just say to him "if i had a boogie hanging out of my nose as my mate i would want you to tell me or food stuck in my teeth" see wat his re-action is then just say well as your mate dont take offence but have you tried links deoderant its what my fella uses and it smells great it lasts all day as well if you have a shower before you put it on.

Thats what i would say dont make a big deal over it make it light hearted see how you go from there.
