Works. Takes a lot of elbow grease. I used a large rubber eraser to put more pressure on the sheets. Helped.

Worked good but should have plastic fret board protectors. Cardboard is kind of flimsy,don't expect to last long.

this lets your frets shiny and clean. its very cool.

This is the best way to polish the frets on your guitar. Steel wool can fly and get caught in the pick ups magnets. Use this and you will not ruin your guitar.

This is the best way to clean and polish your frets. Using steel wool is very dangerous as you can ruin your pickups magnets with e steel wool particles. This comes with a template to protect your fret board, so this can be used on a valuable guitar with no fear of damage or wear and tear.

This product does what it is supposed to do. It does require quite a bit of elbow grease to get the job done, but you will have shiny and gunk free frets when you are done. Would have gotten 5 stars except the cardboard template is a little weak and does get worn away while polishing the frets. A plastic one would be perfect and this would have been a 6 star review then.
