Greasing the spindle will be helpful.
Always keep a good layer of waterproof grease on top of bearing, an apple a day keep the doctor away.
Periodically clean and regrease this top layer of grease, the norm is 3000-5000km*, we suggest common sense approach, you know better how you use your bike.
Sometimes too much chemical cleaning may wash off the protective layer of grease much sooner than expected. Sweat on trainer are unnoticeably caustic.
Please note pairing DUB or 30 spindle to 41/42 bb shell is not ideal, a bit more frequent inspection is advised : every 3 months, 1000-2000km*.
