Fachgerechte Entsorgung des Wasserstoffperoxid wäre hier angebracht. Und natürlich das Wiederverwenden wie zuvor schon angemerkt. Ansonsten super Ergebnis!
That blue plate I'm glad you restored the color, but it would've been an excellent piece to use as like a grass plate with the exposed blue area as a little river.
Warum wurde das Wasserstoffperoxid weggeschüttet und nicht für andere Gegenstände wieder verwendet? Ist meine Meinung nach, eine reisen Verschwendung, da alleine der Kanister vom Wasserstoffperoxid teurer gewesen ist als das LEGO, was man wieder hergerichtet hat.
You bleach these parts, but that's not restoration. This kind of treatment does not stop the degradation of plastic, and worse, it can only accelerate it.
How do these pieces look today? They usually become brittle and yellows again after this method. It’s mostly used to scam collectors to buy what looks like pieces in good condition.
It's even worse. Yellowing is a sign of chemical instability and plastic degradation. I don't know about peroxide, however exposure to UV has the effect of accelerating this degradation. So even if he success to bleach these parts, he dont not prevent them from yellowing, which will occur more quickly than before. And it's not just an appearance problem, because this degradation also impacts the elasticity of the plastic. The pieces will lose their hold and become more breakable.
