Security Deposit Withhold to remove tapes

[Winn Vu]

My tenant moved out but left behind 90 little pieces of mounting adhesive tapes she used to hold up shades in the sunroom. They are all over the sunroom metal frames. I tried to remove it without luck (I don’t know the trick). It sticks like gum. I asked the cleaning people to help but they did not want to spend the time even I offered to pay extra. They said it would take several hours and no guarantees no further damages to the paint. What should I do now? Can I withhold like $150 as an estimated cost to remove the tapes but I will offer the tenant to come back to do the job to get the refund? If it’s an easy job, I don’t mind to do it myself at no charge. I don’t like to overcharge her but I really want it removed and have no idea the cost to hire someone. Please help with your ideas. Thank you.
