this also depends on what brand rubber you are using and how much the hop up rubber has absorbed grease/oil.

if there's too much grease/oil, wash it first, and then shoot clean BBs. This will shoot out the remaining grease out of the rubber overtime with exertion of pressure.

if it's a new hop up rubber, just wash it. No need to shoot clean BBs, it's already as clean as it gets after you wash it. Shooting clean BBs won't really help but ya.

When I shoot Clean BB's I notice a huge difference in how clean/filthy the barrel is after. Normally after a game or 5k of plinking the barrel is pretty dirty when using unwashed BB's.

With washed BB's their is barely any gunk inside the barrel.

You are right about the brand of hopup rubber. Different companies use different materials. Some use synthetic RUBBER, other high end rubbers are made of genuine rubber (or a higher ratio of genuine to synthetic) while the low end stuff can be almost anything. I've seen some china brand "rubbers" that had the texture, and finish, and held it's shape like it was made of the same plastic as the heavy duty garbage bags.

I don't see any harm in washing the rubber, and I do notice a change in how sensitive the hopup dial can be. With SCS, Washed BB, and washed rubber it's pretty stupid how much lift you can give a BB.
