How to Get Scratches Out of Aquarium Glass

If you have an aquarium in your home, you may be wondering how to get scratches out of the glass. Scratches on the outside can make it difficult for your fish to see and feel safe. Luckily, there are several ways that you can remove these scratches from the exterior of your tank without spending too much money or time.

How to Get Scratches Out of Aquarium Glass

One way is by using the sandpaper method, which will only take a few minutes if done correctly. The sandpaper method requires two pieces of sandpaper, one rough and one fine, along with a water-based lubricant. So, this article is for you. You will learn how to get scratches out of aquarium glass with just one simple trick!

7 Steps to Follow on How to Get Scratches Out of Aquarium Glass

Step One: Locate Scratches

Every scratch in your aquarium glass will need to be assessed, and this step is necessary before moving on to the next one. Look for any minor scratches that may or may not be noticeable by looking into your tank from a different angle to see if you can spot them.

They may seem harmless now, but they may ooze out tiny bacteria in the future, which is very harmful to your fish. As a quick tip, a great way to find scratches you can’t see is by shining a light across the glass from the inside of the aquarium and observing where it goes. Any scratches will show up as a sharp reflection on your glass.

Step Two: Using Sandpaper

Depending on the severity of your scratch, you will be using sandpaper in a different grade range. If you have multiple scratches, it’s best to start with the coarsest sandpaper and work your way down until they’re all removed. If you only have one or two small scratches, then use sandpaper that is medium or fine.

Use Sandpaper to Clean Scratches

However, if you have medium-sized ones, first try using sandpaper on the coarser side of your options. It’s also best to use wet sandpaper, meaning submerge it in water, put enough water into a bowl that the sandpaper will be submerged, and then you want to lightly rub the area where the scratch is using very little force.

Step Three: Using Finesse

At this point, if you have quite a few scratches that are deep-set or they are just too big for sandpaper to do the trick, then another way of getting rid of them is by using finesse. First, you will need to use your fingernail and shape it, so it’s slightly curved. Then lightly drag it across the scratch using very little force to smooth out the scratch.

It’s best to use a slightly damp soft cloth for this process since it will help better shape your fingernail into a curved shape that can successfully get rid of deep-set scratches. Since this is a very delicate process, it’s a great idea to use a nail file for the hard-to-reach spots that sandpaper couldn’t get.

Step Four: Buffing

Now you’re going to want to use a buffing wheel with a polishing compound to ensure that all scratches are gone from your aquarium glass. After you’re done buffing, you can wipe off any powder that comes from the polishing compound, and the glass should look as good as new. This step may take a while, but it will ensure that your tank is scratch-free and ready to go for future use.

Use Buffing Wheel to Polish Glass

Once you’ve successfully removed all scratches from the aquarium glass, make sure to leave no trace behind. The only way to do this is by using a polishing compound that can clean your tank and leave it looking brand new again. This will ensure that you don’t get any scratches in the future, which should be relatively easy since you’ve already done all of the previous steps!

Step Five: Cleaning

After you have successfully buffed your aquarium glass, it’s a good idea to take a towel and wipe down the inside of your tank. This will ensure that you remove any excess polishing compound that may be present. Once all of the powder is gone, you should fill up your tank water to the top and then let it sit for a couple of hours.

This will ensure that your tank is cycled and is ready for fish! You’ve successfully removed scratches from your aquarium glass, and now you can fill it up with your favorite fishy friends or kick back and enjoy a beautiful day to yourself, knowing that the only thing left to do is sit back and relax! This will help in how to get scratches out of aquarium glass.

Step Six: Maintainance

Once you’ve filled up your aquarium, make sure to keep an eye out for any scratches that may appear. Since the inside of your tank is now smooth, it’s much more susceptible to scratches if things are dropped in there or if something sharp gets too close.

To avoid this problem altogether, make sure not to put anything in your tank that can potentially get caught on the glass. You should also avoid touching it with anything that may have sharp edges to prevent any scratches from happening. Since you’ve successfully removed all of the scratches, this should be an easy task!

Maintainance for Your Aquarium Glass

All you need to do to maintain your aquarium is just keep an eye out if anything gets too close to the glass. The rest is up to nature and what fish you decide to put in there! Now that you know how to get scratches out of aquarium glass, ensure that you maintain it properly, so you don’t lose any fish or anything else in your aquarium tank.

Unfortunately, this is not something you can fix easily, so you should probably invest in a new one. Likewise, if you have some intense scratches that are hard to get out of, then it’s probably best to invest in a new tank.

Once you’re happy with your new aquarium, all you need to do is follow the same steps that were given to get rid of scratches from an aquarium! You must clean any old residue on your new tank before putting fish or anything else inside it, so make sure to give the tank a good cleaning first.

How Do You Restore Aquarium Glass?

The glass in an aquarium can be easily scratched, so it’s important to fix the problem if your aquarium is currently sporting a few scratches.  If you fail to get rid of these scratches, they will eventually lead to trouble during the lifetime of your tank.

Fortunately, this process is not too difficult and can be completed using readily available items at your local pet store. However, before you begin, it’s important to remember that you will want to start this process as soon as possible after the scratches have appeared.

If left for too long, you risk staining or clouding your aquarium water due to minerals in the scratch being transferred into the glass and becoming trapped. Since this process also involves removing some of the protective coatings on your aquarium glass, it’s essential not to leave the tank unattended for too long, especially if you plan to put any fish inside.

Does Sand Scratch Aquarium Glass?

A common misconception is that fine sand used for saltwater aquariums can scratch the glass. This comes from the fact that it feels similar to running your finger down a piece of paper, where you feel the friction between your finger and the grain of the paper.

While this may seem true at first, it doesn’t make sense because you are only sanding down one side of the glass. While sandpaper reduces the surface area of a piece of wood by piling up paper fibers, you would theoretically need to sand both sides of aquarium glass for it to be fully sanded.

This would not be practical because you would end up sanding the aquarium once a month and almost certainly making it worse rather than better since you would have to sand out scratches and re-polish the glass each time.
