This is how I wash LEGO parts… how do you do it?
I’ve tried a few approaches. The laundry washing machine (in a mesh bag) worked fairly well, but I think a few bits got loose and got in the drain so I stopped doing that. The dishwasher (mesh bag in the top rack) also works OK, but I think it gets too hot in there – I had some warped bricks from the heat. Handwashing seems the safest, to ensure I don’t lose any parts down the drain or have them melted. If the water is cool enough to not damage my hands, it’s cool enough to not damage the bricks.
I always wash used bricks when I get them, and also any model that has been on display for any length of time tends to gather dust. I’m very allergic to dust, and I live with someone who’s very allergic to animal dander, so I need to keep my collection clean.
Anyway, here’s the four step process I use to wash bricks. Please post in the comments if you’ve found a better way or have any war stories about dirty bricks….
1. Soak in soapy water. I use All Free/Clear laundry soap – I figure if it’s good for synthetic fabrics it should be good for plastic bricks.
2. Transfer to mesh bag and rinse in bathtub. I had to do this in three batches, I had so many dirty bricks.
3. Use laundry basket, lined with towel, to carry to living room.
4. Dump out on towels on living room floor, with fan blowing on them. Luckily I live in coastal California, so the humidity is low and they actually get dry this way. I’ll stir them periodically, but they’ll be dry enough to sort and put away in a day or two.
Anyone want to come over and help me sort? I’ll give you free pizza!
