Sounds like a solution searching for a problem.
Jevans98, I have a masher just like yours. It was my Mom's in the 1950s. I use it regularly, and neither Mom nor I have encountered problems with stuck food. I suggest instead of trying to reinvent the wheel, you clean up your item immediately after using it. No time right then, you say? Serving guests, you say? OK, then put the masher into the empty pot you mashed to potatoes in and add water to cover. Or put a drop of dishwashing liquid and water into a dish pan and soak the masher while eating. The soaking, and bit of arm motion with a scrubbing brush, will keep your masher (and every other kitchen tool) clean as can be.
