When I purchase bulk LEGO bricks, one of the first things I do is to tip the whole lot into a mesh bag and give them a good soak in the bath (of course, I remove all the electrical bits etc. first). This usually gets rid of most of the accululated muck etc.

However, I am concerned that the very smallest pieces will slip through the net and end up getting lost en route to the bath or even disappear down the plugh hole.

The solution is obvious: to make sure that I use a bag with small enough holes that the smallest pieces can't fit through.

What, therefore, is the smallest component that LEGO have made?

You may want to use a cloth bag, to be sure. – Joubarc Nov 29 '11 at 4:49

The screwdriver is also very small, but I'm not sure it beats the lever handle. Also, one could argue it has to be detached from the tools wheel first. But if you buy second-hand lots, there's a good chance it would be detached, and it would easily escape through small holes.

Similarly, the various plumes aren't very large either:

I've physically compared a screwdriver to a lever. For the purposes of fitting through holes, the screwdriver is indeed slightly narrower than the base of the lever handle. – Kramii Nov 29 '11 at 16:30
That's what I call dedication. – Joubarc Nov 29 '11 at 16:42

One of the smallest pieces is the detachable handle on the 1 stud gear shift element.

It is the size of a thin pencil lead. – General Decline Nov 28 '11 at 16:45
A picture would be immensely helpful here. How thin is a thin pencil lead anyway? – BoltClock Nov 28 '11 at 16:48
A thin pencil lead (in the US at least) is 0.5-0.7mm. The handle is much thicker than that. – user23 Nov 29 '11 at 14:13

I had guessed that smallest piece I have owned is one of these (image courtesy peeron):

Minifig Accessory Helmet Floodlight

It really is stupidly small (so small that I've lost the only example that I possessed).

However, I have since discovered that the lever weighs less, and that the screwdriver will fit through smaller holes.

Update: I've recently come across some of these:

Insect antenna

It's an antenna from the Twitch minifig in set 7599: Garbage Truck Getaway. They're pretty small.

I had no idea that even existed. – Joubarc Nov 29 '11 at 17:19
It comes with the Starwars Clone Troopers, along with a "rangefinder" type piece as well. It's a "headlamp" that attaches to a clones helmet. Rangefinder can be seen here: has a wider end than the screwdriver – Zhaph - Ben Duguid Nov 29 '11 at 19:55
I have one of these and wondered what it was. With four kids in the house, I suspect I won't have it for too much longer... :/ – retracile Dec 1 '11 at 2:16
@Zhaph-BenDuguid LEGO aren't distributing those pieces with the newer ARC trooper gear – shea Feb 22 '13 at 2:50
@bungeshea Yeah, it looks like they're just using the "targeting scope" and visor options - for example in 9488 – Zhaph - Ben Duguid Feb 22 '13 at 9:58

Minifigure hands are very small:

I've always thought those flat, round 1x1 pieces were the smallest sphere-esque shape. Most of the other pieces here are longer in at least one dimension than these guys.
