230k Camry Upkeep

I am in love with my 93 Camry V6 XLE. Need some info on how to clean the headliner which is dirty from years of riding with the roof open. I thought of spraying it down with a cleaner and vacuuming it while damp with a shop vac, but have fears of it hanging down like a 86 Cadillac eldorado. Please HELP!!! :dunno:

I'd wipe it down with a "damp" cloth. Other than that, I wouldn't do much else. If it gets worse have it replaced. Please don't drive around with the GM 80's look of sagging headliner.

Blue Coral makes this stuff called dry cleaning upholstery cleaner (or called something to that effect). I have found it works miracles on everything. You spray it on and use a brush to scrub it and it makes it look like new. You don't have to dry it or anything. Just let it air dry. My wife's seats and carpet were trashed. They look great now...or at least until she gets in the car again. BTW, it is a clear liquid.
