Most cleaners will get rid of the soap trash, but if it's to the point that it's white and chalky, you're probably going to have to use some sort of scrubber that's a bit abrasive. Otherwise, you'll freshly need profoundly of 'elbow grease' to scrub it off next to a sponge or something less rough. I use 'The Works' cleaner myself.
