I will agree with using *the works* on toilets, but I like a hot bucket of water with some dish soap in it. Cleans well, cuts through grease though you might have to rinse with clean water if you use too much soap so be careful. The bleach in some dish soap will be enough to calm any worries. Wash everything fabric you can in the washing machine. If it is cold there, use windshield washer fluid on the windows..cleans really well, and it will not freeze when doing outside ones. Spray down the tub/shower with a good cleaner and allow to sit for fifteen minutes or so before starting to wipe down. Cleaners need time to do what they are supposed to do. I don't bother spending tons of money on unnecessary cleaners..I like dish soap and water..safe on sealed wood and safe for antiques (just do not wash antique glass/ceramics in really hot water..make it cooler). Oh..and be kind to your father..this is his home no matter how you might feel about the state compared to your home..respect him and his home please.
