Acetic acid can be very agressive to some stainless, so watch out.
We used a 20 % by volume Glacial Acetic Acid in water at 100°C on 304L S/S with no Problems. The corrosion rate was not measurable. We limited the time of exposure to 4 Hrs per cleaning. We actually used the 20% Acetic Acid on 304L at 220°C under pressure for short peroids of time with no problems.
Remeber to keep your concentration and temperature as low as possible. Acetic Acid doesn't have very good wetting properties so you may have to add a wetting agent.
Heating the acid will create a lot of fumes. The exposure level for Acetic acid has been lower so check on personnel exposure. I don't know the new TLV but it has changed the methods we did use.
