I have a 24g jbj nano that has been in my garage for about a month since I took it down. Do you think it should be cleaned before I use it again? If so, recommended cleaning methods?
Definitely vinegar. if you have a costco membership, you can get I believe 1.5 gallon jugs for under $3 I believe. I'm actually cleaning a lot of my old equipment right now myself with vinegar.
