They look clean, however, they feel very stick to touch. I have used soap and vinegar, still very sticky.

If you can remove shelves, take them outside, lay flat, wash with a solution of water/Dawn liquid dish soap, ratio 4:1 or 4:2. Wash down both sides, a scrub brush to insures getting into crossbars, hose off, let dry, replace. Shelves not easily removed? Get a bucket and rag wiping down with this same solution. No scrub brush, water will fly everywhere. You can "rinse" with clean water, but i just dried with a clean rag. Has always worked for me. Dawn dish soap can be used for so many purposes. My go to cleaning solution. Good luck.
