A pond, but not recommended for beginners.
How do you get the fish smell off??
Amonia based window cleaner can be harmful to electric parts. I use a little rubing alcohol 2 or 3 ounces, dawn 1 ounce and water to fill the bottle. I always use the T.L.A.R. mix method......That Looks About Right

Also just throw an old bath towel in with the planes and wash it once a summer weather it needs it or not instead of paper towels.
