Why it is important to dispose of mop water correctly 

Everyone knows mop water is a waste of cleaning, which means it carries a lot of debris and harmful things that we want to remove from the floor. So, dumping mop water is an essential thing that we need to do after cleaning.

But that doesn’t mean you can just pour mop water anywhere you feel convenient to do so.

If you dump mop water at the wrong place, the harmful bacteria can crawl back into your house, destroying the effort you made when cleaning. That won’t be a pleasant result. 

Moreover, if you use chemical cleaning solutions, the wrong disposal of mop water can badly affect the environment, which will come back to you sooner or later. For instance, the botany where you dump mop water that contains chemicals will be damaged heavily.

That is why using a proper method to dispose of mop water is something you must know to avoid contamination and prevent health illnesses.      

Where mop water should be disposed of

Now that you know the importance of proper mop water disposal methods, let’s see where is the perfect place for dumping this waste.

But first, you need to protect yourself before doing this task by wearing a mask, gloves, and even goggles. That will minimize the effect of chemicals in the mop water on your skin and senses. Even if you don’t use chemicals for mopping, wearing protective gear is always recommended.

When you are ready, find the nearest spots out of these to get rid of the mop water:

1. The drain

This would be the most accessible place to go for dumping mop water. Your drainage system usually adjoints the underground sewage system, where wastewater will be treated in a professional way. 

It is okay to dump mop water with small debris like dust into the drain because it won’t cause clogs in your plumbing system. But if there are fur dander or hair clumps inside the mop water, make sure to fish them out to throw into the trash bin before pouring the mop water into the drain.       

2. The open sewer

You can dispose of dirty water by pouring it into the open sewer because this thing is created for the proper handling of wastewater, which means it is also perfect for mop water. 

If you usually use chemical cleaning solutions for mopping, then you should find an open sewer near you to get rid of the mop water. That way, this intoxicating waste won’t have a chance to affect you and your family’s health.

3. The bush area

If you happen to have a garden, you can pour the mop water into a bush area. The dirty water can help kill wild weeds in your garden, and it can happen faster if there is a chemical cleaning solution in the mop water. This is a great way to kill two birds with one stone.

However, you need to consider whether this is a suitable option or not if you have pets in the household. Your pets may lick or eat the wild weed (cats usually do that if their digestive system is not in a good stage) and get poisoned or have the dirty mop water on their paws, then drag it back into your house.      

4. The plastic bag

For those who can’t dispose of mop water directly at any spots recommended above, you can pour it into a plastic bag and seal it to throw them out with the garbage. 

Try not to leave the bad in your trash bin for too long to prevent leaking. That means you should get rid of it as soon as you can.

What you should not do to mop water 

When you no longer wonder what the correct way to handle dirty mop water is, you should also know things you should not do to it as well. Here are four things you need to avoid when dealing with mop water. 

1. Don’t pour mop water into the sink or the bathtub drain:

You already know four places perfect for disposing of mop water, so don’t try to extend that list to answer the question, “Where may mop water be disposed of?”. 

Even when the sink and the bathtub drain seem like good places for dumping mop water just like the drain, these places are easily clogged. Not to mention, these places usually take in more used water than the drain, so it can be overloaded if you pour mop water there too.

2. Don’t leave mop water for a long time:

Mop water contains debris and bacteria, which is harmful to human health. Leaving mop water in the house for too long means these things have the chance to spread. 

Dirty water is also a suitable environment for mold and bacteria to develop. That can create unpleasant smells and allergens in your household. If you can’t find a place to dispose of mop water right after cleaning, at least keep them in sealed plastic bags and throw them out as soon as you can.    

3. Don’t pour mop water into ponds or plants:

Pouring mop water into a pond is not a good idea, no matter if the pond is yours or not. The dirty water will contaminate the pond, creating a perfect home for mosquitoes to lay eggs. It will also kill the healthy ecosystem existing in the pond. 

Pouring mop water onto plants is not recommended either. Since this waste can help you kill bushes and wild weeds, it will also kill your plants even when it doesn’t contain chemical cleaning solutions. 

4. Don’t reuse mop water:

The world has been talking about saving resources lately, and it seems like a good idea to reuse mop water. As we already know, mop water has debris and bacteria in it, so it is not qualified for cleaning anything else.  

The only way you should reuse mop water is to pour it on bushes and wild weeds to kill these unwanted things in your garden. Besides that, you don’t have anything to do with mop water to make it useful again.
