How to clean coraline?

[BozoTheClownfish]

I am in the process of taking down my tank. I've given away all the livestock, but now I need to clean off the hardware.

What is an easy way to soften up / remove coraline from the filter, heater, tank walls, etc?

Thanks,
Wayne

You can give vinigar a try.It cleans calcium deposits,so it should work on coraline.

Yup, a dilute vinegar solution will clean it up. Vinegar apparently degrades rubber seals, so remove them first.
