HI all
    I was changing the chemicals in the left sulfuric peroxide hot pot when I espied a piece of silicon at the bottom of the pot. Also, the 6:1 BOE bath was open and white residue all along the inside of the bath. The cover was lying face up on the bench.
Just wanted to point these out.
Cheers
Girish
