Ok guys I'm sure this has been covered..... What kind of preventative maintenance can be done to ensure the removal of an AK-74 muzzle brake? I've tried anti-seize and oil of different kinds, but nothing seem to make this any easier. FYI I clean my guns the same day or the day after fired.

When you clean your rifle throw a bit of CLP or whatever you use on the threads, and maybe that'll help.

The only thing I found is to remove it as soon as possible.
Use a bar through the brake as a wrench, but don't bend the brake.

To help in removal, clean the brake thoroughly with a carbon remover like Slip 2000 Carbon Killer, and use a brass "toothbrush" to scrub the threads on the muzzle. This makes it easier to get off the next time.

I always chuckle when people complain about loose, wobbly AK-74 brakes. A few shots and it's tight.

You aren't kidding they're tight! I use a vise grip to get mine off after shooting and it usually takes at least 30 min.

What rifles do you guys have that have them so tight? My SGL31 is a bit loose, with just a bit of wobble.

Mine isn't very loose.
It's that the surplus 7N6-PS ammo I shoot tends to "solder" the brake on and if you shoot a lot without removing it for cleaning or if you don't clean it soon after shooting it can be hard to get it off.

When I go to the range I usually take 6 magazines with me. I can get the brake off without much trouble, but I clean it thoroughly after shooting, including the muzzle threads.

This. I do exactly the same thing and never have a problem. Scrubbing the threads with the brass brush gets you ahead of the game.
The greatest tragedy is to have the experience and miss the meaning.

Part of my cleaning routine before leaving the range involves spraying water, WD 40 and CLP (in that order) down the gas tube and bore of my rifle. Then I often don't field strip and clean it for a day or more. The brake always just twists off easily by hand when I do. I'm going to guess that the WD 40 and CLP are the reason for this because the threads and inside of the brake are usually still a little wet when I take it off. Give it a try next time, it works well. And of course once you have it off scrub the threads out.

I never had this problem with my 74's or my krink, even if I waited a few days after. Other than a shot of WD40 or kroil to the threads, you could do as others have suggested with taking brushes to the threads to clean them up real good beforehand.

Wellllllll, I never had an issue with getting a brake off until today, it's a freshly painted 105 build, Russian corrosive ammunition, 200 rounds and damn that booster was stuck on there. I suppose that's why those 2 notches are in the front of the booster, I inserted a rod and managed to get it off. Tomorrow I'll clean the threads with a brush and Hoppes #9 to keep it from happening again.

You'd do better using a carbon remover like Slip 2000 Carbon Killer.

This does a much better and faster job of removing the hard carbon inside the muzzle attachment.
