Don't let that hold you back. Cleaning liberation is at hand. Buy a safe to store your valuable items, sit down with her to go over shit she isn't supposed to touch (like your computer), label all cleaning bottles in Spanish so she doesn't use your stainless steel fridge spray to clean your LCD TV, and install a nanny cam so you can check up on her from work. You've now insulated your pad against even the most retarded of cleaning ladies.
I should probably do all that (minus the cam, that shit just weirds me out even if it's for me to view and not someone else). I'm just so lazy... which is why I have a cleaner.
