Leave a cup of vinegar on the counter to absorbs smells . also baking soda helps and they have boxes made for it. I find also opening all the windows and doors for 10 minutes in the morning also refreshes the room and removes most smells

The fancy febreeze with the odor sealing-just spray it like crazy when he’s done cooking and it will get rid of the smell for good. (It can be pretty strong through, so get a scent you like)
