Cleaning keycaps with... denture cleaning tabs!
« on: Wed, 19 August 2009, 07:18:47 »

"Let me see that keyboard, dear."

This came to my mind when I was reading a random unrelated German article that mentioned how some kid got sick by chewing on nasty lego bricks.. anyway the end of the article had some tips for parents on how to clean Lego bricks, so their kids don't die from infections (and rather choke on them instead, I guess). One of the tricks was to put them in a huge bowl with some dental cleaning tablets.

I figured that Lego bricks and keycaps are close enough.. so I gave it a try today with some boards.



I used the "Kukident Active Plus" brand - which should be easily available in Europe. They came in at 2,40 Euros for 33 Tabs. Pretty good deal. If you already lost all your teeth and are using dentures anyway then you are probably already set.

Here is what I did:


1) Get some big bowl, put in at least 4 or 5 tabs, depending on how many keycaps you plan to clean.


2) Add the keycaps, make sure they are evenly distributed around the tabs.
Now here is the cool part - I also added in all stabilizers as well, because the tablet box claims: "Our corrosion preventive special formula protects your dentures metal parts from rust and corrosion." - What more could we ask for?

Note: I had to add another tab here since the keycaps turned out to be more than expected (damn terminal boards!)


3) Add hot water. A lot of bubbles will start rising and the water will probably change colour.


4) Let it rest for a while and let those tabs do their magic. After about 20 minutes the foam started to disappear and the keycaps should be good to remove.

5) Time to get the keycaps dry again. This is up to you. I usually use a pasta sieve and give them a last clean with cold water. After that I use a hair-dryer to dry them.
 
So far I am very happy with the results and it even cleaned some keycaps which seemed really filthy with worn in grime.

That's some great idea there. :thumb:

An academic research paper on this would certainly be entitled "A novel method for cleaning keyboard keycaps". :D

It seems like these denture cleaning tabs are quite useful for cleaning all kinds of things, as a quick search showed. And apparently it's not exactly a new discovery either. Interesting chemistry cocktail... some acids here, some peroxide there, and a major ingredient sems to be sodium bicarbonate. That should make for some nice chemical reactions.

They are gently abrasive (due to the effervescence, not the tab itself, per se), but nothing that would damage a key.  It's probably a lot less damaging than putting them in the dishwasher.

Yeah, cleaning them by hand would require rubbing, and we all know that can really hurt the natural texture of a keycap (especially if you're rubbing your Wang)

Can't wait to try this out, probably the best method I've seen so far ^^ (dishwashers scare me)

I always use the dishwasher for cleaning my keycaps.

Works extreemly well.

I place the keycaps in a cleaning bag to prevent them from wondering around.



They come out squeaky clean and never damaged any.

That turned out pretty well I'd say. Any remaining traces of dirt? How long did it take per board?

There were no traces of dirt left after I took them out of the denture cleaning liquid and gave them another cold shower in a pasta sieve. However, one key had something written on it with a finemarker - "123" on a "7" key for some reason. This remained in place. I could easily rub it off with alcohol though.. odd.

If you want to speed things up you can probably finish an entire board in an hour. I usually let them soak for at least an hour though.

Nope, no scrubbing or rubbing of the caps. Just make sure to put the tabs into the bowl before adding the keycaps and then let them in there for a while. If you still find them dirty (very unlikely - has not happened yet), just repeat the same thing again. Usually 4-5 tabs seem to be enough for a full set of keys.

Here is my cleaning method and it has always given me the best (and not much work) result: 1) Take the caps down and soak in warm water overnight; 2) Use ultrasonic cleaner, use a few drops of dishwasher liquid and a cap of ammonia; clean for 2-4 minutes.

Air dry and bingo!

One comment on dishwasher method: careful with temperature. My dishwasher's default setting has pretty high water temperature and it might not be good for some caps.

sorry to bump this, but I just used this method on my hhkb keys. The white ones were starting to show gunk a little more than the black keys were. I left them in for about two hours, used a pasta sieve to strain the water, ran some cold tap water over them, and then let them sit out in the shade outdoors (no wind, hot vegas air). 10 minutes later they were ready for assembly :) Perfect technique, sixty

I haven't tried the denture cleaner, but Simple Green worked well for the moderately dirty keys on my SGI board.  

A number of people have mentioned using it, but I haven't seen details, so:
I put the keys in a bowl, dumped 1 part Simple Green, 8 parts hot tap water, and stirred it a little just to mix in the cleaner.
After letting it soak for 10 minutes, I poured out the fluid, rinsed the keys, and spread them out to dry.

