Hello! This is Atiya and on behalf of Expert Village I'm going to demonstrate on how straighten a cabinet. First thing is remove your items from the cabinet and wipe the shelves. As you could see that I have a liner in my cabinets which helps protect the wood you could replace the liner and put your things back in the cabinet. For the higher shelves make sure to have a sturdy chair to reach them. These shelves are wood so also use a special wood polish. This is Atiya and thank you for watching Expert Village.
