When mechanical methods fail, many people use chemical drain cleaners to unblock a clogged or slowly flowing drain. While these products are useful in both opening drains and removing buildup, they can be harmful if misused and can cause potential property damage. Knowing the proper way to use a drain cleaner is important.
Steps
-
Understand what drain cleaners do. Chemical drain cleaners or openers usually rely on a strong acid or alkali to do the job. These substances both break down and dissolve the clog, and react with the water to form heat.
- Drain cleaners work best on slow moving drains. They are less effective in clogs with standing water.
-
Stick to using drain cleaners on the right kind of drain. Drain cleaners are not safe for use in toilets, tubs, garbage disposals, or in fixtures with a macerator or grinder pump.
- Drain cleaners are not recommended in houses with a septic system, as they can kill the bacteria inside the tank that help break down waste.

Pick what kind of drain cleaner you want to try. Most drain cleaners are either a concentrated "gel" or granulated crystals. There are also special types of drain cleaner for special jobs.
- Some products use a two part formula to generate a kind of "foaming" action. These are good for removing buildup, but should not be used in a completely blocked drain.
- Enzyme formulas exist, which attack the protein and fat bonds of clogs. These are safer and can be used on toilets and tubs, but are slower and less effective.
- Heavy-duty formulas usually contain 100% pure lye or sulfuric acid. These are effective but can be highly dangerous to the untrained.

Follow the safety precautions. Drain cleaners are caustic and can cause harm to skin, eyes, and mucous membranes. When using a drain cleaner, wear safety goggles, rubber gloves that extend beyond the wrist, and a face mask or respirator if applicable.
-
Use liquid drain cleaners like this:
- Open the bottle while grasping the handle. Do not splash or squeeze.
- Pour the specified amount into the drain.
- Allow up to 30 minutes for the clog to clear.
- Flush with plenty of hot water.
-
Use these general steps for powder/crystal drain cleaners:
- Remove any standing water.
- Add 1-3 tablespoons of product into drain.
- Add one cup of cold water.
- Allow up to 30 minutes for clog to clear.
- Flush with cold water.
