Yes, I own a detail shop and go through 10+ clay bars per week. Here's a few general tips.

Never drop it on the floor. If you do it goes in the garbage.

Use soapy water to lube the panel well and keep it wet. Do not use water for lube as it dries fast and will stain the clear.

Be sure to turn the clay and stretch it often to expose a clean area.

Do the bumpers and lower portions last as they are the worst and they will cause abrasives to scratch the higher panels.

Do not apply pressure. Let the bar do the work. It is better to go over an area 5 times lightly than twice hard.

Lastly, please do not wash your cars with dish washing soap. Dish washing soap is a degreeser and just as you would not wash it with wheel cleaner, do not wash with dish soap.
