Advice needed for keycap renovation
« on: Thu, 30 January 2014, 10:26:24 »
After a very bad idea, all old yellowed keycaps of a vintage keyboard in a bath with bleach, the best and successfull solution I've found to remove white ugly (how do you say "tâches" in english ?) stain was to use very thin water-sand paper. Now they look much better but they would need either polishing paste or a glossy or mate clear.

Is there any good clear on the market (spray) that don't dammage plastics and are still very strong so they won't go away with time and typing ?

retrObright worked very well on the yellowed shell but almost not on keycaps, any advice also for a good retr0bright method or cocktail for these keycaps ?

A quick search has yielded the following suggestions:

- Peroxide hair bleach
- Whitening toothpaste and Mr Cleaner magic eraser

Thx but I've already seen these pages and there is nothing more than what you may find on the retrObright website.

retrObrighting keycaps is much harder due to the shape of these parts, max peroxyde concentration is 40 vol (100 vol is now forbidden, in France at least), and these bottles sold for hair bleach contain a not translucid creamy liquid, this is bad for UV penetration, mainly if you want to put all your keycaps in a peroxyde bath...

Anyway, I was not asking for that but for clear spray products for plastics that are strong enough not to fade away after months of keyboard use.

Some clears are very strong but they only can be used on specific paints or metals, they will damage plastics.

If someone already used such clear with success, let me know, otherwise I'll pursue googleing^^

Do not clear coat your keycaps.   :(
60% keyboards, 100% of the time.

Do not clear coat your keycaps.

Any surface film will wear off or peel off over the long term.

Many users like surface texture and dislike shiny keys, but it must be consistent to look good.
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
