deoderants

What are you guys using to deoderize the anus...if anything. I use lotion and powders but I am wondering if that is good for the skin there. I tried using the crystal body spray down there but it stings. It does work well for the armpits, pubic area and feet though. Is there anything else?

Also is there a fail proof method to wiping completely after a bowel movement?
I wipe until there is nothing on the tp but there is still the smell there.
I wet the tp, use deoderant soap...it's still there. The smell is definitely coming from my arse leading me to the conclusion that it is less of a medical issue and more of a hygiene issue.

Correct me if I'm wrong but it's not possible to smell anything from the inside of the body thus it has to be on the surface of the skin...and if it's not emitting from all of the pores or a whole region of the body then it is not likely to be systemic.

At worst there could be some leakage caused by an unhealthy colon environment, but I'm working on my diet and taking chlorella. I am also taking skin vitamins.
