For aluminum,I use a soft sanding then can be soft polished using "buhler" with a cloth

For those who want I can give some "advices " for steel and brass wheathering,I made some knives and japanese weapon accessoiries in the past,so I have found some ways to do wheathering on steel and copper alloys.
Generally I work with ammonia vapour for copper,displaying a refreshed piece in ambient temperature container with some ammonia on bottom,no contact ,only vapour actoin.
It will give a brown to black,with bluish or greenish accent depending on material.
It works better with bronzes,brass than pure copper.

For iron alloy I use acids,hydrochloric for stainless steel,can be used as vapour for a soft rusty look,or as liquid for tarnished grey look.
For non-stainless iron I use nitric acid,as a vapour,it takes a long time,but it will bring a full rusty color dark to reddish chocolate.
Then you can use wax to protect.
Other way is to heat the pieceand apply acid with a brush.

PLease don't forget the solutions are corrosive and nocive,and work with air,not in closed space,and use protections for eyes and hands.

Please remember we NEVER put water in acid,but acid in water.
