How To Remove Cement Stains From Aluminium

If you have stored aluminium sheets or machining bars nearby to where some cement works are being completed, you may look at your metal at a later date only to find that it has been stained with flecks of cement. These sorts of stains can be highly difficult to remove, as they tend to settle more quickly then other types of stains. It also has an etching effect on the aluminium, meaning that it can seriously damage the metal if not removed properly.

Whilst it is near impossible to completely remove cement from the surface of aluminium sheeting once it has set, there is a way that you can try and make the stain appear less noticeable:

Begin by filling a bucket with about 4 litres of water or a little less. Mix in about a quarter of a cup of laundry detergent (this will serve as your aluminium cleaning solution). Take a scrubbing brush and use it to apply the solution to the aluminium sheeting or machining bars, being sure to scrub in a circular motion for a minute or two. Leave your aluminium to sit like this for a maximum of one hour before rinsing it off with clean water. The cement stain should be less visible.

It is important to keep in mind that the above method will have varying degrees of success, depending on how long the cement has been left to set on the aluminium sheeting. For the best results possible, ensure that you clean the aluminium as soon as wet concrete has touched it. And, of course, it is always best to prevent these stains forming on your aluminium in the first place.
