I started playing squash again after several years of hiatus. It is great fun but one thing that really bothers me is that my old and faithful racket slips in my hand during some occasions. This is especially frustrating when serving the ball and under no stress whatsoever.
I thought about having a small towel with me but it feels silly to run around the court with a towel and wipe of sweat after every second rally.
I can imagine this being an issue that other people face as well. Is it simply a matter of getting a new grip or racket?
I have this problem too. I solve it by using either TournaGrip or Yonex Super Grap overgrips. (Overgrips are wrapped on top of the factory grip.)
Those are the only two grips I'd use for an important match -- everything else is too slippery in my hand.
My friend, who also has sweaty hands, swears by Dry Grip, which is an antiperspirant cream. I'm happy enough with the overgrips that I haven't ventured into the cream situation, but it's another option, and it can be used in combination with the overgrips.
