Drano Dual-Force Foamer 500mls. Commercial Line

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

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.

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.

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!!
