Rail Co Posted August 18, 2017 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 Share this post Link to post Share on other sites
TechnicRCRacer Posted August 19, 2017 (edited) Why don't you find a very cheap Modulex brick in bad condition on BL as an experiment with the hydrogen peroxide? I found this video for normal bricks: Haven't tried it myself... Edited August 19, 2017 by TechnicRCRacer Share this post Link to post Share on other sites
