Belt maintenance

I was wondering what kind of maintenance the belt of my Project RPM 5.1 could need. I've bought this TT one year ago, and I haven't touched the belt ever since (thought the TT has not been through heavy usage.) Should I clean it or anything else? It's a black rubber, flat type belt.

If I know i'm not going to use my tt for awhile ie. vacation,  than I take the belt off. My first belt had a pear shape because I always left it on sitting.

I also remove the belt if I plan on letting my turntable sit idle for a length of time.

To clean my belt, I remove it and wash it in a cup of hot water with a mild soap, like Ivory or a dish soap like Dawn. After that, I thoroughly rise the belt and pat it dry with a paper towel. Some people go as far as using rubber gloves when they handle the rubber belt, but I don't.

Never use rubbing alcohol - it can dry out a rubber belt.

I also have a bottle of rubber conditioner that I sometimes use on the belt of my Technics turntable. I bought it mainly to clean the rubber pinch roller on my Revox A77 reel to reel. It's a mild cleaner and it supposed to preserve and condition the rubber so it lasts longer, but I never tried it on my Rega belt.

Before I put the belt back on, I used a cleaner like 'Cinch' (made by Spic and Span) to clean the sub platter, just to get any grease or belt residue off. Cinch evaporates quickly and doesn't leave a film behind. It also works great for cleaning audio equipment too. I used a microfiber cloth and Cinch to clean my turntable (but not the outer wood trim). It keeps my equipment perfectly clean with no residue, film or buildup.

Thanks everybody.

How much time between each cleaning? After one year my belt looks still clean.

If it looks clean, I would leave it alone. My Rega P25 is about 11 years old, so it has seen a few thousand hours of use in its lifetime. I did replaced the belt about two years ago with an upgraded Rega white belt. I pulled it off and cleaned it about a month ago and it was a little dirty.
