How to clean anodized aluminium actually not really difficult because, in simple way, it can be explained that you only need the materials you use while you are doing the electrochemical process known as anodizing, yet do the following steps in reverse order. Well, anodize finish might success to create a weather-resistant, durable, aesthetic, and cost-effective metal product because theAse are the answers on why you have to anodize metal. Unfortunately, by the time, the anodize finish will turn out as stained and dull, in general, in which you have to replace, or at least clean the surface. Yet, the cleaning process will not work well, instead of having a finish product as you mean, it will turn to be a drab-looking finished. That is why, to clean the anodize finish properly, you have to anodize the metal.
Reverse Order on How to Clean Anodized Aluminium
If you have already read about the step on how to anodize aluminium, and then you must have already known about the materials requirement. You know, such as the acid-base baths, passed through the electric current on both medium, cleaning steps, the right timing equipment, and so on. Thus, the process of de-anodizing aluminium can be explained simply by your logic, it is: do it based on the anodizing process, it means prepare the similar materials and all, but do it in reverse order. Well, sounds easy yet effective task, right? However, when you are about to de-anodized metal, you need to understand that not every metal can be de-anodized chemically, but only aluminium.
Prepare the Materials for Cleaning the Anodized Aluminium
As the only metal that can be de-anodized chemically is only aluminium, then make sure to use proper material to perform this task, and you need to prepare the sodium hydroxide as the magic chemical you only need. There are two forms of sodium hydroxides, the liquid form and crystal form, and based on most reviews, the most effective form used for de-anodizing is the dry crystal. Dry crystal form, in the other hand, also least expensive than another form availability. After that, you have to prepare warm water, gloves with rubber-made material, eye protector such as glasses or eye protection in specific, and also drain cleaner. Once the materials completed, you are ready to de-anodize the aluminium.
The de-anodize process begins with mixing the drain cleaner, approximately 1 tablespoon, into warm water where the metal surfaces can be covered well. When you are on this step, do not forget to make sure that air movement is visible on the pan and about to form bubbles. This process will produce chemical residue accumulated either known with smut. The key process is that you have to remove the smut, periodically, in order to let the metal surface exposed with the cleaner. The more you add the cleaner, the process is going to be faster. Once the metal has flat colour in scratches, you only need to rinse the metal with fresh water, and the dry it well. After all, that’s how to clean anodized aluminium in simple explanation.
