Cleaning dusty LEGO

in Care & Feed of LEGO

If you are displaying your LEGO creations on open shelves, eventually they will collect dust. However if you do a quick dusting on them on a regular basis, you can keep those dust-bunnies at bay.

The challenge of keeping LEGO dust-free is the studs on top of LEGO elements. It makes it hard to just wipe them off with a cloth, as you cannot get between the studs easily.

There are some other methods though, that are very successful in keeping your LEGO-displays clean. Check out the suggestions below! ;)

:arrow: DUSTERS: natural feather dusters or synthetic dusters that are used to keep small display-items clean works quite well for LEGO cleaning. If you use this method, I would recommend dusting off you LEGO collection once a month. Here are some you might like listed on Amazon: Feather Dusters

:arrow: BRUSHES: soft, natural fiber paintbrushes that artists use are very handy to get into small crevices. I would recommend getting a large brush for general dusting of your LEGO-displays, and a smaller one to get into small spaces. Makeup brushes also work wonderful! Again; I would recommend a once-a-month cleaning with this method. You can find them at local stores as well as a good selection on Amazon: Paint Brushes, Makeup Brushes

:arrow: COMPRESSED-AIR DUSTERS: this is a product used to clean computer keyboards and other small electronics. It comes in a can, and provides a tremendous amount of air pressure to expel dust, yet it is safe for delicate items. Compressed-air cans are available at office supply stores. It is not cheap (about $5/can), but it does a really good job at cleaning away dust. My experience is that if you do a throughout cleaning of your LEGO collection with this method a couple of times a year, it will keep your displays in tip-top shape. Here are some examples: Compressed Air Dusters

:arrow: VACUUM CLEANERS: Some small, handheld vacuum cleaners have an option of switching over to blowing out air, instead of sucking it in. They also have various large and small attachments to control the airflow. This is a good option for very large LEGO displays, mosaics, or sculptures, however because the airflow cannot be controlled nearly as well as with compressed-air dusters, it may blow off some of the LEGO elements that are not well attached. So, I would not recommend it for small LEGO displays with delicate details. Here is an excellent example of this type of vacuum cleaner:
Metro Vacuum MDV-1BA DataVac Pro 4.5-AMP Computer Vac/Blower

:!: WARNING! Never use a vacuum cleaner in its normal, sucking setting to clean LEGO! Your LEGO bricks will end up in the belly of the monster!  :(

Thanks for posting this topic, I’m searching around for an easy way to keep my boys’ Lego sets clean/dust-free and these are great, simple ideas using household items! I also came across a youtube video on a lego-cleaning tool, Brick duster. Have you tried it before?
this is the link

Ann, thanks for sharing the video! No, I have never seen this before, but it seem to work great! The person has an eBay store where he sells these. Here is the link:

Thanks, very timely.

You are welcome, Gina! ;)

These are all great suggestions! I don’t want to lock my kids Lego away in some cabinet, and these are good ideas to keep them clean! the compressed air duster seems to work especially well! It is quite expensive, but you only have to use it a couple of times a year.

One thing you forgot. A toothe brush! Use a new never-used toothe brush and it dusts easity. Just dont brush the stickers too hard!

Tobymacboy, yes that works too! Although what I don’t like about toothbrushes is the angle of the handle. I found it is easier to use regular brushes. Also, I’m wondering if the bristles of a toothbrush would be too harsh for LEGO. I guess a soft brush would be fine, but I wouldn’t use one rated hard. It may leave scrathes on LEGO elements.

yeh i use a soft kids toothe brush i got from the dentist in one of those stupid bags

Paint brushes… That’s a great idea;)

Ashton, simple works best! ;)

I like to use a camera duster brush. It’s like a little hand pump bulb that has a brush on the end so you can brush and blow air at the same time. And they only cost about $4.

Aaron, that’s a grat idea I never heard being mentioned! Thanks for sharing! ;)

Another useful set of tips. tyfs!

My mom used to sort out Lego pieces sucked into the vacuum cleaner when she emptied it. That’s quite impressive.

LOL! Yeah, bless those moms who are willing to do that! :D
