With the price of salt on the rise it may be a good move to just replace it.
Salt savings alone would be a good plus.
Good Luck.
that's a good point. I usually just go to Sears Hardware and buy 4/5 bags at a time for like 20 something bucks but if you add up what it costs in a year, it's not insignificant. Today I'm scheduling the install for next week.
