What is the best way to clean dock lines (3-strans nylon)??
And how to make them 'softener??

If the hardness is due to sun and age, there's nothing to do but replace
them. If they're just dirty, a good soak in some mild detergent solution
should do the trick. Sodium percarbonate (oxiclean) shouldn't harm the fiber
but stay away from chlorine bleach. The warnings to never wash rope are a
little over the top in my opinion. Climbers wash theirs, and they have a lot
on the line, so to speak.
