Ehum
Ok... I'm
no expert on chipcleaning, (which is probably obvious, but i wanted to be clear on that!

) but i tried to apply some suggestions i've got.
First i filled a small bowl with teppid water and added 1/2 capsule of Ajax All-cleaner. Then i put the chips in, let them soak for a minute or 2 and brushed them thouroughly but gently with a soft toothbrush.
They became clean (sligtly dry and chalky feeling to them, just as they were when i got them initially)
What i noticed though was that one of the chips with an inlay had gotten water under the edges of the inlay. I actually could use my fingernail to catch the edge of the inlay and i could have ripped it off if i'd wanted.
Another chip with an inlay showed no such damage... When inspecting them i got the feeling that the chip that was "undamaged" was coated with something. The chip where the inlay got loosened had a noticeable edge between the inlay and the chip (although they were level). And also the inlay felt slightly different in texture.
The chip with the inlay that came loose.
The chip that wasn't damaged (coated?)
The loose inlay
(I really hope the images will show. This is the first time i try to post pics)
