Factors Need to Consider while Choosing the Best Drain Cleaner for Grease Buildup:

It’s important that you buy the right cleaner for your purpose. These commercial cleaners are effective at cleaning certain types of clog. Be sure to consider the following things in mind before you buy a suitable drain cleaner for cleaning needs.

Clog Type

Different formulas are good at cleaning different clogs. Cleaners for bathrooms and toilets most deal with papers and soap scum. These might not perform well if you use them to clean kitchen grease clogs.

Therefore, determine where you will be using the cleaner solution. If it’s for cleaning toilets, tubs, showers, and bathroom sink, get one that handles papers and soap scum. For the kitchen, make sure the cleaner dissolves food particles and organic materials along with grease and fat.

Formula Type

Drain cleaners come in mostly 4 forms.

● Liquid Cleaners

These are good at dissolving substances inside the drain that takes a while.

● Powdered Cleaners

The powdered cleaners are for slow-cleaning. These require quite a few times to combat the clogs and make them soft enough to wash using hot or warm water. You won’t get good results for quick cleaning — some need to sit overnight to be able to clean drains thoroughly.

● Granular Drain

These cleaners are similar to liquid cleaners. They both work pretty much the same way.

Safe to Use

As there are plastic or metal made pipes inside drains. Therefore, make sure you don’t end up buying a super strong cleaner just because of its cleaning agents and properties. If the cleaner doesn’t remain gentle on the pipes, you shouldn’t buy it.

Hence, there are safe to use cleaners available in the market that work effectively at cleaning grease and similar thicker substances.

Also, in commercial places, grease traps are another heaven for grease and grime. These areas require more cleaning efforts than others.

How Do You Prevent Grease Build-up in Pipes?

Prevention is the only key to avoid grease build-up in pipes. It’s not that the pipes will clog every now and then, and you have nothing to do about it.

Also, be sure to wipe the foods off the plates before you wash them. Dispose of the foods and scraped materials in the trash. For more convenience, consider installing garbage disposal under the sink. It will prevent the grease from causing the blockage in the drain.
