How much of my rental expenses can I deduct for a home I also live in?

In 2021, I rented out one bedroom in my 2 bed, 2.5 bath condo while living in the other bedroom. I had a number of repairs/expenses for common areas. Would I be able to deduct 100% of these or only 50% of these expenses?

Expenses include:
- Purchase of new microwave vent grille
- Repair of fridge leak
- Supplies to clean water softener
- Supplies to clean hard water from toilet in the half bath
- Supplies to repair kitchen grout (there were cracks)
- Supplies to re-stain kitchen cabinets (the wood was damaged)

Thanks in advance
