Hello there.
Question please:
I was doing some cleaning and went through some old memorabilia boxes, I noticed some autographs are fading. Is there anything that can be used to stop that and preserve them? A baseball ball, boxing glove and one soccer ball have partially fsded signatures.
Items are in plastic containers, I noticed some white dust on a few soccer balls and cover them in plastic, I dropped inside the container one of those humidity packs.
