Is it legal to use WD40 for fishing?

WD-40 is a brand of water-displacing lubricant used to prevent rust and corrosion. While WD-40 is not specifically designed for fishing, it is not illegal to use it in this context. However, it is important to note that WD-40 is not a food-grade product, and it is therefore not recommended to use it in areas where fish or other aquatic organisms may ingest it.
