I think that nowadays the vinegar we buy at the stores in the US has a strength of 5% glacial acetic acid. We used to be able to get it a bit stronger than that. If you dilute it to 5% you'll be using what we refer to as "full strength" here in the US. If you mix one part of your 24% stuff with 3 parts water you'll get a 6% solution. That should be plenty strong enough.
I wouldn't use the 24% concentration unless you have a build up of crud that can't be removed any other way.
I clean mine with antibacterial soap or in extreme cases of an odor build up I'll use an antibacterial household spray cleaner. I did use vinegar once when I had a build up from washing it in the automatic dishwasher.
I also recommend having an extra tank on hand in case you somehow ruin it by cleaning it with the wrong solution of chemicals.
The most important thing is to not let the water stand in the tank all day every day. I used to do that, changing the water only when the level got low. Even with a brand new tank and distilled water I got a build up of stinky slime.
