Washing Dials, Hands and Crystals with dish soap

This is something I’ve done for several years now and have posted about it a few times. But I figured it was time to make a thread including all these techniques in one place.

Dials
I tried washing a junk dial one day just to see how it went. It worked well so it's now my default cleaning method. I use a good quality artist paint brush and mild dishwashing liquid. First close the sink stopper in case a dial marker comes loose (never had that happen but no need to risk it). Get the dial wet, soap it up good, rinse and blow dry with an air puffer. Sometimes you can get a water spot or two if you don't dry it fast enough, just wash the spot away, rinse and blow dry again.

This technique should not be used on matte dials or if you have water based lume. But on most of our rep gloss dials with lacquer based lume it will leave them flawlessly pristine. I've done this on dozens of dials, including a gen dial.

I always recommend trying any new technique first on junk parts to see how it goes and to get practice. Make your mistakes where they don't matter.

A couple other examples

Hands
Some hands washing examples. I use the same technique to clean hands after mounting them on thin plastic stick tools or a broaching file for the second hand. You can also hold them with plastic tweezers. Leaves them looking the best they can.

Pretty nice hands for rep.

Crystals
For me, cleaning a crystal is maybe the most PITA task in modding or watchmaking. Not the most challenging by far of course, just simply a major bitch most of the time. I also use the dish soap and paint brush technique to clean crystals. It can be done with or without the gasket installed to the crystal or even if the crystal is already installed onto the case. The drying process becomes more time consuming and painstaking as other parts are included, so especially when a case is involved I settle for ~95% perfect and finish with a lens wipe.

When you just can’t get that last little speck of dust or two off the inside, reverse roll some bracelet tape and hold it with tweezers. Barely touch it to the speck and lift it away.

Zeiss lens wipes are the bomb.

It’s not uncommon for any of these parts especially the crystal, to become re-contaminated during an install. For example if you have to take the bezel back off and the retaining ring and crystal come with it so you have to separate the crystal again with a die. I just go right back to the sink and start over, it’s a 3 or 4 minute job. Dial and hands are a couple minutes each. This is really a fast clean once you get the hang of it. Remember to practice first on junk parts. Happy modding!

I posted on RepTime about your dial cleaning technique after I tried it and was successful. I was surprised by a number of comments saying that tap water was a bad idea. I couldn't make heads or tails of their logic -- the essence of their comments was the the 5ppm chlorine in tap water and/or the mineral in hard tap water (I don't have hard water, but whatever) would damage the dial. I don't think that's even remotely possible given the short dwell times of the water on the parts and the fact that the water is blown off during puff drying.

Regardless, just wanted to thank you for sharing your methods. I've found them to be extremely helpful.

Did you expect something different from reddit?

Thanks for sharing. How would one go about cleaning a matte dial?

Just use matte water.

Seriously though, with matte dials, I just rodico it really well and blast it with multiple coats of matte krylon spray. Will hide a great amount of imperfections easily.

When I first started doing this I actually used distilled water but one day I ran out and just went with the faucet water. No change in results so I never looked back.

I've never seen the slightest bit of damage caused by rinsing for less than a minute and blow drying immediately. But if anyone does have hard or bad water, using distilled water is a cheap and easy solution. You can even add some pressure to it with a wide mouth (1mm or so) craft syringe.

I've never tried it so I can't say how water would affect the surface. But the lume could be a problem if it's water based. It would dissolve and run.

I might have a junk matte dial I can test, but in the meantime I would stick to the usual methods of dry cleaning - light touch of Rodico or not too sticky tape, dry lens cloth, dry artist's brush, dial cleaning pen, air puffer etc.

In most Western and Central European countries, the water is relatively hard, leaving whitish marks on any surface it touches if not wiped off. We often need to clean water taps with a vinegar solution. That said, I agree - the dial doesn’t stay in contact with anything long enough to leave such marks.

@KJ2020 Great tutorial. It seems we often get lost in the weeds of more complex watch repair tasks and it just doesn’t seem right that a simple process can make such a difference.

I haven’t tried Zeiss wipes but will. I’ve been using Zeiss lens cleaner on my watch hands, crystals, and dials with outstanding results. At my local supermarket (Southern Cal.) a Zeiss lens cleaning kit, including a pump spray bottle of cleaner and a a super-effective lens cloth cost only $4.99!

My favorite dishwashing liquid is Dawn. I also use it to soak watch parts that have been over-lubricated before my regular parts cleaning protocol.

@dogwood Those with water concerns may have a point. Here in California, some cities have terrible water. If water is an issue, a bottle of distilled water costs less than $1.50.

Yes, I’m very lucky that in Vancouver the tap water is incredibly soft. The water source for the city is several large rain / snow melt fed reservoirs that are less than 30km from the city. A good proxy for how hard water becomes is the distance between where it falls as rain and where it comes out of your tap. Large distance = more time to accumulate minerals. My buddy’s condo building in Vancouver just installed a system to add minerals to the municipal water to stop the super soft city water from eroding their copper pipes and causing pin-hole leaks. I guess, Vancouver is the exception that proves the rule.

Why do people from Canada think it OK to brag about their water? 🤣 Actually, where I live, we have pretty good water except for drought years. We’re in the foothills of the mountains, on top of a massive bowl of alluvial sand and gravel. During good years, water from our Artesian wells is bottle quality.

Awesome tutorial @KJ2020 ! Thanks for sharing. I've got some gen GMT hands I wanted to clean for so long and I guess I'll try this method (will try one some rep ones first)
