A quick bit of polishing.

The Pink Stuff and an old electric toothbrush works wonders on grimy bracelets.

It's pretty abrasive, and you need something kinder for proper finishing if you want a high shine. Vanish oven cleaning paste is another, but it's a bit more fierce. Tubs of both cost less than £1. I don't use them because they're cheap, I use them because they do a good job. Duraglit wadding is another good one for finish polishing.

If you want gloss a dremel can be used with a felt head and jewellers rouge.   

It's useful to have an ultrasonic in your arsenal too but I quite get how quickly it adds up to buy everything, for some the choice between an ultrasound and adding another watch is straightforwards.

Maybe I'll buy a £5 knackered thing to practice on first though!

Possibly a very good idea. The good thing about polishing by hand is you're less likely to make mistakes, or go too far, and if like me, who no longer has a workshop and does all this stuff from the comfort of an armchair, things that spin and whirl have a habit of splattering stuff on the nice interior decor, walls, ceiling, and nostrils, no matter how careful you are. :laughing2dw:

The intention was to show that it's not that difficult or expensive to polish stainless etc by hand with over the counter cleaning products.

here's another project,

unfinished brass bell for a friends clock, you can see the machining is still very apparent,

smoothed off with a medium grade Scotchbrite pad,

start polish with The Pink Stuff,

and final polish with Duraglit,

in total less than £3's worth of consumables for a decent finish, and about 20 minutes work.

 

Brass is easy to work with. Once you've got a bit of experience in polishing you can tell by the feel and sound of the polishing agent you're using to work with what ever you are polishing. Aluminium is by far the easiest to work with. With most non ferrous metals, the cleaner/polishing medium will turn black pretty quickly, this adds to the polishing ability as it is effectively forming a paste which in turn adds to the quality of finish. It's always important to practice on something first, and be careful not to go too far.

Awesome work on that bell, very impressive :thumbs_up:
