Boiling Guitar Strings

Have you ever heard of the old trick of boiling your guitar strings? This method is used more by bass guitar players, however acoustic, lead, and rhythm guitar players have used it as well. This little trick goes back some years in the music industry, especially amongst session's players of old. When you boil a guitar string, it causes the string to expand, and thus allows the oil and dirt to be released from the string.

While boiling your guitar strings will make your old, flat sounding strings sound much better, they will not make them sound as new. This is an assumption that many make, but after 25 plus-years in the business I can tell you--this is not the case. However, boiling your old strings will make them sound much better, allowing you to get more use from them. Moreover, boiling new guitar strings before you string them on your guitar will help with the stretching process as well as allow better tone and tension.

Boiling your old, used strings can cause them to produce a much sharper, crispier, and springier tone. You will be surprised at the amount of dirt and oil you will extract from your strings in the boiling process. Once you have finished, the water in the pan will show the results. Below I will illustrate the steps and the process; but first, I will list the items you will need and how to prepare the strings.

What you will need:

  • One set of new or used strings (coiled)
  • One sauce pan
  • Tin foil
  • Regular fork
  • Kitchen tongs
  • A clean cloth towel

A Recipe for Better Sound

Step 1: If the strings you will be boiling are new, leave them coiled. If you are boiling old, used strings, coil them tight enough to fit in to the sauce pan.

Step 2: Fill the sauce pan with water. (Note: Many musicians use regular tap water; however, with the amount of chemicals and minerals that is found in tap water today, I use only distilled water.) Once you have filled the pan with water, place it on your stove with the burner on high.

Step 3: Once the water is boiling, carefully lay in the coiled strings in the water one at a time. (I use tongs to drop the strings in as well as remove them from the water).

Step 4: You should boil acoustic or electric guitar strings for only 3 to 5 minutes. If you go any longer than this, you risk relieving the tensile-strength of the string material. Bass guitar strings should be boiled for 10 to 15 minutes, but no more than 15 minutes.

Step 5: Once the time has elapsed, remove the strings from the water and lay them on a clean towel (Do not use paper towels). Using the towel, dry the strings thoroughly removing as much water as possible.

Step 6: Next, preheat your oven to its lowest temperature. (Shoot for approximately 200 to 225 degrees).

Step 7: While your oven is preheating, wrap the coiled strings in the tin foil (Two strings to a foil) and use the fork to perforate the foil several times. This will allow the air to circulate inside the foil, drying the strings thoroughly.

Step 8: Once the oven is preheated, place the strings in the oven letting them dry for 15 minutes.

Step 9: Once the elapsed time has passed, remove the strings from the oven and let them stand until they are cool to the touch.

Step 10: Restring them on your guitar.

NOTE: There are risks

There are some risks when it comes to boiling guitar strings. One such risk pertains to cheap strings. If you are using cheap guitar strings, you would be better advised to simply purchase new ones. Boiling cheap strings (with their inherently low tensile strength) will make the strings much more brittle, and thus more susceptible to breakage. Also, it is recommended that you boil your guitar strings no more than twice. If you continue to boil strings (expensive or otherwise) the tensile strength will be reduced. Also, another risk to boiling guitar strings too many times is that they will require more tension to stay in tune, possibly causing damage to the neck of your guitar.

The best recommendation is to buy good quality guitar strings, boil them only a few times when needed, and then replace them with new ones. This will keep you and your guitar sounding good while saving you some money.

I live by the sea (salt air -> oxidation) in a developing country (strings harder to find, less choice and more expensive), so I've been saving old strings for years. I am definitely going to try the vinegar, although lime or lemon is a lot stronger, maybe too much so (try it neat on a coin, cold, overnight).

Thanks for the simple tip... I'm a "can't be bothered, will just buy new strings" kinda gal... but... I've been collecting all my old strings to make bangles :) I've decided after reading all the comments that I will boil the strings, then soak a makeup wipe in vinegar and polish them all up once they have cooled

i am inspired with this understanding thanks


Guys I wrote this like 3 years ago and it was satire. You guys are ****ing idiots. I thought I had made it obvious enough; seriously, you guys are more gullible than chicken little.

I wanna try this now!!

Thanks for this, giving it a go after realising all my spare sets are missing the g! Hopefully it'll get me through the gig.

