Re: take a tip...leave a tip
Tank cleaning: you guys go to a lot of trouble here, so I'll add to the mix with what I've been doing too long to remember.
Buy BB's or other tiny stuff? Nope! I will either use nuts and bolts, or a short lenght of small chain, chain is best as you only got to pull out one piece and you get it all.
Swish till done, and then I will swish with a bit of rubbing alcohol. Alcohol is cheap, easy and clean, and rarely ever explodes.
I hope this makes it easier for you-all!
