How to tell someone to shower more often?

my dad stays with me and he is perfectly able bodied. He is only 50 so it’s not like he needs help. I love him to death and I’m not the type who will sugarcoat things. If I love you I don’t want you to go outside smelling weird. So if his breath stinks I will say “hey your breath stinks. Go brush your teeth.” I would want someone to do the same for me. The problem is I already told him that the house smells like feet when I get home and to take a shower. He doesn’t fully take a shower he just washes his feet but I’m the type of person that I have a sensitive nose so I need to be smelling good smells all day. I even bought him some expensive cologne and body wash but he doesn’t use it as often as I would like him to. If he used it every day it would be gone by now but it’s been about 3 months and the bottles are still almost full. The thing is I leave before he wakes up in order to go to work and I suppose he isn’t showering. if I don’t have work I see him get up and go into the bathroom to take a shower. I just don’t know if he is showering when I leave because sometimes he smells bad. He doesn’t get to the point of smelling putrid but he probably skips two days between showering. So how do you politely tell a family member that they need to shower way more often.
