Vinegar and a spray bottle is cheap. Mix it with water. You might even try red racks or goodwill for a vacuum. Take one room at a time. Don't let it overwhelm you. Any progress is progress. Sally's has gloves in bulk and it might be cheaper than Walmart. Or just wash your hands after you're done and don't touch your face. Vinegar is an odor remover and not a harmful chemical. It smells while you're using it but when it dries it just smells fresh. Dawn dish soap is great for toilets and your shower. I use a dish brush for the shower.
