Hmmm....picture? Either way, a grinder or a dremmel tool should be able to get rid of it, be sure to re-passivate it afterwards however. A quick google search will tell you how.

Thanks I'll post a pic later today. While seaching the web
I found this product Derustit SS-3

Stainless Steel Cleaner

Nothing Cleans Stainless Steel Better
Derustit SS-3 is a powerful, ready-to use cleaning solution formulated specifically for stainless steel. Use it to remove slag, scale, and tarnish on large surface areas. Derustit SS-3 is especially effective in the cleaning of light or heavy heat scale and tarnish that forms on and around weld beads.

For Stationary or Immersible Applications
Derustit SS-3 is available in liquid or paste formulations. Each is equally effective on large surface areas and weld beads.

Derustit SS-3 is ideal for industrial use:
Food & Beverage Processing Equipment
Medical Equipment
Chemical Processing Equipment
Waste Water Treatment Plants

Pickling and Passivation

Pickling: Complete removal of oxides, carbon, scale and other impurities from stainless steel.

Passivation: Regeneration of the protective surface to resist corrosion.

Derustit SS-3 Stainless Steel Cleaner - in liquid and paste form - is a carefully balanced formulation of effective pickling agents combined with special inhibitors.

This stuff is'nt cheap I hope it works! Hoping not
to have to grind and make thing worse.

Hey "Retail" - I'm wondering if the Derustit SS-3 Stainless Steel Cleaner works? I have a keg that was converted and it's developing a small corroded area. The corrosion is not in the welded areas but this stuff may work anyway since it's basically made from a few different types of acid.

I've used a product called Ospho but only on the exterior of the keg since it's not made for food and beverage use. It's made with Phosphoric acid.
