Fablon, fablon everywhere

My poor kitchen is a mess. My ex-tenant has put fablon on the worktops and then put some sort of **** stick on tile covers over the tiles.

Question is what can I do to the worktops? Is there there anything I can cover them with without removing the fablon?

Also, I'm looking at buying splashbacks. Do you think I can just stick them over these stick on tile things?

Thanks.
