How to clean out Plastic Water Barrels??

Question

im getting one of those blue 55 gallon plastic water barrel that im planning to use for drinking water. but the thing is, it used and it used to contain pet shampoo of some sort. how can i clean it properly to get all the gunk out? is bleach safe or would it make it worst?? thanks

Answer 1

Scrub well with soap and water. Then use a 50/50 mixture of bleach and water to sanitize it.

Answer 2

Some kinds of pet shampoo contain pertinans (spell?) which are a poison. If it were me I would not use that barrel.

If you can find some that were used with Simple Green or other 100% biodegradeable ingredients then I would consider using them.

As for proper storeage mix of water in 55 gallon barrels. 1/4 cup per gallon will keep the barrel for at least 3 months. It must remain sealed and kept cool. Then at the end of the three months empty the barrel. Reclean it with 50/50 bleach solution of about 5 gallons Rises twice and refill with the 1/4 cup per gallon of water solution for storeage again.

I have three in my shed just in case. Plus I have a swiming pool to wash with so I am well covered.

Answer 3

Bleach will work but you need to ask yourself a few questions first:

Will I drink all this water within a few days?  Standing water not cooled enough or hot enough will grow bacteria and make you sick.  Saving water is fine if you vacuum seal it or keep it frozen.
