Life has been complicated and things culminated with a family crisis and the loss of my grandmother in September, but life continues and doing things that you enjoy helps in these situations, so finally back with a very simple post about retro computing.

What is Retrobright? It’s the technique used in retro computing to take plastics that the time and exposure to the light has yellowed and return them to their original color using H2O2. Internet has a lot of information regarding this since it use started in 2007 but the best way of learning is aside of reading about it, just doing a couple of experiments.

Over the past weekend I did a first quick attempt using peroxide that you normally would use to deal with your hair if you are going to use dye. Tested with cream and liquid to have a first experience with the pros and cons of each. I selected a few bay covers to test this out, if I ruin the pieces is not the end of the world.

The cream is much faster but you have to be much more careful since marbling is a real danger, of course you can prefer a homemade cream and make it less strong, but still the danger remains. I repetead the process a second day since the weather was kind enough of stoping the strong winds for a few hours.

The process is not entirely complete, since I didn’t considered that I need a lot more liquid than cream, but was a good experience and will finish it next weekend once I buy some more peroxide. The difference of that piece that was pretty much brown by now is very noticeable!

Additionally, tested the metal polisher pictured above along the peroxide to recover the chrome look of metals, presents in a lot of old computers and you can really tell the difference! This metal covers are from my NEC V20.


Well, I hope to start posting more regularly again now, see you all soon!
