I tried doing a couple of the clear parts by hand and they came out pretty good.

I have recently buffed one of my friend's car's headlights using a headlight restoration kit (3M makes one but there are many others also).

It basically involves wet sanding with very fine grit sand paper and then polishing using a compound.

I have not tried it on Lego yet but am positive it could work, If I had to try something this would be my first try and best bet.

You will have to use progressively finer grades of wet sanding paper.  Use wet/dry sanding paper, that is made especially to get wet.  You'll ought to talk to some of the folks in the scale modeling community....

Brasso works well for removing small, fine scratches. I've used it to polish many transparent pieces in the past. It doesn't do much for larger scratches though.

That is why you use progressivly finer "grits" of wet/dry sandpaper.  You have to use it wet, and you use the more coarse paper to sand out the scratch.  Then you use progressivly finer paper to sand out the (buff out, really) the scratches made by the sand paper you just used.  At the end, you use some sort of polish...such as Brasso, certain waxes, etc.

While time consuming due to washing, it IS possible to restore bricks to like new condition.

You will need car polish and a buffer with a small disk

Wash your bricks, they can be wet, and build "walls"

apply car polish and buff. Make sure , like on a car, you move the buffer around and don't heat burn the plastic. once done and the bricks are in like new lustre , do the other side, and then the two remaining!

Finally you will need to wash them in hot water with a gentle brush to remove any left over polishing compound.

Is it worth it? sure it makes old bricks new again.

Takes A LOT OF TIME!!!

Sounds interesting.  What tool do you use to buff with? (Dremel or other)

Thanks,

More info about polishing bricks can be found in this topic. While this is undoubtedly of interest to Trains fans, we prefer that such topics be kept in the General Discussion and News forum for everyone to refer to more easily. :classic:

I do not see why posting a link to another forum would be a problem  ;)
About de-yellowing bricks there is a topic on EB too: http://www.eurobrick...?showtopic=7167
Vanish/Oxyclean + Peroxide seems indeed to be the good way for that.

I've already read that polish can be used to remove printings from parts, but I didn't test it for scratched bricks; thanks Konrad for the tip.

For transparent parts the system is different though: http://www.eurobrick...showtopic=76744
