Need advice on Retrobrite
« on: Thu, 20 February 2014, 15:51:31 »
Hello.

I have two moogle kits from BTC-53's (didn't got the second one yet tho) that i'm using/swapping on a Capacitive plate mounted & pcb domes Chicony-kb5161, just because the profiles are better for me and they feel better on corners.

So, they're SO yellow. I was thinking about painting them, because I want them blank white, but wouldn't mind trying to clean. I always read about dental tablet* and such.
They're pad printed. So, if the dental floss or any other metod could remove the printing, it would be a total bonus.

So, here's my questions:

  • How exactly the dental floss method works? (Amount of liquid, amount of dental tablets, tablet brand or type, time submerged, brushing, etc)
    Will it remove pad printing? If not, how could I remove it?. I'm not sanding any key, that's just dumb. Also wouldn't want to use a uncontrollable solvent or such.

I would also like to make the case cleaner, it's a full size 2 piece screwed case. How can I do it?

First, the dental floss mod is where you put a 1 cm length of dental floss in the spring of a buckling spring keyboard to quieten it.

Retr0-brite is a process of mixing harsh chemicals (especially bad for the eyes) and exposing the plastic to sunlight.

Apparently, a couple of decades ago, it was popular to mix bromine into ABS plastic for fire-retardance, and it caused the plastic to yellow over time.

I have tried it several times with a couple of resounding successes, several partial failures, and many total failures.

The trick is probably getting the chemical mixture into a nice gel that does not dry too fast, and exposing it to good strong sunlight for several hours.

As far as removing pad printing, you will probably have to abrade it. If I were doing it, I would use my electric eraser, but I am an old man and only an old-school architect, draftsman, or artist is likely to own one, so try a buffing pad on your Dremel instead.

Were our leaders just stupid? Well, maybe. But there’s a deeper explanation of the profoundly self-destructive behavior of Trump and his allies: They were all members of America’s cult of selfishness. You see, the modern US right is committed to the proposition that greed is good, that we’re all better off when individuals engage in the untrammeled pursuit of self-interest. In their vision, unrestricted profit maximization by businesses and unregulated consumer choice is the recipe for a good society.
Support for this proposition is, if anything, more emotional than intellectual. I’ve long been struck by the intensity of right-wing anger against relatively trivial regulations, like bans on phosphates in detergent and efficiency standards for light bulbs. It’s the principle of the thing: Many on the right are enraged at any suggestion that their actions should take other people’s welfare into account. This rage is sometimes portrayed as love of freedom. But people who insist on the right to pollute are notably unbothered by, say, federal agents tear-gassing peaceful protesters. What they call “freedom” is actually absence of responsibility.
Rational policy in a pandemic, however, is all about taking responsibility. The main reason you shouldn’t go to a bar and should wear a mask isn’t self-protection, although that’s part of it; the point is that congregating in noisy, crowded spaces or exhaling droplets into shared air puts others at risk. And that’s the kind of thing America’s right just hates, hates to hear. Anger at any suggestion of social responsibility also helps explain the looming fiscal catastrophe.  – Paul Krugman 2020-07-28 NYT

Sorry, I meant dental tablet!

tablets take off the grime but won't take away yellowing from old age
