Dealing with water staining in aluminium

Aluminium is one of the most popular metals in industrial fabrication. The metal is a favourite because it is portable, malleable and does not stain or corrode easily. Aluminium is therefore used in a variety of applications ranging from the manufacture of aeroplane parts, building and construction materials to kitchen utensils. However, aluminium tends to get water staining when it is not properly stored.  Water staining appears as a white and powdery substance which forms on the surface of the metal. Even though water staining does not ruin the metal, it affects the appearance. In case you are planning to buy or store large amounts of the metal, you should follow the tips below to protect it from water staining.

Proper storage

In case the metal was delivered wet, or it got wet somewhere along the transportation process, you are supposed to wait till the metal dries up thoroughly before storage. You can also actively dry the metal through evaporation or the use of dried up air. When the moisture is removed from the metal, it prevents the growth of further stains on the metal.

Removing the existing stains

The stains that have already formed can be removed using different materials. In case the stains are newly formed and haven't affected the metal a lot, it is best to use a brush to clean it up. On the other hand, if the metal has large stains, you can remove the stains by dipping the metals in either sulphuric or chromic acid. The concentration of the acid should be low to avoid eroding the metal further.

Using the right cleaning solutions

While it is true that the best way to maintain aluminium in its pristine condition is to clean it regularly, it is also essential to make sure that you use the right cleaning agents. Cleaning solutions such as water and mild soap will not have adverse effects on the metal. However, solutions such as abrasive wax and abrasive cleaners might scour the surface of the metal and tarnish its appearance.

How well you maintain aluminium determines how good it will look, and how long it will serve you. It is best always to follow the instructions which they offer on cleaning and general maintenance of the metal. Following manufacturer's guidelines will reduce the possibility of ruining your metal and increase the length of time and quality of service the metal will deliver to you.
