Those blocks are Great good save !! Some of those look like what I have in a stash from the 70-80's.... what would that be retro ??? and popular again, aren't we wearing peasant tops now that were all the rage back then? (ok off topic)
Will be looking for an update that smell is gone !! Baking soda and vinegar both sound like great ideas, wouldn't add them at the same time w/no water, fizzy, fizzy, or funny, funny.... somthing I would do !!
Good Luck :)
