Good but needs frequent reapplication

It works well for cleaning, but I find I need to apply it every week to keep the rust away completely. Maybe I just sweat a lot on stage.

Perfect gift for guitarists

Bought this for my brother who plays bass. He loved it. The included cloth and brush make it a complete kit. Very satisfied with the purchase.

Great value for the price

Does exactly what it says. My fretboard looks cleaner and the strings feel smoother. Only giving 4 stars because the bottle is a bit small, but it lasts a while.

Keeps my bass strings sounding new

I play a lot of gigs and my strings usually go dead quickly. This liquid really extends their life and keeps them from rusting. The application is super easy.

Essential for humid climates

Living in a humid area, rust on guitar strings is a constant battle. This maintenance agent has been a game changer. No more green gunk on my fingers.

Smells nice and works well

Unlike some chemical cleaners, this has a pleasant citrus scent. It cleans off grime without damaging the finish on my electric guitar. Highly recommend.

5 FAQ

Q: Does this remove existing rust or just prevent it?

A: It helps remove light surface oxidation and prevents future rust. For heavy rust, you may need to replace the strings first.

Q: What is the shelf life of the product?

A: If stored in a cool, dry place with the cap tightly sealed, the product remains effective for up to 2 years from the date of manufacture.

Q: Can this be used on acoustic guitar strings?

A: While primarily designed for electric guitars and basses, it can be used on steel-string acoustics. We do not recommend it for classical nylon strings.

Q: How often should I apply this liquid?

A: For best results, we recommend applying the care liquid after every few playing sessions or whenever you notice buildup on your strings.

Q: Is this safe for rosewood fretboards?

A: Yes, our formula is safe for unfinished wood fretboards like rosewood and ebony, as well as maple finishes.
