Main Question or Discussion Point

Found a blue water barrel at a thrift store. It is empty, no order but it held belcline 200 aka polymaliec acid. The barrell will be used to hold food scraps, dirt to make compost. How do i clean the barrel? Water? Or should i try and find another barrel
Thanks

According to the datasheet it is FDA approved for some food processing purposes so it should be safe to use the cleaned barrel for compost. The product is sold as a 50% by weight aqueous solution so water will dissolve any remaining residues. If anything in the container is not water soluable then it is probably some other material.

If there is a bulk amount of the material remaining it might be best to contact local waste disposal authorities .

Hello, I've sent an e-mail to CymitQuimica SL, here in Spain. They ask me if I am a company or lab.

They are going to tell you to throw it out. Poly maleic acid has many many carboxylic acid groups. Deprotonate them and its probably soluble in water. Check that with the manufacturer. Detergent, high pH (~8-9) and heat should clean it out fine. Hot sodium bicarbonate, a squirt of dishwashing detergent and a brush. Wear PP gear like goggles and heavy rubber gloves.
