Because the home remedies are temporary or don't work? I'm not into putting toilet paper or any other crap in my springs which could impede their working properly or returning to the same place very time. Those prices are for a set of 3 springs so unless you use all 5 your done for $10 to $15 and never have to worry about noisy springs again. What did you pay for your guitar? Cant swing the price of 2 sets of strings to solve an issue? The heavy duty red ones are higher tension than normal too so chances are you can do with the set of 3.
