Woul it be wrong if I didn’t confront my aunt about her bad hygiene while cleaning bathrooms?

I live with my mom, and my mom is paying my aunt to clean the bathrooms. I happened to be home today when my aunt came. She forgot her gloved, and I watched her open the toilet lid with her bare hands, and put cleaning products to soak in it, then she would proceed to wipe down the sink. I suppose if she didn't touch the rag on the side she wiped down the sink with then its no big deal, but I told her anyways, I said that at my job (I work for a commercial cleaning company) that I was trained to clean the sink first, and not even touch the toilet until I'm done with the sink. She agreed, but then I heard her do the same thing in another bathroom. I'm afraid to say anything else, because I don't want to her to get mad at me.
