This gel really works! I have very old albums that even a centrifuge cannot clean well enough to get rid of the pops and crackles. While this gel is not 100% effective, it works great when used correctly. Don't smudge it, just dab it on the surface or roll it over the surface leaving the gel bead intact. A quick clockwise wipe with the included microfiber cloth after using the gel will definitely improve the sound of your album. Again not 100% but it helps.
