+1 Yes, my first thought as well.
I will admit to being lazy. I want to do the least amount of work as possible (I worked 75 hours / week for over 45 years)… if I see some fuzz on the needle I’ll use my KAIU Anti-Static Turntable Stylus Gel Cleaner. I use as infrequently as possible. Don’t really notice a difference before and after. I used to use Last, never lost a needle.
