Subject: Apology for Not Cleaning Your Car

Dear [Name],

I am writing to apologize for not cleaning your car as promised. I understand that you trusted me to take care of your vehicle, and I fell short of that expectation.

I want to assure you that it was not my intention to leave your car in an unclean state. Unfortunately, I made a mistake and did not complete the task as I should have. I take full responsibility for my error and am truly sorry for any inconvenience this may have caused you.

Please know that I am committed to making it right. I will make sure to thoroughly clean your car as soon as possible and return it to you in the condition you expect. If there is anything specific you would like me to focus on during the cleaning process, please let me know.

Once again, I apologize for my mistake and any frustration it may have caused. If you have any questions or concerns, please don't hesitate to reach out to me.

Sincerely, [Your Name]
