Here's a tip from the Volume 4 - Issue #5 issue of RodMaker magazine:
Ceramic guide rings are great. They are slick, hard and strong and can
last forever. They don't fray the line and don't get cut and grooved. But
they are not indestructible.
I have found it is a good idea to frequently check my guide rings for tiny
cracks or chips that might escape my over-40 eyesight. I just take a cotton
Q-tip swab and run it around the inside of each ring a few times each season.
If there is a chip or even a slight crack, it will trap some of the cotton Q-tip
fibers and pull them from the swab. You can easily see these trapped fibers
as they are usually pretty long and will be trapped deep in any crack or
chipped area of the guide." ~ Walt Reminger. . . Fort Bragg, CA
