Water stains on metal table

I have this outdoor “metal” table as the manufacturer (PHI) states. It is not aluminum because it rusts, but this is not the problem. The issue is the water stains on the top that I can’t remove. Any advice on how to clean it? PS. It is paint coated. Thank you

Foundation stains on white dress from over two years ago. Still possible to remove?

I wore this dress once, never washed it. Some foundation drops got on it and I think I may have tried removing it with water only and just forgot about it. Is it worth trying to remove? The dress unfortunately has no tags to say what kind of material it is; it feels cottony, but could be a polyster blend. Only has a tag that says "Do not bleach. Steam iron. Dry cleaning only. Do not tumble dry." I saw some posts about dawn dish soap and then baking soda. Worth trying? Or will I damage the dress?

What are these spots?

I ordered a few boxes of vitamin C tablets and left them in the cardboard box in my room… I’ve never really examined all the boxes but recently I noticed that some of them have these black spots on them. I tried to wipe them away with tissue but it’s stuck there. When I touch the surface with my finger it feels a little rough. Is this mould growing or is this just stain from liquid that dried up?
