Hello, I have a problem with my velvet trays. After some years of use they become dark where the velvet is in touch with the coin. I'd like to ask you if is there any way to restore the original velvet colour. It doesn't seem dirty. Usually clothes can be restored with ammonia. I don't know. Not all spaces are affected from this problem. thank you
There is a fabric cleaner that Might help . I've never ried it but in my search it has popped up several times. Restoration Fabric Cleaner 2lb Canister (ORMD) | Keepsake Quilting
I would take a dry, stiff tooth brush after it first. Knowing that you will be putting coins back in the tray, I would not use any chemicals for cleaning. You might clean one slot with water and a brush and see if that works.
I don't know what type of system yours is but mine has 4 trays to a unit which stack upon each other. If the velvet gets stained, pull out the dividers, cut a new piece of material and voila. I would never use a chemical cleaner for fear that some remained in the cloth.
Looks like that's based on sodium percarbonate. In other words, it's an oxygen-based (non-chlorine) bleach. It's likely to affect the color of the felt. I don't know whether your stains are more from skin oil and dirt, or metal oxides from the coins. If they're metal oxides, oxidizing bleaches won't help. Vinegar might be more effective, but it too might change the felt's color, and it'll leave a smell. What's the construction of these boards? Can they be soaked in liquids, or are they based on something that will swell up and disintegrate?
They are made of wood and silk velvet. It is hard to me to think it is oil, but who knows. Am I the one with this kind of problem on a velvet tray?
I'm not sure there's much you can do about it, then. I have no such trays myself, so I haven't got any more advice...
I've seen at least one other thread, in which someone had old used red velvet coin trays, with round dark areas, where the coins used to be. I don't remember, if the post was on this forum, or on another forum. I also don't remember, if anyone had any good suggestions, about how to fix it.
