It depends on the size of the fish tank, the type of fish you keep, the filtration that you use on your tank, and whether you are using a bucket method, or have a gravel vacuum that attaches to a faucet
Keep your pump running, if it isn't clear in 24 hours, replace the carbon filter with a new one, it will be clear in the next 24.
Its depend on which fish tank you have small, big. and how fast you are.

You take him out into a ziplock container with water and clean it like a fish tank.
as long as you could in a sewer drain It is cruel and selfish not to clean a tank besides it doesn't take that long get alge eaters to clean up all of that and get a tank filter to help with the mess so it isn't a lot of work.
How long does it take for a oscar to get used to a new tank
Scoop all your fishes to another tank or tub of water and clean the fish tank just as you would normally without the fish
Your fish tank doesn't need to be cleaned. It's always clean.
take the fish out immedietly and drain the water. after you have drain the water wipe the inside of the tank with water. DO NOT USE SOAP TO CLEAN THE TANK, ONLY WATER. after you have done all of this clean out your filter and put a new filter sheet inside of the filter.

depends on the size of the fish, there might not be enough oxigen in a small fish tank.
No. Chlorine will break down on its own...eventually....but it will take days and days. (And your fish would be dead by then.) If you have a fish tank, you need to buy a bottle of dechlorinator - it is not expensive.
