Before following this guide, please bear this in mind :
Lastly, remember, retr0brighting changes the chemical composition of the plastic, making it weaker than it was before. Do not retr0bright if the plastic is already brittle and do not retr0bright if you are looking to preserve something and make it maintain the colors. Retr0brighting brittle plastic may cause it to break or break more readily. The Danish National Museum did a study on retr0bright and does not recommend it for the purposes of preservation due to the weakened state of the plastic and the damage it causes to the plastic.
Here's a super small, simple guide on how to
retr0brite keycaps. The same method can be applied to full keyboards, etc. E.G I used this method to retrobrite a case from an NCR G81-3007HAD and it worked brilliantly.
What you will need :
- Something to retrobrite
- Peroxide paste - I'm using 40vol (12%). You can pick this up at a hairdressers/drug store. The official retr0brite guide suggests something slightly different, but I find this bleaching paste works completely fine.
- Oxy stain remover - this acts as a catalyst. Very important.
- Gloves! Peroxide isn't nice!
- A small bowl and spoon
- A source of UV light. Leaving it out in the sun works, but I'm using a UV lamp
Step 1.
Make sure your keycaps are nice and clean. I use denture tablets in hot water to clean them.
Step 2.
WEAR GLOVES DURING THIS STEP. BURNS FROM HYDROGEN PEROXIDE AREN'T NICE, TRUST ME.Mix the peroxide paste with the oxy cleaner. The oxy cleaner won't mix very well with the peroxide paste, so you'll want to dissolve it in boiling water first. The amount of oxy cleaner you use doesn't matter too much. Roughly you want to use 1/4 teaspoon for every 200ml-500ml of peroxide paste that you use.
After dissolving the oxy cleaner in boiling water, just add the peroxide paste and give it a good stir. It will look something like this :
Step 3.
Apply the mixture to your keycaps/keyboard. You want to make sure that the coating is fairly thick, but not so thick that it becomes opaque. Remember that UV light is an essential part of this process.
Step 4.
Leave the keycaps/keyboard under a UV source for a few hours. I personally left it overnight for about 12 hours.
Step 5.
Rinse the peroxide paste off and enjoy the results!
Retr0briting is really easy, and I hope this guide helped some of you out.
