cleaning steel bright after silver soldering.

[RRMBKParticipant @rrmbk]

Anyone got any tips for cleaning up steel to a bright finish after silver soldering.

I dunk in pickle( drain Cleaner) and then in clean water, cleans the flux off but leaves a dull grey / black finish on BMS. Is elbow grease the only answer and if so what abrasives do you use and how do people clean such stuff as small sharp angles, radii and corners please.

Have tried citric acid also but similar dull finish after pickling.

Many thanks

B.K.

Hi Brian,

Most chemical cleaners seem to have this effect.

It's down to elbow grease and a file I'm afraid.

Is sand blasting a viable solution for you?

You may find Garryflex blocks useful. They are rubber blocks impregnated with abrasive. I suggest the medium (grey) or fine (brown). You can cut these with a knife to get a suitable shape for nooks and crannies.
