Cleaning playmobil with hydrogen peroxide [H2O2]

(1/7) > >>

Luftgaengerin:
Hi everyone!

I had very good results cleaning some playmobil with the chemical solution "hydrogen peroxide". I guess many of you have already done this, but nevertheless here it goes.

Old playmobil e.g. from the flea market, or after some time exposed to sunlight, gets darker - especially white parts. I found a table from the Victorian set 5323 second-hand and already had one of those in a very good condition. Compare them here:



And this was the result after cleaning:

I was extremely happy with a very old 3771, which got shiny-white, as it should be:

So here is how to do it:

Shopping list:

1) A bag that has no holes (water-proof!) and can be easily and completely closed, as big as you need.

2) SUNLIGHT! (a rare thing in Germany, I could never do this between September and May...  ;))

3) Solution H2O2, or:
English:     hydrogen peroxide
German:     Wasserstoffperoxid
Portuguese :) (@Tahra) água oxigenada

3% solution will do and it's less dangerous, but you'll achieve better results with a 12% solution.

Here's an example from the pharmacy in Germany (3%, 125 ml for 2,50 Euro) :



...and another one, sold as "pool cleaning material" (12%, 1 liter for 8,50 Euro) :

Here's a dolphin who was in need of a bath:

There is no need to fill the bag completely with the solution, because the atmosphere created with the sunlight will do the job. Just shake the bag so that everything gets moisturized.

And let the sun shine on it :) How long? Well, it depends on the measure of the discoloration... We usually left it two hours or more, but the sun here is not so strong, so maybe in the south of Europe 5 minutes will do  ;D ;D ;D

WARNING!! ACHTUNG!! ATENÇÃO!! :omg:

As you could see displayed on the bottles, this solution is aggressive. Don't let children or animals get close to the liquid, even if they are very dirty too.  ;D  Try not to touch the solution yourself, or you will get your skin discolored too, like me  :loco:
