Sounds as if the pulley and platter where the belt touches will need some cleaning, and then the problem is likely that the belt is stretched and dry.
Thus the belt needs a bit of ’renewal’.
You can buy a small container of rubber renewal fluid and then soak the belt in that, but only after you clean it.
A second trick I like to use is to buy a 3000 or 2500 or 2000 grit sandpaper (higher is better) and lightly sand the surface of the belt, with some slight low pressure pulls through a folded bit of the sandpaper sheet. do this minimally, kinda thing.
the rubber is drying out so alcohol cleaning is the wrong direction.
First the pulley and sub-platter cleaning, more the pulley than sub-platter.
then the belt sanding, belt cleaning then rubber renewal.
Or just buy a new belt.
If trying to get it done now, then the pulley cleaning and sanding as the rubber renewal fluid is not going to be found in many places. Mostly just electronics component supply shops.
The light sanding renews the surface, and gives you better grip and slightly better flexibility. It may be enough to get by for the moment.
Be careful with the sanding, with regard to potentially creating an uneven thickness of the belt. Wow and flutter will go up if handled incorrectly with too much force and too much sanding. This may stretch the belt even more (low chances) if the job is aggressively handled (higher chances). Try to not round the edges unevenly.
Eg, Linn and others sand their belts to a precise surface characteristic and a precise uniform thickness and even slope profile (cross section view), depending on the manufacturer of the belt and table. This is why a cheap inexpensive replacement belt will work for a Linn table but always move toward buying the proper original Linn sourced table belt.
Whatever the table..if it is a performance table and it is known to employ special or well made belts.....try to get an original or correctly made belt for it. Considering the cost differences, $20-40 more for the correct belt is worth it as the percentage increase in performance can be at least at few percentage points in one’s estimation, if not more. The gains are minimally priced bargains. ’No-brainers", of a sort.
