Countertop stain - security deposit question

[Victor San Gil]

Hi Everyone,

I had a construction company rent 5 of my units with 4 guys in each unit. They moved out last week, but I found out that the counter tops have been stained due to the tenants not cleaning their unit. Here's a picture of the countertop: Countertop image. The stain is the dark area on the countertop and we have tried many cleaners and hired a cleaning company to try and remove it, but no luck. Is it wrong for me to charge the tenant the full price to replace the countertop?

Thanks in advance!
