Getting a lot of pops & crackles

I’m using  Linn Sondek turntable with an AKG cartridge and, of late, I’ve noticed a lot of pops and crackles on records which previously sounded pretty clean. Could this be due to the cartridge getting old?

What condition do you think the stylus is in on a 30+ year old cartridge? I doubt it is good!
Would a worn stylus cause pops and crackles?
Also, the pops and crackles decrease appreciably if I play the same record again immediately. Maybe playing it the first time clears some of the dust. Is that possible?
What exactly are you doing, cleaning-wise, with your records, stylus, and platter?
Simply try another cartridge, you can invite someone with different cartridge if you don't have another cart at home ? Pretty easy

You can also play some new record or anything in MINT- condition to check

You'd better use this brush before you play any record.
Zerostat is also nice
