Cloudy haze left on Stainless
Hi all,
Just wondering if anyone has a solution to my problem. My pans soaked in vinegar for months, for the most part cleaned up perfectly, but there is still a dull haze left on the stainless that I would like to remove. Ive used vinegar and rinsed with water and scrubbed them down, added water, boiled and rinsed, etc....still a dull haze.
Any solution to this or should I accept it is "normal"? The outside of the pans are still a mirror finish.

I can't help, I've never soaked the pans in vinegar for more than 2 days, usually just overnight. I didn't get a haze. Is it possible you left it so long that the acid actually made a light etch in the SS?
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
You could try a caustic based cleaner and see if it helps. Organics clean up better with caustic and minerals with acid.

Try rubbing with a paste of baking soda/water. Rinse copiously. If that doesn't work, try a little alcohol.
It might just be permanent. Acids (even a relatively mild acid like vinegar) shouldn't be left in pans for extended periods. You only want to leave cleaners in place long enough to do the job.
