stinky Ajax dish detergent

[Use Less]

I bought "ultra Ajax triple action with real orange extract" at Real Deals, a combo overstock/dollar store. 28 fl.oz. for $1. I cannot get the smell off my plastic cat food bowls.   I washed them again in hot water, soaked in a basin of water and vinegar. Not much of a bargain; the cats turn away from food put in the bowls. Any ideas?

It's probably not much help but when we had the same issue with soap smell on the plastic spatula things you use in frying pans, the only way I found to get rid of it was to leave them outside for a few weeks... Sunlight rain and bugs seemed to clear out the smell.
