Insta-Flo Crystals Drain Cleaner 1 lb.

I started using this product on the advice of a plumber many years ago. I do like the cleaning action it does and use it monthly and have been very satisfied with the results. I just was never satisfied with other products you buy at grocery/hardware stores. Some times you can find this at some hardware stores or big box stores; but I got tired of looking and just ordered the package of 5 and keep one at each sink area. I do have to cover my nose and mouth, usually with a washrag or something, as the powder does bother my throat and nose. It doesn't take long to do its work and can tell when you quit hearing the noise it makes.

Best I have found for drain clogs. Follow instructions and keep your nose away as there are strong odors.

Excellent product. We use it extensively in our apartment buildings.