The instructions on the bottle say you can dilute at 1:10, but the 1:8 ratio was convenient, since our kitchen stuff is mostly not in sane (metric) sizes: I used a one-quart glass bowl, 16 fl. oz. water (half a quart), and 2 fl. oz. cleaner.
The 10 minute period was chosen more or less arbitrarily.

It worked nicely, all the scunge was gone without any scrubbing.
Next up, a bigger challenge: my roommate's old (and never-cleaned) Northgate.

this looks like an easy way to do them in bulk.

This does look a lot easier than the method I would use of soaking everything in a bucket of Simple Green.  With that method, you would still have to do some scrubbing to clean the parts.  I appears with this that you just soak it for awhile, and the effervescence and abrasives in the tablets do the heavy lifting.

I may try cleaning the doubleshots I bought from Kishy with a combined solution of:

1 part Simple Green
1 Denture Tablet
1 TB Oxyclean


I sent your doubleshot keys today too, you should get them within ~10 days I suppose, however they are already clean anyway.

PS: This method is also already very popular in the translated Korean version and got featured on their front page recently.

Glad everyone likes the method.

so I finally got my Dell AT101W today, already took it apart. The keycaps I'll just clean using the denture tablets. But what about the board?



Can I just put this under the kitchen faucet and clean it with a brush? My concern is mainly the electronics, will they survive the water?

Please advice what I should do.

I'm not planning on actually taking apart the individual switches.

I would dust it with a feather duster, use a Lysol wipe or spray some Windex on a paper towel and wipe it off.  I wouldn't put the body under water by any means.  You could wash the case under water or in the dishwasher, though.

I usually use a combination of air compressor + toothbrush on actual boards/switches. Be careful to not rub the switches too hard though, especially ALPS like to fall of easy because they only have 2 solder points.

Regarding the guide: I had the first failure with the method the other day, I guess these keycaps are beyond hope. Gave them 3 cleanings and one with another cleaner. They are still damn dirty.

Did you use the toothbrush at all on the keycaps you soaked in the denture cleaner?  When I had braces as a kid, I used denture cleaner on my retainer after the braces came out.  I was instructed to still brush my retainer as the denture cleaner would not necessarily be able to take out the "big chunks."  Just a thought.

Ok, thanks.

The switches are mounted on this metal plate. And looks like there's not an easy way to detach the circuit board, so that I can have the switches+mounting plate by themselves.

If this was possible, then I assume it's okay to put the switches+mounting plate under the faucet, no? Since there are no electronic parts here.

Other than desoldering the switches, you can't take them off the PCB.  Even then, you wouldn't want to put them in water, because there is metal inside the switch, and you probably wouldn't be able to let them dry out properly.  If that were the case, the switch could malfunction and/or some of the internals would rust.

Regarding the guide: I had the first failure with the method the other day, I guess these keycaps are beyond hope. Gave them 3 cleanings and one with another cleaner. They are still damn dirty.

What kind of board / plastic? With some of the softer "standard" materials (ABS/PS?) the dirt seems to "dig into" the surface at times and can be almost impossible to remove completely.

At least if the dirt doesn't come off with fairly intensive cleaning, chances are it won't in actual use.
Hardware in signatures clutters Google search results. There should be a field in the profile for that (again).

This message was probably typed on a vintage G80-3000 with blues. Double-shots, baby. :D

It was a newer lasered Cherry G81-8300 or something, the caps look as if the board has been stored in a pond of mud, face down. They are the new thinner type of Cherry keycaps and should be PBT. I believe these are actually made in China.

I used the "Kukident Active Plus" brand - which should be easily available in Europe. They came in at 2,40 Euros for 33 Tabs.

Found those on Amazon.de, but they don't seem to ship anywhere outside Germany...
Any idea where else to find those ?

Kukident is just a German brand of Reckitt Benckiser. Whatever is common in France will most likely work just as well.

Sure, but being a bit lazy, I prefer to know working products rather that having to test them :wink:

i always use the dishwasher for cleaning my keycaps.

Works extreemly well.

I place the keycaps in a cleaning bag to prevent them from wondering around.

This seemed like about the right place to mention this linky about de-yellowing old cases.  Shown is a Commodore Vic 20 (basically just a keyboard without much computer in it anyways), though it could be applied to any yellowed old plastic tech.
 
I've used this formula myself just for the hell of it (cleaned up some "vintage" Nintendo consoles prior to selling on eBay) and it worked perfectly.  No damage to the plastics and they ended up looking much better than the photos in the link.
 
Perhaps a good compliment or alternative to the denture stuff.
