Thread: Cleaning Aluminium

The Allibrite works fairly well. Now I thought that they changed the composition as I am sure that last time I bought it, it no longer had hydrofluoric Acid as part of its make up, but have just checked the MSDS and the composition is:
Water app 70%
Sulfuric Acid app 10%
Hydrogen Fluoride (which is Hydrofluoric Acid) app 10%
Ammonium Bifluoride app 10%
In these quantities reasonably safe but still present and a risk. See the thread on Hydrofluoric Acid.
Will have to check the container I have in the shed at home.
