Drano Dual-Force Foamer Clog Remover, Commercial Line, 17 oz

This product was great and very effective. We didn’t have a clog to remove, but we did have an odor coming from our shower drain, particularly in the evening when no water had been run down the shower. We ran 3/4 of the bottle down the shower and 1/4 down the sink drain and it’s completely alleviated the smell. The foaming was very cool to watch. I’d recommend this if you need clog removal, or to dissolve something causing odor.

Drano Dual-Force Foamer works effectively to clear clogs and clean drain pipes. The foaming action reaches areas that liquids often miss and helps restore proper flow. A useful solution for drain maintenance.

Worked for the kitchen sink. Not perfect but the best so far and I've tried about 6 or 7 various lately. I'll buy until I find 100 % effectiveness .

Worked when used in my long shop vac hose that was used to vacuum up the dust from sanding sheetrock mudd. Tape up one end of the hose , pour cleaner, add little water, tape up the other end of the hose, lightly shake the vacuum hose, let it sit for the recommended time, and rinse the hose. Cleaned out all the gunk that was in the vacuum hose!!

Great product. Works as advertised. I was surprised at how fast it works and smells fresh

My shower drain clogged, slowly poured this down the drain & waited a good 90 minutes. Rinsed with hot water & it worked like a charm! I’ll happily buy this again.

Didn't work for me

This stuff didn’t just remove the clog—it evicted it. The foam rises up like some kind of plumbing sorcery, and within minutes, my sink was draining like a dream. Bonus: it smells way less horrifying than typical drain cleaners. 10/10 would unleash it again on whatever’s lurking in the shower drain.

This has become my most recommended product. I like to suggest this
