My sister is taking down her pool and gave me all her pool chemicals. Included in the "pool stored" stuff, she also gave me a jug of Champion Pool Winterizer which had no list of ingredients on it. When I googled it, it came up "Quaternary Ammonium Compounds" as the ingredient. Further searching resulted in websites and pdf documents
Is there any benefit in using it or should I toss it?
Thanks for your input,
