About This Item

Fuel your strings to last longer and play faster.

Buildup of oil, dirt, rosin, and leftover perspiration can make playing difficult, whether the string isn’t responding to the bow or your fingers aren’t gliding cleanly over the strings during shifts. They can also cause damage to your strings, tarnishing and weakening windings. While a simple microfiber cloth will generally offer sufficient day-to-day cleaning, stubborn accumulated buildup can now be quickly and easily removed with String Fuel, leaving your strings feeling like brand new.

Designed for guitarists looking to keep their strings lasting longer and playing faster, we decided to put this product to the test on a variety of bowed strings. The pleasant-smelling formula easily pulls away rosin, oils, and sweat, leaving violin, viola, cello and bass strings feeling like they just came out of the package. While the tool’s cleaning pad completely absorbs the string fuel formula without any dripping, we tested it liberally on various varnishes to make sure it would be safe and were unable to find any effect, though it does clean and condition ebony fingerboards very well. String Fuel is a hybrid blend of refined naturally occurring oils speed blended with premium quality mineral oils. It is silicone free.

For best results, first wipe the strings and instrument with appropriate cleaning cloths as you normally would after playing, removing as much oil and rosin as possible. Then, uncap the end of the String Fuel tool and run the moistened pad across the full length of each string. Close the tool and immediately remove the dry microfiber cloth from the other end and wipe off the strings to wick away any excess liquid. Wait at least 15 minutes before playing. Use up to weekly or as often as stubborn buildup accumulates.

Dimensions of String Fuel tool: 3.5 x 2.75 x 1.15 inches

Weight: 2 ounces

Made in the USA.

Asked On: 01/12/2019

I am a life-long professional cellist, and I always thought that the removal of oils from the strings is desirable, and used rubbing alcohol to clean the strings & fingerboard. Now this product is putting oil on the strings? What is the reason behind this? Thanks you.

SHAR Answer:

Hello Pamela! The natural mineral oils used in this product are similar to other string cleaning solutions. It is such a thin oil that it acts as a solvent for the other oils and resins that our hands and bows leave behind. These damaging oils and resins trap salt and moisture on the string, causing them to tarnish or weaken over time, so removing them with this formula can help your strings last longer. After applying this product to your strings, the instructions indicate that you wipe them down with the provided cloth, which removes any remaining string fuel. There is no noticeable residue or film left over. I hope this answers your questions!
