Once you have decided to leave the unclogging task to a commercial cleaner, there are a few factors that you need to consider to make sure you get a safe and effective formula.


Without a doubt, you want the cleaner to do the unclogging job effectively. As not all the formulas are the same, you need to determine the using purpose and find a product that meets those requirements.
If it’s for the drain of your bathtub where hair and soap scum are the main reasons for clogging, you don’t need to spend much on a super-powerful formula.

Cleaning Time

Depending on the formula and mess type, cleaning time varies. Stronger cleaners can dissolve elements quicker and unclog the drain within a short time. Whereas, there are some formulas that require a few hours to unclog perfectly.

If you run a business, then go for one that takes fairly less time to clean. For household use, it’s fine to get a cleaner that unclogs within a few hours or overnight.

Safe for Septic System

As these chemical liquids have high dissolving power, if you get an extra powerful formula, it can damage the pipes, septic system and cause corrosion. All the products on the list are very gentle on the pipe as well as septic systems; therefore, you will have no issue regarding it.


Drain cleaners are well-known among the homeowners to have a sharp chemical odor. However, there are some environmentally friendly odorless formulas out there that will have no after burning smell at all.

When the waiting time is over, be sure to flush the drain using hot water. If you still find that the drain is clogged or running water slowly, consider using the cleaner for a second time, as per the instructions allow.
