Tank cleaning?

[MikeP]

Time to prep the tank for water. This tank sat empty for quite a while and it was not properly cleaned. I need to clean the glass and the silicone. What should I use? Even after I clean it, it will sit for a while before I add the water and rock. Is it best to clean it and fill it right away to get the water circulating or could I leave it for a bit.

Thanks

PS I posted a cleaning question a while ago but only asked about glass cleaning. I got a reply saying to use diluted bleach. This post has a few more questions though.
