I have to (ugh!) unclog a drain in my guest bathroom tub. It rarely, if ever, gets used. I have family coming on Friday, and the water drains super slowly. A colleague told me to boil a large pot of water, then pour it down the drain while it's still boiling. Has anyone successfully tried this method? I've tried Draino three or four different times, but to no avail I'm starting to think that BF is going to have to hit Home Depot for a drain snake. Any advice/help would be appreciated! I'll try anything at this point, LOL!
