Ratified contract or not, if they have not paid the contract performances, then IMO the contract is not valid, and they can pound sand as they have not taken possession of the property.

Would I be able to delete it, the same as deleting unwanted posts on a personal FB page? 

They were afraid to slap him because he was about 5 feet tall and 90 pound dripping wet.  

Several hours later, they were in the back of my truck on the way to the pound and a (not so nice) note on his door informing where to retrieve the dogs along with a 14 day no right to cure notice.

A 600 pound gorilla would struggle to cut it with any sort of knife.The vinyl composite tiles might be a job for a professional if you aren't a handy man.

But having this in the lease may prevent tenants from dumping food/grease in the kitchen sink or unwanted items (toys, etc) from the toilet.

The dog can't weigh 10 pounds.

If it was in poor shape and leaking then ok.I have a rental where the bathroom tile was painted over white from black and gold and it looks great now, however this was not in the wet shower area where looks like yours is so I am not sure of the product you would use to paint over it and how well it would hold up to being pounded with water daily but I'd lookj into that first before ripping that out.

Then start pounding the pavement and following up on leads.
