Most of the cleaning supplies needed to clean a plastic water storage tank can be found around your house. Deeper, more thorough cleans may require less common tools, and if you can’t reach every corner of the tank by hand you’ll likely need some kind of extender or mop. Cleaning a water storage tank will require the following:

•Floor mop with a sponge head and adjustable or angled rod
•Bucket
•Unscented liquid bleach (non-fiber guard)
•At least two gallons of water
•Disposable gloves
•Eye protection
•Optional: Sump pump, shop vac, wet/dry vacuum, or dry towel
•Optional: pressure washer
•Optional: chlorine strips
