LEGO cleaning techniques and tools

I usually purchase LEGO parts at yard sales and the like and would like to disinfect them before using them. Can I use any spray disinfectant on parts without ruining them? Should I be wary of any disinfectants that would cause LEGO parts to fade in color?

    Hi Ivan, if you take a look at my answer to the linked question, you'll see that The LEGO Group recommend using a Mild Bleach for disinfecting your bricks. Jul 14, 2012 at 10:26
  • Soaking the parts in a 50/50 mix of warm water and white vinegar works as well - it cleans, removes odors and disinfects without leaving any residue.

In the past I have used dish soap and a basin and just soaked them in hot soapy water for a while. I then learned that MegaBlocks float while LEGO sink.
