Welding Tips and Tricks

Is there a technique for getting slag off in tight spaces where you can't reach it with a wire brush?
I have been using fluxcore and stick to burn some stuff together recently and I can't get all the slag off afterwards. I don't want to just paint over it. I can knock it of the bead most times but the yellow-white residue gets into areas I can't get at. Is there a spray or technique to get this off?

Thank you in advance for your help.

Wire wheel on a 4-1/2 in grinder. Get the ones that have groups of bristles twisted togeather there a bit more aggressive.

Edit wire wheel not a wire cup.

for tight areas i normally have a small piece of round bar with the end grinded down to a point. i use it like a chisel. and after i knock the slag off i use a piece of air hose about 2ft long and blow through it to get the slag out.the hose works great for every position just point the end and blow through it.
