Since WD-40 is water based it will dry up nicely and will not harm the rubber the way petroleum based lubricants can. Technically, since it evaporates and is water based, WD-40 sucks as a long term lubricant.
WD-40 isn't and never was intended to be a lubricant. It's also not water based. It's an extremely light petroleum based oil used as a 'water displacer' (That's what the WD stands for, kids) and since it's lighter than most oils it cuts them and evaporates, making it an excellent degreaser.
The quickest and cleanest way to get grips on and off is with a compressor, get the nozzle between the bar and the rubber and fire away. On and off in 2 seconds, no waiting for anything to dry, nothing to gum up when the grips get hot.
