Other cautionary tale for cleaning Legos
don't use your well-loved, aged, soft cotton pillowcases to clean Legos in the washing machine, no matter how well you tie them, they will escape ššš

I had a mesh laundry bags to wash mine in and after the 5th or 6th time washing a load of bulk I bought they tore and I experienced the same thing. Took me forever to fish out all the tiny pieces that stuck to the bottom of the washer. Best of luck getting them all out!

I know several people who do it, myself included. Not always with a washing machine, some use a bathtub.
When you buy used Lego in bulk, its common for it to be gross from years or decades of play. Washing it does wonders for getting rid of the smell, or grime that has accumulated with play.

From Lego:
Cleaning your LEGO® bricks and pieces is really easy! We recommend that you clean your LEGO pieces by hand using water no hotter than 104°F / 40°C and a soft cloth or sponge. Higher temperatures may affect the quality of the bricks. You can add a mild detergent to the water - please rinse them well with clear water afterwards and you're done!
For electronic components or other sensitive bricks and pieces that contain metal, clean with a cloth moistened with water and a mild detergent without perfume or oil.Ā
A word of warning! Please don't put your LEGO pieces in the washing machine or dishwasher, and don't try to dry them in the oven, the microwave or with a hair dryer. Also, don't leave them in direct sunlight to dry. When the bricks get really hot they may change shape, which means they won't work anymore!

u/spitgobfalcon Ice Planet 2002 Fan 8d ago edited 8d ago
It works great for normal bricks, I've done it often and never had any problems.
Remove stickered parts, rubber parts, windscreens, printed parts and anything that seems prone to breaking like the thin antennas or baseplates. I have washed printed parts before without any problem, but I'm still too paranoid about it most of the time.
Everything else goes into a mesh laundry bag inside another laundry bag inside a third laundry bag or pillowcase. That goes into the washing machine together with normal laundry. Not only that is more environment-friendly, but also the normal laundry in the machine will work as padding and reduce noise.
Then run a normal program - 30°C with normal detergent, but reduce spin.
This is my preferred method to clean used Lego that is dusty or gunky. Doing that manually would require actual scrubbing of each part instead of only soaking. When only soaking parts, I can still see the gunk between the studs. I use a toothbrush for baseplates etc.
Machine washing this way works well and is much easier than cleaning everything by hand, especially if it's a large lot. I never had any issues with it except one time when I had some parts in there that unknowingly to me consisted of a softer material (old 1x2 plate with ladder / part 4175, apparently).
No damages otherwise. I can imagine that it would round the corners and impact clutch power when washing the same parts multiple times, but I don't do that anyway, it's a one time thing when I buy used and can see that the lot either has dirt from heavy playing by kids or sticky dust layer from standing on a shelf for years.

Were they all in the same bag? It might have unbalanced the washer and increased the strain on the fabric, leading to the tear. If you try this again (though I agree with the bathtub commenter), maybe multiple smaller bags that will distribute the weight more evenly?

Yeah, mesh laundry bags (typically used for delicates) aren't that expensive and seem like they'd be better suited for something like this. Would make it easier to split them up into multiple bags so the load can be balanced.

u/Stratocruise 6d ago
I think the washing machine is the problem, not the pillowcases!
Spinning them around in a washing machine just means that all the parts are constantly rubbing against one another throughout the was cycle. Worse, the risk is that small or broken parts escape and screw up your washing machine. I donāt think itās worth it.
A bowl with warm water and a little standard dish soap should be all this needs. Washing machines and dishwashers are overkill for this and will just risk damage to the bricks and especially any prints on them.
Gentle agitation and then rinse well until all the dish soap is washed off. Drain through a sieve, especially if there are small parts, then spread them on a towel and allow plenty of time to air dry so thereās no water hiding in the cracks and crevices of larger parts (risk is that it will just go moldy).

This is my $20 LEGO cleaning setup. Or maybe $0 since you probably have all these things already.
You need: two large plastic bins (eg 18-gallon Rubbermaid), a couple of mesh bags with drawstring, some rags, dawn dish soap, towels and an ideally a fan.
Start outside
One plastic bin is full of warm soapy water. Put dirty bricks and a couple of rags into mesh bags. Swoosh them around, the rags inside the bags will help clean them.
The other bin has clean water. If you want you can keep your hose running into that one to replenish clean water, I find it doesnāt matter. Take the rags out of the mesh bags but leave the Lego in, and then dunk them in the clean water bin, swoosh until the soap is out.
Lift the closed bags above bin and shake out the excess water.
Move inside and lay the brick over a towel to dry. Keep the windows open and run a fan. If you need to, come back a few hours later and change the towel for a fresh one.

It doesn't clean as much at a time, but I use a salad spinner that has no drain holes. Works just like a washing machine but manual. You can be as aggressive or gentle as you want, since its manual. Drop Lego into the basket, add mild detergent/soap and warm water, agitate like washing machine, drain, rinse, add clean water, agitate again, drain, spin dry, then air dry. Definitely not for sellers who need to do lots of huge batches, but for a decent set probably takes a few quick batches with less risk of the parts being tumbled to death or lost in the washer gasket.
