Hotter water should help soften the adhesives up to the point where it is easier to remove them so I would use a combination of some wahsing up gloves, water as hot as you can manage to put your gloved hand into to pick out a piece and using a scraper or blunt knife remove the sticker and any excess residue and put it back in the water, preferrably in a separate bowl.
then i would pick the piece out oncei it has time to warm up again and scrub it with a nail brush (or old toothbrush) using white vinegar and soap to remove the remains of the glue.
return it to the water to soak and get rid of the vingegar smell before rinsing.
