Something that'll work a lot quicker than lime away is Muriatic acid. You can get it at Lowes or Home Depot. I've bought it in quart bottles in the past & it's pretty cheap.
Ya gotta be a little more careful with it though. It won't harm plactic at all but I'd recommend wearing glasses & rubber gloves while using it. Just pour about 1" in a plastic coffee can & lower (DON'T DROP) the tips into the acid. It'll foam, fizz & stink to high heaven. Don't breathe the fumes, they will take your breath away. You might want to stir them around a little while they are soaking. After the fizzing stops, you can take the tips out & wash them with clean water and scratch off any remaining deposits. You can safely dispose of the remaining acid by simply washing it down the drain with plenty of water.
