HOW TO WHITEN OLD YELLOWED LEGO BRICKS

I thought I would run a little experiment to see if it would be possible to whiten my 35 year old lego bricks. This is a very simple technique that only requires a bit of washing followed by having the bricks sit in some hydrogen peroxide out in the sun. The results are amazing.

I seen the thumbnail and now I’m looking at my tan blocks thinking they could be very old white blocks

[@AllThings80s]

LOL

[@ElecV]

Looks like the result of staying white depends on the Set - Got the 8880 and 8480 - both very yellowed - used a long time for the bricks in the Peroxide to get them white - and after arround half a year the bricks turn yellow again. And the sets were build and didnt get any sunlight at all in a most times dark room. Only the white axles of that 8480 set didnt want to go yellow after all the years.

[@AllThings80s]

It seems that there's just no way of knowing which bricks will yellow and which ones don't.

[@guillermoc74]

For step 1, instead of washing one by one: put all the pieces into a bag for women's clothing and wash them in the washing machine under a delicate cloth cycle. I wash all my LEGO like that

[@AllThings80s]

Thanks, I'll try that next time.

[@deamaharani]

a bag for women’s clothing? can you pleasee make a video about it?

[@dilemmix]

@@deamaharani It's also called a delicated bag. For protecting your delicate items such as bras. Any supermarket has it or otherwise women's lingerie stores have it.

Hi, I did that process in a very large LEGO bricks not only whites affected by the sun during Years of been near a window in my parents house, and after a few weeks and other a few months the LEGO all became like Tan to yellow again. including minifigures and flags and wall panels etc. so I do not recommend do this process, it works great first time but the will get yellow again so if you repeat the process maybe will damage the bricks, I lost a few light gray plates as they were very old from a 80's space ship and they broke in the middle. so do it at your own risk

[@Commander_Commando]

Thanks for posting! I saw a down under the bricks video about this process not being good. Are your pieces still free of the yellow and also retain their integrity?

[@AllThings80s]

Yes, they are still white and have their integrity.

[@cesruhf2605]

ig it depends on the year cause doesn't lego change their abs plastic formula?

[@MK-er7cx]

damn i wish i had seen this earlier. i threw away some decent pieces because i thought it was due to sun exposure. could have totally cleaned them up

[@AllThings80s]

Oh no!!! Yes, you could have saved those bricks.

[@erikalexander414]

Worked excellent , days in the hydrogen peroxide amount to a "whitening shade per day" I did it 2 days and the light browning was visibly whiter but could have been whiter

[@AllThings80s]

I did mine for about five days and the results were excellent.

[@creative43bricks75]

Wow that's helpful to clean my old Lego now

[@AllThings80s]

[@jessedunda2130]

Another recommendation, instead of a tooth brush scrub them with a makeup brush, much less chance for abrasions especially on flat pieces and printed minifigures, much less abrasive.

[@ubervostok6222]

Hi, I have a inquiry. How's the bricks right now? Is there any coming back on them to the yellowed condition?

[@AllThings80s]

They are still brilliant white. I'm extremely happy with the result.

Yes they are but I keep them stored in the dark.

[@silviadecarli5463]

hi! i used this method with light gray pieces that were sun damaged in only a portion (half of the piece were covered by other lego pieces) but after 3 days of soaking in H2O2 the yellowing was gone but there were still some difference the part that was sun damaged is more light compared the the covered part any ideas?

[@AllThings80s]

I'm not really sure. Sorry.

[@GhettoWagon]

You left the part in the solution for too long I had it happen on grays. It may or may not fade back to a slightly darker color in time. I stopped using hydrogen peroxide in a container after this and use a paste like a hair lightening product. kzbin.info/www/bejne/b4rYp2ePfJiDf6M I used it on a gameboy too worked nice.

[@vince7207]

Carefully tape over the fresher area so the poorer area gets more exposure?

[@5trider29]

Serious Question....I doing the process right now (first time) for my light grey bricks, and I only bought 1litre of hydrogen peroxide. You said the process will take a few days? So I should leave them in the sun for few days til the color restores? I ask cos 500ml bottle costs me about USD5 (bought 2 bottles), and prefer not to buy more.

[@AllThings80s]

Yes, I put the pieces in the hydrogen peroxide and then sealed the lid and left it out in the sun for a few days. There's no need to add any more hydrogen peroxide.

[@greggriffin287]

This is for white bricks. For light gray bricks, use hydrogen peroxide but do not put them in the sun like you would with white bricks!

[@greggriffin287]

@Mike Nonya I read that light gray shouldn't go in the sun when using peroxide so I soak mine in peroxide indoors, but it sounds like it works either way. Cheers!

[@GerbenWijnja]

If the sun is shining, and it's not cloudy/overcast, then 3 or 4 hours should be enough. You can use the hydrogen peroxide multiple times! It will lose its strength after a couple of times, and you will notice that less bubbles are forming. Then it's time to replace it.

[@greggriffin287]

@@GerbenWijnja thank you. I wish I would have known this before I put mine in the sun. 3 hours in direct sun was too long for my light blueish gray bricks. They look okay, but were over-"bleached". I should have tested just a few pieces first before putting all 200 in there. Lesson learned, the hard way. Hopefully others will see these comments and check their light gray pieces after every 30-60 minutes and pull them when they are lightened just enough.

[@moditorplayz]

Will my light gray/LBG turn white when i bleach it?

[@derekwagner157]

2 to 5 hours soaking in direct sunlight would have done the job. The result would have been no paint damage at all. Also use a glass Pyrex pan to allow more sun and better exposure for the bricks which would be more spread out. Finally 3 percent solution is fine.

Are there any side effects, because I heard that soaking them in hydrogen peroxide in the sun works but can cause them to yellow faster

can I do that even if the bricks have a sticker and print?

I don't recommend it on printed bricks as it will change the color of the print and you certainly don't want to be putting stickers into any liquid.
