I have the following stains on my toilet
I tried to remove it with bleaching product but to no avail.
I was thinking of white vinegar but not sure if it would work as the surface is wet.
Any ideas are welcomed.

These appear to be rust stains. I've had reasonable success with a product called Wink:
there are also similar products that may be as effective but I have not tried them personally. I do know that chlorine bleach does not work on these.
Be VERY careful with this product, however. It contains HFl (hydrofluoric acid) which is nastier than HCl (hydrochloric acid). Always follow the instructions carefully!
