Drano Max Gel Clog Remover

Drano Max Gel Clog Remover

Drano has been around the sink and tub when it comes to drain clog cleaners. And at a reasonable price for two 80 oz bottles, Drano Max Gel Clog Remover is super affordable. In addition to working quickly, it sinks right through the standing water in your tub or sink. And, it won't corrode your pipes. However, you have to give it a little time to work. According to the package, it takes between 15-30 minutes. However, if you add a bit of boiling water to the mix, the two definitely work faster.

Like Drano, Green Gobbler is advertised as safe for pipes and biodegradable. It comes with a price tag of $9 for a 31 oz bottle.

Bio-Clean Drain Cleaner

Bio-Clean Drain Cleaner

If you are looking for a clog eradicator that goes to the septic level, then Bio-Clean is your go-to. Rather than acids or lye, Bio-Clean uses bacteria and enzymes to cut the hair, food, grease, soap scum, and grime out of pipes. And, this two-pound container has about 100 treatments making it cost-effective.

Just remember, this is a clog decomposer that can keep your pipes running smoothly. Therefore, the treatment takes days, and it's not designed for instant clog removal for a completely blocked drain. Instead, using this as recommended can keep your pipes working and prevent clogs in the future.

Liquid Fire Drain Line Opener

They weren't lying when they called this drain cleaner liquid fire! Liquid Fire Drain Line Opener is a fast-acting cleaner using sulfuric acid to pop through those clogs. One of the benefits of this cleaner is it works fast. Therefore, you only have to wait about 15 minutes or so before your pipes get moving again.

However, given that this is sulfuric acid, you don't want to pour it down aluminum or galvanized steel pipes. And, you might want to think about keeping it away from your sinks by using a funnel to get it into the clogged pipes.

In addition to working in the kitchen, it's recommended for use in fountain beverage drip trays and urinals. It's also designed to get rid of those irritating drain flies. However, since this is a natural cleaner, it's not going to be as effective on big clogs.

Tips for Using Drain Cleaners

While these are some of the best drain cleaners on the market, here are a few tips for unclogging your drains.

  • Follow the instructions. Even the greatest cleaner isn't going to work properly if you don't follow all the instructions.
  • Pay attention to warning labels and recommendations for ventilation and safety equipment.
  • If hot water is recommended, try boiling it. This can be a deal-breaker for getting some clogs moving.
  • Drain cleaners don't mix. Therefore, if you are trying more than one method, ensure the previous method has been completely removed first. This includes homemade clog removers.
  • If commercial cleaners worry you, try a natural method like vinegar and baking soda first.
