Finishing Copper foil Projects

What order do you clean/wax/patina?


A question with many answers.

Almost everyone agrees that cleaning all flux and oil residues are the first stage of finishing. Once the panel is rinsed and dry the stage is set for the finish. The solder is then cleaned of any oxidisation by using steel wool, brass wire brush or some other mild abrasive.

However the industry does not use any metal in the cleaning of any surface to be patinated. Never use abrasive or corrosive materials to clean solder lines holding glass.  The most aggressive cleaner used is that intended for fibreglass baths. Do not use metal or scouring pads when cleaning.


Again opinion differs on the order of processes:

Some wax the solder lines and polish before applying patina.

Some apply patina and wax afterwards.

Both claim success with their method.


Comments from industry indicate that the order is:

Clean

Patina

Protect
