 can just see it now, IBCs with their "cages" off 
Sorry to bring this post up again. I now have an unlimited very cheap supply of IBCs thanks to a close friend. Unfortunately he's just said they have had water based Varnish in them. I've tried searching the forum and had one topic relating to water based varnish, but it lead no where.
Can it be used? After the obvious clean.
I know its a touchy and skeptical topic using IBCs that have had chemicals. There really needs to be a sticky on this. Debunking myths etc. I guess there needs to be some real investigation by contacting schutz and those industrial companies who clean and recondition these, into what chemicals "lock" into the plastic, or do they even get absorbed into it?
Then perhaps the methods or process they go through to make sure its "clean" and cleared to be reused.
Then do a sticky based on a consensus of information from members who have had exchemical and even some hazardous food grade ones (acids, additives etc).
What to definitely stay away from;
Where to possibly find safe ones (drink/food manufacturers);
What was in them(perhaps references to msds too);
Is it safe to clean/use;
What is safe to clean it with;
Is there something to use to split/ break the chemical down;
And list the methods of cleaning (triple clean, sit til algae (does it need it?) Steam clean etc.)
It would put a lot of people out of forum searching misery, and perhaps squash a lot of skepticism on using them.
Sadly not everyone is handy to "safe/foodgrade" ibcs at our doorstep, and theyre more widely used for transporting chemicals. Even sourcing them could mean massive freight cost.
We all need this sticky. 
Anyway, is it ok to use the water based varnish ones?
