Before you start pouring sulfuric acid down the drain like a mad scientist, make sure you've done your prep work. Turn off the water supply, because trust us, you don't want to be stuck with a flooded bathroom and a face full of chemical fumes. Also, remove any visible debris or hair clumps - we know, it's gross, but someone's gotta do it!
Now that we've got our game face on, it's time to talk dosing. When using sulfuric acid to clear a drain, you want to make sure you're using the right amount - too little and it won't work, too much and you'll be creating a chemical volcano. A good rule of thumb is to start with a small amount, about 1-2 cups, and see how things go from there. And remember, it's always better to err on the side of caution when working with strong chemicals.
