How to Clean Aquarium Glass With Vinegar

6 Steps to Follow on How to Clean Aquarium Glass With Vinegar

Step One: Determine

First, remove any large pieces of debris from the inside of your glass tanks, including fish food. This will help you avoid scratching the glass when using the razor blade. You may also use water to clean off any remaining dust that might be on your tank before moving on to the next step.

If you have a large aquarium, say 100 gallons or more, it would be wise to set up a bucket under the tank and remove as much water as possible before vacuuming. This will help you avoid any moisture from the hose getting on your glass.

Also, if you do not remove enough water and then vacuum with force pressing against the bottom of the tank, you could end up cracking or breaking your glass. If you remove all the water, please be sure to put it back before placing your fish in again.

Step Two: Prepare

First, you will need to get a razor blade and some paper towels. Next, you will want to wet the tank with water and clean off any remaining debris on it. You can then slide the razor blade down the inside of your glass to eliminate any large pieces of debris still sticking to it.

Be sure that your tank is completely dry before continuing to the next step. If you do not, then the vinegar will mix with the water and cause a smoky liquid all over your glass. You can avoid this by making sure that your tank is completely dry before you proceed.

Tank Is Completely Dry

If you have a saltwater tank, be sure to rinse it with fresh water before you move on. If not, the vinegar may react badly inside your tank and begin to destroy your biological filters and water heaters. This will help in how to clean aquarium glass with vinegar.

Step Three: Get Your Vinegar Ready

Use an eyedropper or pour some vinegar onto a paper towel and clean off any remaining debris left on the glass. If you use an eyedropper, please be sure not to get any of the vinegar inside your tank as it may harm your fish and corals. However, if you spill some into your tank, not all is lost if done in small amounts.

However, if your glass was already wet and you spill a large amount of vinegar all over the inside of your tank, it may cause a cloudy effect on your glass which will not go away. If this occurs, you can manually clean the inside of your tank with a razor blade while the water is being changed one time per week for about three weeks or more to remove any cloudiness that the vinegar may have caused.

It is also wise to avoid using vinegar if you have any plastic plants in your tank. Over time, vinegar can cause the plastic to deteriorate. If you do use vinegar with these items in your aquarium, please be sure to change them out every few weeks or so during water changes so they will last longer.

Step Four: Cleaning Up

When you’re done cleaning, please be sure to rinse off your glass with water and allow all of the water to drain before placing your fish back into your tank. If you do not clean your aquarium thoroughly after using vinegar or scraping debris from it, then there is a high chance that some may get caught inside of your filter and cause problems down the road.

Clean Your Aquarium

Also, never use soap when cleaning your aquarium glass. This is because it may cause an allergy to your fish or even kill them if too much of it gets into their water. If you used vinegar in your aquarium and can not get rid of some cloudy residue in the bottom, please see my article on removing cloudy residue from your aquarium.

Now that you know how to clean your aquarium glass with vinegar, please do so every few weeks or so to maintain its cleanliness. You can also decide to use distilled water instead of tap water if you are using vinegar. These steps should help you in learning how to clean aquarium glass with vinegar.

Step Five: Maintain the Cleanliness

Continue to clean your glass every few weeks or so to keep it free of debris and smudges. This will also help you avoid getting scratches on the inside of your tank when cleaning it down with vinegar each time that you do. If you find that this is becoming too much for you, purchase an aquarium with a glass top.

Step Six: Enjoy Your Clean Glass

When you’re done cleaning your glass, not only will it look shiny and new, but the fish in your tank will enjoy you for it too. This is because they won’t have to stare at that one stubborn green spot on your glass any longer! So go ahead, get out that vinegar of yours and give your aquarium a good cleaning.

Look Shiny and New

If you happen to use vinegar on your glass, please choose distilled water over tap water next time you are at the store to purchase some. This is because vinegar can leave behind a lot of residues that may irritate your fish or even kill them if too much gets into their aquarium.

It is also a good idea to avoid using vinegar with any plastic plants in your tank. Over time, vinegar can cause the plastic to deteriorate, and it is best not to take that chance when cleaning your glass with it.

Is Vinegar Harmful to Fish?

It is a common misconception that vinegar, which is an acid, is harmful to fish. Most acids are not only harmless but also beneficial for the health of your aquarium’s inhabitants! If you have a planted tank with live plants in it, you should be using Aquarium Plant Food a few times a month.

This helps ensure that the plants make as much food as possible, which is necessary because fish excrete waste that contributes to algae blooms. This is the only time you should avoid acids in your aquarium! You don’t want to use vinegar or any other acid on plants actively growing because it will stunt their growth.

For this reason you shouldn’t use acids on newly acquired plants, as they need time to grow their roots, or at least you should quarantine them first before putting them into your aquarium for a few weeks. But, of course, if you keep your fish in an aquarium without live plants, then there is nothing to worry about!

Frequently Asked Questions

What Do You Clean Fish Tank Glass With?

If you’re looking for an all-purpose cleaner that can be used on a variety of surfaces, then you may want to consider using white vinegar. White vinegar is heavily diluted with water, so it’s safe to use around fish and other aquatic creatures. It also has antibacterial properties, which help to keep your tank clean and healthy. Additionally, white vinegar can work as a degreaser on metal surfaces and remove dust and dirt from cracks and crevices in tiles or roofs.

Can You Use Vinegar to Clean a Fish Tank?

Yes, vinegar can be used to clean a fish tank. Vinegar is a natural disinfectant and will kill any harmful bacteria or fungus that may be present in the tank. Just make sure to rinse the tank and all the equipment thoroughly after using vinegar to clean it, to avoid any negative effects on the fish.

What Does Vinegar Do to Fish?

Vinegar does more than just add a sour taste to your food. In fact, vinegar can do a lot of things for fish that you may not have realized! For example, vinegar helps to clean and freshen the fish by breaking down its skin and removing excess oil. It also inhibits the growth of bacteria and fungus, which is essential for keeping seafood safe to eat.

In addition, vinegar has anti-inflammatory properties that can help reduce inflammation in the mouth or gastrointestinal tract.

How Much Vinegar Should I Put in My Fish Tank?

If you are new to fishkeeping, then it is important to be aware of the different types of fish and their dietary requirements. Some freshwater fish, like cichlids and guppies, require relatively low levels of water chemistry (pH), while saltwater fish like sharks and rays need a more acidic environment.

When adjusting your aquarium’s water chemistry, make sure to maintain a pH level between 6-7.5 at all times in order to accommodate both types of fish. To do this, add vinegar (3% solution) every few weeks or as needed until the pH reaches the desired level. Be sure not to overdo it since too much vinegar can change the acidity levels too far down in the aquarium’s ecosystem, which could harm your fish!


Vinegar is a solid natural cleaner that can be used to clean aquarium glass. The vinegar will create an acidic environment that kills algae and other bacteria on the surface of the water, as well as any dirt or grime that has accumulated in your tank over time.

Cleaning with vinegar also helps prevent new debris from sticking to the inside of your tank because it creates such a slippery coating on the glass. We recommend using white distilled vinegar for best results, but apple cider vinegar may work for light cleaning jobs if you don’t have access to anything else! 

It is also recommended that you use distilled water instead of tap water with vinegar because it will leave behind a lot of residues. The conclusion paragraph is informative and provides information on how to clean aquarium glass with vinegar.
