Had a pair just like them, except from the brand, many years ago. Quite fun to revisit an old memory and a really good job making them look like new with a twist 🙂
Is that WD-40/lubricant spray used to clean the electronics with? Isopropyl alcohol is better to use for cleaning electronics as it is safe to use on circuit boards since it evaporates and doesn't leave residue. If you don't have a UV lamp for retrobrighting yellowed plastics, you can put outside in the sun with peroxide, it just takes a lot longer than using a UV lamp. However I do appreciate you keeping these out of the trash and giving them a new life. If you want to learn more about retrobrighting, Odd Tinkering has an informative video about it on RU-vid. I think it's on his Odd Experiments channel.
This was... pretty poor honestly. You should not have painted them only to have a section exposed to save the text. You should have used hydrogen peroxide with a UV lamp to remove the yellowing effect. And the masked off section just looks bad.
Not bad! You might try the retrobrite method next time. If you have it available, Hydrogen peroxide and UV light will bring the yellowed plastic back to its original color.
Ну это очень грубо.Сначала шкуркой,потом покрасил.Это не красиво.Перекись водорода 12%,лучше в процентах больше,скажем 40%.Берём желатин пищевой и смешиваем с перекисью,получится желе.Намазываем этой смесью изделие из пластика и обматываем пищевой плёнкой,для надёжности кладём ещё и в пакет.Оставляем на пару дней на солнце(если солнце светит постоянно,хватит и одного дня).Впрочем,чем больше % водорода,тем меньше нужно времени на солнце.Таким способом возвращается оригинальный цвет пластика и он как новый.
