Best Drain Cleaner For Kitchen Sink With Garbage Disposal

Having a garbage disposal unit in your kitchen sink can save a lot of time and energy when it comes to cleaning the dishes. 

Instead of having to scrape food off plates and fish bits of your meal out of the sink, you can pour everything down the drain and let the disposal unit take care of the rest. It all sounds very easy, that is until you get a clog. 

The most common problem with drains and garbage disposal units is clogged pipes. Clogs can be caused by a variety of things, from soap scum, to large pieces of food or small bones left over from your meal. 

If your pipes become clogged, it’s important to get them cleaned out as soon as possible before they cause serious damage to your home's plumbing. This is where a good drain cleaner comes into play. 

Drain cleaners are often sold at hardware stores or supermarkets, and there are several types available, each designed to handle specific blockages. Some drain cleaners contain harsh chemicals for dissolving grease and other debris, but these can sometimes cause more damage than good for your pipes.

As such, it is vital to buy a cleaner that is safe to use with your garbage disposal. You want a product that will break down food and other matter, without dissolving your pipes in the process. 

This article will help you decide what kind of drain cleaner is best for keeping your garbage disposal clean and free from blockages. 

Rejuvenate Disposer And Pipe Cleaner

Rejuvenate Disposer And Pipe Cleaner

The Rejuvenate Disposer has been specifically designed to work well with garbage disposals, so you won't need to worry about it damaging your pipes. This product contains enzymes which help to dissolve organic material such as food scraps and hair. 

If your garbage disposal has a septic tank, then the enzymes in this pod will also work to break down the food waste in it, so you won't need to pump it as often.

Rejuvenate is a prevention product that is used to keep your drain clean, but it isn't powerful enough to remove blockages that have already formed. 

As such, you will want to use it regularly to remove any built up solids in your garbage disposal. Doing this will stop any clogs from forming in the first place, which saves you the job of having to fish them out. 

It is recommended that you run this product through your garbage disposal once every week or two, depending on how much food you put down the drain. 

As well as breaking down any solid matter that has accumulated in your disposal unit, this product can also get rid of any nasty odors coming from your sink. 


  • Lemon scented - This cleaner has a pleasant smell and removes odors from your kitchen sink. 
  • Safe for septic tanks - Rejuvenate breaks down organic matter in your septic tank, so you don't have to pump it as often. 
  • Biological cleaner -  Since this cleaner uses enzymes, it won't damage the pipes attached to your sink. 


  • Doesn't work on clogs - You can't use this product to clear a fully blocked drain.

Buyer's Guide 

Clogged drains can be a real problem, causing trouble for your house's plumbing and creating bad smells in your kitchen. 

If you have a garbage disposal unit, it is vital to have some means of regularly cleaning it to prevent build up of solids inside your plumbing system. Here are some helpful tips on how to choose the best cleaner for your garbage disposal. 

Chemical vs Biological vs Manual

Chemical vs Biological vs Manual

Drain cleaning products work by dissolving hair, grease, and other materials that build up inside your pipes. There are three main kinds of drain cleaners: chemical, biological and manual. 

Chemical drain cleaners usually contain strong acids that break down substances like grease and oils.

Biological products are similar to chemical ones, except they use enzymes instead of acids to eat through blockages.  

Manual drain cleaners are tools that typically consist of an auger-like device for pushing debris through the pipe, or simply a brush for loosening gunk off the sides. 

Manual drain cleaners are generally less effective than chemical ones, as well as being messier to use. However, they are better suited to removing larger objects such as leaves and twigs, which makes them great for getting rid of tough clogs. 

After you have broken up the blockage, you can then use a biological cleaner to eat through the rest of it. As such, it is always handy to have some kind of manual cleaning device for your garbage disposal, rather than just relying on chemical methods alone. 

Chemical drain cleaners are usually made from strong acids, or other caustic solutions, and as such should not be used in your garbage disposal. This is because the chemicals are so corrosive, they can end up eroding your pipes as well as any matter that has built up inside them. 

Always choose a biological cleaner for kitchen drains, as they are great at removing food waste and other solid matter, without damaging your plumbing in the process. 


The amount of product you need will depend on the size of your sink and the severity of the clog. However, most cleaners work best when used as a preventative measure to stop clogs occurring in the first place. 

As such, you will want to buy enough cleaner that you can use a small amount in your garbage disposal every month or two. Doing this will prevent bad smells coming from your kitchen sink, and will prevent the buildup of solid matter becoming a full blockage. 

Cleaning Septic Tanks

Some people have their garbage disposal units connected to their main septic systems. The problem with doing this is that it can lead to an excess of solid matter in your tank, which will require you to pump it out more often. 

If your garbage disposal is linked up to a septic tank, then you should buy a cleaner that is safe for use in these tanks. A good biological cleaner will break down solids, which helps to keep your tank functioning and reduces how frequently you have to pump it out.  

Frequently Asked Questions

What Can You Put Down A Garbage Disposal? 

Garbage disposals must be cleaned out regularly, as food scraps can become stuck in the blades if left too long. 

Oils and fats can form a thick paste that will make your garbage disposal clog up. Pasta, rice and other starch-based foods can also be difficult to clean out since they swell up to form a sticky mass. 

You can still put all of these items in the disposal unit, but doing so may mean you have to clean it out more frequently. 

Keep items like banana peels or hard items like fruit pits out of your garbage disposal, and avoid putting nonfood items such as paper scraps or cigarette butts into it as well. Coffee grinds are normally fine but can still accumulate at the bottom of your unit to cause a clog.

Is It A Good Idea To Connect A Garbage Disposal To A Septic Tank?

Connecting your garbage disposal to a septic tank is convenient and can save you having to clean it out as often. However, this will lead to more solid matter building up in your septic system, which means it will need to be pumped out more frequently. 

As such, it is better to not connect your garbage disposal to a septic tank, unless you have a suitable biological cleaner for breaking down the solid matter that will accumulate in it.
