This Stuff Cleans & Brightens Aluminum
I tried several different products that claimed it would clean my 6 ft. long aluminum diamond plate tool box.  They proved to all be a waste of time & money.  This product was super easy to apply and the results were miraculous. I diluted it 4:1 and brushed it on with a wide natural bristle paint brush applying it several times over the whole surface then waited no more than 5 minutes and rinsed off with clean water and dried with a towel.  It leaves a slightly hazy finish because of the highly acidic ingredients not a 'polished' finish one would get using aluminum polish but for a toolbox that had never been cleaned in 25 years that was good enough. I have almost 3/4 of the gallon left so a little goes a long ways.
