    Ok, I need some help with my yellowing problem. I got a bunch of old LEGO Bricks second hand, and a whole bunch were yellowed. So what I did, was take them and put them in a bin for around a month. When I finally got to fixing them, I used 3% hydrogen peroxide and set them out for around 3 - 4 hours. The whites did perfect. The transparents did not. They had a very orange tint to them, and still do at the writing of this. So if anyone can help me figure out this issue, it would be greatly appreciated. Thanks in advance! -legostarwars1425 P.S. Some of the parts are cloudy too. If you can help with that, that also would be greatly appreciated. Thanks again!
  2. Hello, I'm having concerns for my bricks yellowing over time. I'd like to prevent this as much as possible, without having to build in a windowless dark room all the time. I'm already using the curtains in my lego room as much as possible. However, with summer being back soon, UV light will increase and thus enable the bricks to yellow faster. I was thinking about purchasing some UV filter foil to apply to my windows. Does anybody have any experience using UV filters on windows? Will they actually work? And where can I get those? I've seen a few online, but they are very expensive (€35/m2). What is the best place to buy them?
  3. Hello, hope this is the correct forum to post this in. I was hoping someone out there could help me know if it "safe" to use the hydrogen peroxide method to "de-yellow" or restore bricks on colored bricks to their old color. I know that it works on whites and grays but has anyone tried this on other colors whether Modulex Colors or not? The bricks I am trying to restore are the Modulex red and Modulex Pink along with the Modulex Pastel-Green and Modulex Pastel-Blue. The really bad ones are the red and a few of the pink and Pastel-Blue while the Pastel-green is bearable but still needs work. I was hoping someone could help me on this. Thanks! -RailCo
  4. I was recently inspired to do a simple test on the effect of sunlight on brick yellowing. This May I had new windows installed in my house and this has resulted in more time with the curtains open enjoying the views and sunlight. I started to worry about the effect of sunlight on my MOCs and trays of bricks for builds in progress. The new windows have a coating that is supposed to improve energy efficiency, its called "SmartSun" glass. I also wondered if this would reduce the risk to the bricks. So what I did was place 4 sets of brand new white bricks in various sun exposure conditions. All were on the south side of the house for the last 6 weeks (summer in my area). The white bricks sandwiched by red bricks were taped to the outside of a window directly exposed, the blue were just inside the same window. The yellow set was behind a patio door with glass that is approximately 25 years old. And the black set was left in the dark the whole time. The results are essentially a lack of results, I saw no yellowing on any of the bricks, see pictures below. Now 6 weeks is not the same as years, and bricks mounted vertically are not the same as a build that is actually outside with the sun beating directly down on them. But for my purposes of concern about LEGO being exposed a few hours a day, indirectly through a window, this 6 weeks of continuous exposure is equivalent to at least several years worth. I'm still going to avoid excessive exposure to sunlight for my builds, but this definitely reduced my concern.
  5. So almost all of my misb sets are from the 1990 to 1995 period. I have heard about "oxygen sensitive white bricks" and yellowing of sets that are still misb, so I am worried that I won't be able to keep them immune indefinitely. So far none of them have shown any signs of yellowing, even in the oldest ones, do you think that if they were going to yellow, they would have by now? I keep most of them in a dehumidified basement that gets a little sunlight (not directly) and the others in a closest that also gets very little sunlight. Is it possible to keep them new indefinitely or will they eventually yellow regardless?
