If you know how to take the lens out of your mask (it should be in the manual) you can wash it with water. Just dry it off with a cotton towel. Heck, you can wash the whole mask under water and just let it dry, but I'd take out the lens to get all the paint that may be in the cracks. Just don't let it sit on your mask overnight. You'll find that your lens will degrade faster.
As for the mini, Don't put grease on the barrel threads. Unscrew the bolt assembly with the back screw. (Not the one you adjust the velocity with, the one on the back that secures the gripframe to the gun.) Also, make sure the marker is off and degassed and there is no ball in the breech. I know that seems obvious but this is the internet, and you can't assume anything. Take out the bolt assembly, remove the spring, take off the bolt, and then put like dow 55 on the orings of the bolt guide and the bolt. I have this stuff called shocktech gun butta and it works pretty well. That's all you will really have to do as far as I know, just lube all the orings. The reason you can't put gun oils on it is that some aren't designed for orings.

He who knows not and knows not that he knows not is a fool. Shun him. He who knows not and knows that he knows not is a child. Teach him. He who knows and knows not that he knows is asleep. Wake him. He who knows and knows that he knows is wise. Follow him.--Persian Proverb
