A bigger issue is chafe of the running rigging
We remove all our running rigging, each fall. We wash the lines in mild detergent and flake them to dry. After a few days, we coil all the lines and store them in the attic until spring. This procedure doubles the life of our lines. We typically get 8-10 years out of our lines before needing replacement.
The whole procedure is easy and fast to do. This way, each line is inspected 2x a year.
