Kiara SkyDipping Powder Essentials Kit (Steps 1-6,0.5oz)

So this product comes with a brush.. and it cleans other brushes.. so do I just brush the "dirty" brush with this brush? Or do I dip the "dirty" one?

is this really necessary? I´m thinking of getting dip powder but are all steps #1, #2, #3, #4, #5 and now #6 needed? which ones are musts?

Can I use gelish powders with this set?

I destroyed one of my brushes. Is there a replacement brush with the correct fiber that I can replace it with. Like a paint brush?
