Rental expense deductions

I rent 30% of my home year long and chose to allow TurboTax to calculate correct rental expense deductions for me. This is great for actual shared expenses like utilities and lawn maintenance. However, some expenses (like a new refrigerator for the rental portion of the house and cleaning services for the rental portion) are SOLELY an expense related to the rental. Is there a way to deduct 100% of those expenses while still apportioning 30% of other expenses? I can’t see how to do this.
