Collection cup stained due to Tunze epoxy ?

[gregzz4]

All the 'scaping is done, but now this
So how do I clean the stains from my cup ?
Do I run it in the sink with vinegar for awhile or what ?

I won't be surprised with a limited amount of replies this long weekend

No thoughts yet ?

yup... soak in vinegar solution over the next day or 2, then should come with quite easily.

Thanks, I was afraid of that
So, in other words, I have to take it off-line for a day or more to clean it ???

In that case, I may as well run it in a tub of vinegar, right ?

If you can find it, there is a cleaner called Alconox. It's a white powder that comes in a milk carton like container. Mix 1 spoonful for a gallon of water (not tank water). Should clean the epoxy residue no problem with a bit of a scrub and washes away completely clean. I use it for cleaning serious crap off my glassware in my lab (like stuff that is considered very permanent) but the soap leaves zero residue.

If you can't find it, I can see if I have some left in my lab and I can toss you a bit.
