidation is mild and light then you should be able to use an oxidation removal product without acid. This can be purchased in sprayable or paste solutions which are very easy to apply.
These are simply sprayed or rubbed onto the surface of the aluminum and then buffed up using a clean cloth. You don't need to actually use a power buffer however you will find it easier if you do. When using a power buffer to do this job you will need to use a clean pad regularly.
Step 3 - Dealing with Medium Oxidation
If you are suffering from a medium oxidation problem then you can use a slightly stronger solution. You can use the same product as a mild case of oxidation however you will need to put in a lot of effort, you should also mix the oxidation solution at the highest concentrations suggested don the bottle.
If the medium strength solution doesn't solve the problem then you can use more powerful solutions. Be very careful when working with the more powerful oxidation solutions because these are much stronger and can cause harm if not treated with respect.
Step 4 - Heavy Oxidation
If you are dealing with heavy aluminum oxidation then you will need to use a much stronger product. Many of these stronger products include acids which make them very powerful.
