are really yellow? I just bought the Tower Bridge and a lot of the white and
light grey bricks are are really bad. I’ve heard the best way is to use 3% hydrogen
peroxide and let it set out in in the sun for an hour or so, but have also heard
not to do it because they can go back to yellow in a few weeks. This is the first
time I’ve had to deal with this so any advice would really be appreciated. Thank
you

After some trial and error, I have had success de-yellowing white and grey pieces.
First, wash the pieces thoroughly. I use a clear glass casserole dish or
bowl and fill it with 3% hydrogen peroxide. I put the pieces in and set it on
a LED ultraviolet light panel and cover the whole thing with aluminum foil.
This allows the light and mild heat from the light panel to reflect back into
the container. I let it "cook" for about 6 hours stirring about once an hour,
then wash the pieces again. I learned that removing the pieces sooner would
lead to re-yellowing of the pieces in a relatively short time. Some pieces still
have re-yellowing issues like animal horns and tail ends that have a softer feel
than a brick to start with.
Afterwards, keep your pieces out of sunlight and heat. This is the main cause
of the yellowing in the first place.
