Help! Not sure how to fix/restore this weird porous countertop
So my kitchen countertop (right where the sink and stove are) has seen better days lol. It's super porous and has soaked up stains over the years, so now it looks rough and grimy no matter how much I clean it.
Quick note: the yellow color is actually natural to the material, not rust or stains — but everything else (the texture, the dullness) makes it look pretty beat up.
Honestly I don't even know what this countertop is made of. It doesn't have that shiny granite sparkle, and it doesn't feel like smooth polished stone either. Photo attached if anyone can help ID it.
Mainly trying to figure out:
How do I clean this thing properly before doing anything else?
Is there a sealer I should use so it stops soaking up every spill?
Can I DIY this or should I just call a pro?
Appreciate any help, this thing is driving me crazy 😅
