I've gone through a bunch of water based hydraulic fluids and found AquaBlue to be by far the best. It's not cheap, the fluid is substantially more expensive than Diamond Shine or KR, but I was having issues with seals leaking/motors locking up until I made the change. Just the feel of the fluid on your gloves is a lot more 'oil like' than the others. Same water-only clean up.
