Best Way To Clean A 6 Foot Folding Table?

I have a 6 foot folding table. It's like the 6 foot cosco or lifetime folding table except this one is most certainly lower quality. I didn't take an entire picture of the folding table because I currently have a lot of electronics on it and most of you know how these folding tables look.

I posted 2 photos of the areas of the table where I need cleaning. How am I suppose to clean this and what do I use? I have dawn dish soap and baking soda. I also have 70% isoprophyl alcohol. I do not recall what exactly caused those like toothpaste type of stains there. I do eat and drink on the folding table when I use my computer so I will occasionally get water on it. But is that what caused it?

I have many times scrubbed certain areas with paper towel and 70% isoprophy alcohol. Other times I used dawn dish soap and water and paper towels. Is it best to always use a microfiber cloth or sponge for this? Would I be able to clean most or all of these stains out of the folding table? What should I use?

What kind of surface is that? Metal, plastic... what?

If metal, sand down and paint.

Both images appear to be degradation of the table structure, particularly the bubbling/blistering in the first image. The pockmarks in the second image appear to be damage/corrosion, rather than surface stains

If wood it needs sanding down first and if MDF the fibres need sealing before painting. I use water based varnish to seal MDF then sand, prime and paint

What caused that? A Windows update?
