Am I considered pure?

in general using soap and a like is ok if you find that water alone doesn't remove the smell so you do a normal shower using these substances (soap and a like) then you do the ghusl and for that here is a good article about how it is done:

If you see najis in you body visible then you are not pure and the have to do ghusl again. If you just get smell of najis and don't see anything in your body you are pure.
