Sadly, none. My boys usually have a pink nose 1 day of the month: bath day lol! It’s usually clean for a day maybe 2 max before they’re brown again. I’ve heard some people have luck with putting a tiny bit of coconut oil on a cotton ball and wiping the nose with it! I just say it’s adds character
We are cleaning his ears once a week & his eyes/nose everyday. He enjoys being cleaned. Ear cleanings are his favorite! He is also very non-greasy. I read about other sphynx owners dealing with "grease streaks" on stuff, but he has a very light peach fuzz and it seems to wick it away.
