Removing a stain from a porcelain sink can be done with a few different methods, depending on the type of stain you're dealing with. Here are some general steps and tips to help you get your sink looking clean again:

Basic Cleaning:
- Start with a gentle, non-abrasive cleaner like dish soap and warm water. Use a soft sponge or cloth to avoid scratching the porcelain.
- Rinse thoroughly with water after cleaning.
Baking Soda Paste:
- For tougher stains, make a paste with baking soda and a little water.
- Apply the paste to the stain and gently scrub with a soft sponge or cloth.
- Leave it on for a few minutes before rinsing off with water.
Hydrogen Peroxide:
- Hydrogen peroxide can be effective for organic stains (like food or plant-based stains). Soak a cloth in hydrogen peroxide and place it over the stain.
- Let it sit for a few hours or overnight for persistent stains.
- Rinse thoroughly with water.
Vinegar and Baking Soda for Hard Water Stains:
- Mix white vinegar and baking soda to form a paste for hard water stains and mineral deposits.
- Apply the paste to the affected area, let it sit for 15 minutes, then scrub gently and rinse.
Bleach for Disinfecting:
- Diluted bleach can be used for disinfecting and lightening stains, but it should be used sparingly to avoid damaging the porcelain.
- Always dilute the bleach with water (following the manufacturer's dilution guidelines) and do not leave it on the surface for too long.
- Rinse thoroughly after use.
Commercial Cleaners:
- If home remedies don't work, you can try a commercial cleaner designed for porcelain. Be sure to follow the manufacturer's instructions and take necessary precautions.

I’m curious why you are calling them acid stains? From where they are, it would appear that they are caused by mineralization in the water. So, in other words have hard water stains. The way to remove them is typically using a phosphoric acid as opposed to hydrochloric. Sometimes they are heavy enough to require a gentle touch with a pumice stone called pumie. Porcelain is pretty difficult to damage with acid unless someone was using a very strong hydrochloric.
Those are my thoughts, I hope it helps
