A very bad product for the environment

A bad product for the environment unfortunately promoted and frequently used to clean boats and trampolines. I returned it without using it as I first thought it was misled in believing it was a bio cleaning product.A friend advised me to not use it and then I read the small prints about thecontent of this product. 👎🏻
