As long as it's regular Hoppe's. They also make a Hoppe's 9 for black powder. Don't use that one for BH 209.

As for primers. Any 209 primers made for shotguns should work. Get the CCI mag if you can. Otherwise Federal, Winchester, Remington etc should work.

You also want to keep the flame channel clean with any powder, but especially with BH 209. It needs a hot flame to fire. The best way the keep the flame channel clean is to use a drill the size of the flame channel. You don't want to take any metal off when you clean it. Just twist the drill by hand to scrape off the fouling. This is really important to do. I like to do it every 5-6 shots. It only takes a few seconds to do it.
