What is the best way of getting muck out of bricks?

Question

I purchased a large bulk load of bricks for my 7 year old. Most have washed up quite well, but some of the bricks have various substances stuck in their underside.

The types of foreign substances vary, eg. mud, playdough etc.

What are good ways of getting the muck out of the bottom of bricks?

Answer 1

best way i found so far is simply using a plastic-toothpick (wooden ones should also do the job). just get the muck out as good as possible and then wash the bricks again the remove the rest.

if the muck is too hard for a toothpick, use a metal needle or a very thin screwdriver - but only do this if you can't avoid because you might be scratching/damaging the blocks (wich shouldn't be so problematic to the inner- and underside, but anyway you should avoid it).

Answer 2

For larger quantities of really tough muck that's stuck in the tubes on the bottom of bricks, I've had some success with scewing in a cross-headed scew and then pulling it out.

Answer 3

Soaking in water for a long period of time (a few hours is usually enough) and then using a pipe cleaner to sweep out the residual muck has proven to be very effective. The pipe cleaner is gentler than some of the other things that I've previously used (toothpicks, small screwdrivers, etc.). A Q-tip with a very small hide should also work well.

Answer 4

You could also get yourself a can of compressed air - it works on very small areas on my motorbikes so I'm sure it'll do an equally good job on some lego bricks. Here's some on Amazon...

Answer 5

I suggest to let them soak in water for a long period of time (2 days) before trying to clean them. The water will not affect the Lego plastic but some other elements (especial dirt and food) will soak it up. This makes it a lot easier to simply rinse out or scrub off the dirt.

The plastic toothpick (like @oezi suggested) is great for very small corners. For the tougher crud, I suggest wood tools (like sculpting tools) since they won't scratch the soft plastic but are hard enough that they don't just bend.
