I have a rack of hooks that sit on the wall that my cooker backs on to, and on this I hang a crowded collection various utensils:

The space is fairly contained, as there are cupboards on either side and the fan/extractor unit directly above. While cooking some pasta earlier they were getting a heavy steaming, which got me thinking... is this storage location safe and/or sensible in terms of hygiene and degradation of the tools? Or any other considerations?
For those without access to the image, or want more info without guessing, the rack holds (in order):
- Two metal handle/clip things for the oven's grill tray
- Metal/Plastic potato masher
- Metal/Plastic spatula
- Plastic spatula
- Plastic slotted spoon
- Plastic spoon
- Metal whisk
- Wooden spatula
- Metal tongs
- Metal/Plastic tongs
- Metal/Plastic Can opener
