I need to inspect the wall behind a built-in wardrobe. The back panel of the wardrobe is two flimsy pieces of MDF-type wood held together by a plastic joint - see pic. You can see where I tried to pull the joint out using a pliers but it did not give too easily!
How can I remove that plastic joint? Ideally I'd like to put it and the panels back if everything behind the wardrobe is ok. Thanks.
