Yellowish Color on electro polished 316LSST bar

July 23, 2009

The SST bar received electro polish and then after ultrasonically cleaned using MICRO90 cleaning agent concentrated with processed water and air dried. After this process a yellowish color like blemishes appears on the surface.

What do you think could be the cause of this discoloration?

Thanks

Only the people that make micro 90 know what is in it. They should be able to help you with the problem. If not, switch to another vendor. Most companies get serious if they think that you might switch to another product.
