WB NONMETAL left in horrible state

I also observed the liquid level was so high that both baths were 
almost overflowing at the time I was about to use the bench yesterday.  
When peroxide is added more than needed (which was obviously 
the case because temperature was indicating 130C), it boils quite 
actively and easily gets onto the bench surface.   
In such a situation, it'd be a good idea to wait for a few minutes until

it cools down and adjust to the right amount in the bath first.

Dear Users, 

        Just wanted to send out an e-mail about the poor state of
wbnonmetal. This is directed more to the users who left the wetbech
without cleaning it. I found lots BOE crystals on wbnonmetal yesterday
morning that I cleaned up and today evening I found lots of piranha
drops all over the wetbech leaving horrible brown spots all over the
wetbench. Please make sure that you clean up after using the wetbenches.
Also it took quite a bit of work to blow the water away using the N2
gun. I think the filter in the N2 gun needs replacement.
