Oil Stained Driveway

[Garrett Brunell]

A tenant's vehicle leaked oil on the asphalt driveway of a rental property. The tenant attempted to clean the oil stain using a commercial cleaner, but was not successful. I also tried removing the oil stain by scrubbing it with a commercial asphalt cleaner. My attempt was also unsuccessful. 

I'd like to know if this damage can be deducted from the damage deposit or is it considered 'reasonable wear and tear' to the property? If I try to quantify the cost of the damage how can I go about doing that? If anyone has any tips for cleaning asphalt I'd be open to trying something else. These have been good tenants and I prefer to stay on good terms with them.

This is my first rental property and I'm looking to acquire more and become a better landlord so any tips are welcome.

Thanks!
