For those of you who use Mr. (or Ms.) Clean: what ratio to water do you use in the ultrasonic?

Came to ask this same thing. Would a tablespoon in 600ml of water do the trick?

Dawn liquid. One hefty squirt will do.

I use ultrasonic with hot water and denture cleaning tabs like Kukident or alike.

I think using distilled water instead of tap water is a good idea, if possible.

I use an ultrasonic cleaner too, but just use liquid soap - a soap I use to clean my prescription glasses as well, the kind that doesn't stick - it doesn't do anything deep but it does get the gunk out - It's the cheapest one from China, has a 50W program that can run for 30 minutes, after 10 minutes it gets super hot, so it softens the dirt well

After that I place the parts in front of a hair dryer in the hottest setting for 20 minutes or so, this in my opinion makes sure no water or humidity can stay inside the pins etc. - after both operations you can't touch the parts for a while

I wonder what can be done about rare corrosion spots

Once I left a bracelet soaked in WD40 for a while, shaked it from time to time, it cleaned the bracelet well too but I don't recall it doing anything extra

What do these spots look like?

Found one on a bracelet, and as a more extreme example have this on a case :/ It’d look better if it was possible to get rid of the rust coloring on the case



Don’t know how the case got damaged, but the bracelet damage is because that part was inside the clasp and likely held humidity

There's not much you can do with the pitting at home. If you can find some evapo-rust that may help get rid of the brown colour.

I like that dishwasher idea but if my wife finds out I run a whole cycle in the dishwasher just for a bracelet that will be a water use power use lecture. I could give it a shot but I might need to get the ultrasonic cleaner just to keep the peace.

For things you can do with a scrub-brush and hot water, you don't need ultrasonic. Mind you, they're not expensive, so worth a look.

I bought a $35 ultrasonic off Amazon last week and it’s worked like a charm so far. Definitely worth the cost to avoid that lecture @Walrus .

It does a pretty great job too. My vintage watch hobby has turned into a vintage bracelet hobby as of late, and some of the items I’ve picked up were downright filthy. While running the ultrasonic, I can actually see tendrils of grime working their way out from between the links. It’s kind of interesting to watch.

I would tend to agree with your wife. Is there any problem with washing the bracelet along with the cutlery?

Cleaned many a bracelet and Fish guts soaked NATO with a cheap lowest of pressure Karcher.

1) Just make sure you hold onto the side your not cleaning
2) Towel or piece of rubber underneath

Thanks, there's some Wurth / Winkel sprays here for sale - I might also check the watch repair industry in Turkey and see what their solution is, there's usually a solution, so far I've tried to ignore it and keep it original, but if it's possible to fill it and restore the original brushing, might be worth a try

My small advice for rust, it's best to first approach it with fingernails, the surface rust isn't that hard to remove and once the surface rust is removed, usually there's little to none penetrated rust underneath - fingernails also don't seem to mess with the brushing patterns

Sometimes it can be that stainless steel show some chemical reaction to acid so that some salts flock out - sorry for this unprecise description I`m no chemist 😉
Sometimes you can solve this just with a few drops vinegar.
Otherwise I use this white cleaning stone you maybe know it was initially invented by BASF.
