Although they're mentioned here as a vessel for fermentation, please stay well away from glass fermenters, especially bigger ones. Nothing wrong with a 1/2 or 1 gallon jug, growler and such. Even they can cause serious injuries when they break, sharp shards of glass.
But anything larger can become a real hazard. Especially given shoddy manufacturing standards in some countries, and the lack of any QC. So in general, avoid glass carboys (vessels) larger than 1 gallon.
At homebrew level we have much better alternatives now than ever before.
There's no reason a brew bucket should ever get scratched.
It's not that you're hauling rocks in that bucket one day and the next day you decide to ferment a batch of beer in it.
Soaking is your friend when it comes to remove stubborn caked on krausen, etc., Brushing is usually not, unless you know what you're doing.
Although a softish nylon brush can be used, it's generally safer/better for the plastic to only use soft washcloths to mop cleaner or sanitizer onto the surfaces. And again, soaking with a little (cheap) washing soda added.
IMO, Oxiclean is highly overrated. Although I must admit, it looks good on TV, so keep it there.
What cleaners and sanitizer will you be using?