As for Mr Clean, unless you have them fancy 'prosthetic hands' your fingers have oils in them, no amount of washing your hands before touching your guitar will eliminate this.

want to try,let's see if this wierd thing works.
if not ,simple, buy new.

by jo on

Thank You

Vinegar and Water worked Great!

by Mark on

Instructions unclear. Watched pot. Never boiled.

by David on could just not touch your freakin face and hair all the time, and wash your hands before touching your guitar.....

Thanks for the tip! For those who are complaining that it makes more sense to go buy new strings, that is certainly true if buying $6 guitar strings. If you're buying $45 bass strings, you could certainly extend their life this way.

I can't think of anything dafter than going to all that trouble of boiling and drying strings just to save a few bucks. And don't forget the cost of energy used anyway.
Go on, treat yourself to a new set of strings each time!

by RichS on

It is a good trick in case you suddenly need to revive your strings and have no time to order new ones. Beside, I find played strings responds sometimes better and I like when they loose a bit of brightness.

by Marco on


Are people really busting their asses boiling strings to save 5 or 6 dollars?

Wtf? I know you are musicians but damn, can't you deliver some newspapers or something?

You can't be that much of a loser, even if you are a bassist...

Thank you so much for mentioning this! another great tip for bass players

Sorry I misread the notes. Everywhere I said "Travis", i was referring to Keith, the author.

Great article Keith!!! : ]

When I first heard about this about 12 years ago, I gave it a whirl almost exactly as Travis described it above and it worked perfectly. At the time I was playin flat wounds LaBella bass strings and got about 10-12 boilings out of them. Never thought of aluminum foil. Don't think it mattered. Not sure why you're saying don't use paper towel. I've always used paper towel. You probably know something I don't!

Re: the tensile strength issue, I side with Alex above except for the hair dryer comment because they can easily get to 200F. Remember I got 10+ boilings and they still never broke. But I am only talkin about bass strings here. Wih thinner strings I think it'd be an issue of fatiguing the structure of the alloy, but not so much from heating and cooling as it is a relatively very low temp, but rather they're fatiguing mechanically, as in coiling the strings over and over, stretching over and over, restringing, playing for 2-4 months each time, etc.

As a chemist, I also got a bit creative and added plain white vinegar to the pot, maybe anywhere from a couple tbsp upto 2cups for about 4cups total liquid. [thats super potent- I am a chemist - you DONT need that much!!] I've been experimenting with that over the years. Plain vinegar is basically diluted acetic acid. The acid cuts the oils more thoroughly than just water, distilled or not. So you get the thermal and the chemical action breaking down the oils. Tho using distilled agua is a good idea too. Nothing will clean metal better or more quickly than a very hot bath of acid. I've been wanting to try it on a set of old oxidized cymbals. Think of the money you'd save!!! BUT you'd need a really big pot and a lot more common sense.

I'd say, on first 2-3 boilings after heavy playing, I've still gotten brand-new comparable sounding strings. Then as Travis said, quality after subsequent boilings tapers down.

Oh, I haven't used flat wounds in 6-8 years. So all of the above applies to round wound bass strings. .

I've saved so much money over the years.

CAUTION- boiling vinegar can be like turning your kitchen into a potentially dangerous chemistry lab. Be sure your windows are open and ABSOLUTELY COVER your pot. Use a small 2-4qt pot NOT a pan, safer for avoiding mishaps and spillage. Use the stoves vent aka "fume hood".


Don't be a dumby! Even though I'm a bass player [haha] I do actually have a Chemical Sciences degree from Cal Poly in San Luis Obispo.

Bottom line- boil your strings with ONLY plain/distilled water and NOT adding any vinegar if you're apprehensive. If you're daring enough to try a mix of water and vinegar, USE ONLY 1/2c or less for 4c water, even a couple tablespoons will brighten up your strings. Start off more conservative because you're not a chemist. If you want to get experimental and try boiling strings in higher concentrations of vinegar, make sure no one else is home on the first try, especially kids and pets.

Oh, I don't even use more vinegar than that anymore because it's a waste of vinegar.

And I def agree with Travis re: times for boiling. Bass strings 10-15 min.

Great article Travis!

Another obvious risk is that each time you do this, you run the risk of burning yourself. Sounds lame, but seriously, just be careful!
