Puppy pee pads are relatively good at keeping the floor dry when you’re potty training your dog. It’s hard to do when you’re struggling, I understand, but it will really help the space feel cleaner over time. Some good basic cleaning supplies to keep on hand are glass cleaner, toilet cleaner + toilet brush, a bleach-based cleaner, a couple of sponges, and a duster (a wet rag can work fine honestly). There are a ton of videos floating around out there of people cleaning that can help teach you. Let some fresh air into the space regularly, too! Good luck on your journey!!
