Does Anyone Know What These Are?-Strange Plastic Strips In Tanks

[HenryKouba]

I work at a dive shop and recently we've been discovering small plastic strips of varying sizes at the bottom of tanks during their annual VIPS. They're typically about 3-5 inches long, made out of flexible but strong plastic, and have a ridged shape along the top. Please let me know if you have any idea what these are.

Probably from a whip used to remove rust/oxidation. Cleaning fail, however they got there!

Looks like pieces of a tank whip

Oh interesting, that would explain why we've only been finding them in steels
