Hi all... I have now tested out my second hand hex, and all is water tight, its hasnt had fish in it for many years, but those it did have all were ill or died etc... Its been swilled, and washed out a few times now, but I would like to nuke anything remaining one time.. any suggestions?
I have looked for a pinned tank cleaning thread or FAQ etc, but cant find one.. a linkage would be great if I am being too silly to spot it!

Thanks

Hot water,and vinegar should do the trick-just rinse it well.

Thanks Devs Any old vinegar do?

White vinegar works better than apple cider vinegar

Thanks! i'll try and get a bottle tomorrow
