How to Remove Scratches from Aquarium Glass: A Complete Guide

Before you start, make sure to determine how deep the scratch on your aquarium is. This helps decide which repairing technique works best and increases success.

Minor scratches can be repaired quickly, while deeper ones may take longer because of their more significant depth. You can remove scratches from aquarium glass by using the following methods:

Method 1: Removing Scratches from Glass Aquarium Using Cerium Oxide Polish

Cerium oxide can bring out the shine on your jewelry items, but it’s also helpful for getting rid of any scratches that might have been inflicted upon an aquarium. This can be done in the following steps:

  1. To start, you’ll want to remove portions of water from your aquarium so that it’s easier for you. If this scratch lies below, you need to empty all of its content before starting. Ensure there are backups in case anything goes wrong or, worse yet – those fishes getaway.
  2. If you want to keep your live aquarium safe, then it’s best not to let the cerium oxide get into any water. To prevent this from happening, there are plastic wrap sheets that can be used and tape placed over them so they don’t come off.
  3. Apply your favorite buffing pad to an electric drill and secure it using a rubber disk.
  4. Mix water and cerium oxide solution in a spray bottle to be easy for you when applying.
  5. Be sure to spray some of the mixtures on your buffing pad to make it wet and won’t start dripping. You want enough soak but not too much.
  6. For a successful scratch-and-dent removal, you must use the right tools for your aquarium. Use only gentle pressure when buffing with this pad, and make sure to maintain consistent speed so as not to cause any more damage to your aquarium glass.
  7. Keep an eye on your aquarium glass, as it can get very hot. If you notice that the temperature is rising because of friction between surfaces, then spray plain water or a solution of cerium oxide onto them before they cool down, so there’s no permanent damage done.
  8. Once you have buffed out all the scratches, stop immediately and check your progress. If there is still some remaining scratch on top or bottom surfaces, then continue with this step until it’s gone for good.
  9. Wipe the solution with the help of a cloth, then throw it in the wash.

Method 2: Removing Scratches from Glass Aquarium Using Liquid Glass Resin

Repairing and removing disturbing scratches in your aquarium glass is now easier than ever with liquid resin technology. By applying this simple procedure, you can get back crystal clear views of all that lives within it.

  1. The area within the scratch should be cleaned before trying to fix it. You can use cotton swabs dipped in alcohol for this purpose, which will help remove any foreign objects and impurities that could prevent your liquid from setting up properly on top of the existing scratch.
  2. Use a syringe to inject resin into your scratches. Fill it up with liquid and follow instructions for proper injection technique.
  3. Be extremely careful while filling the scratches with resin liquid; you must use a syringe.
  4. Give yourself not less than 24 hours to let this set in.
  5. Lastly, to remove excess liquid, you should buff the area. You can use a similar technique for cerium oxide and apply it here too.

Frequently Asked Questions

Can You Polish Scratch Out of Aquarium Glass?

You can get rid of pesky scratches on your aquarium glass with a bit of help from cerium oxide. This non-water-soluble powder is often used as a part of the process that makes polishing happen, and it is one of the most effective abrasive liquids when removing this type of damage.

How Do You Get Deep Scratches Out of Glass?

Apply some toothpaste to a damp cloth and rub in small circles, making sure you press firmly enough so that the paste leaves an impression of your handiwork on top. Keep going for about 30 seconds before wiping it away with another clean part of fabric or paper towel; if there are still scratches left behind after this point, then repeat as needed.

Does Baking Soda Remove Scratches from Glass?

Mixing baking soda and water produces a soft paste that can be applied to scratches to remove them. Rubbing the mixture onto your finger, you’ll notice how it has an ingrained dirt-removing ability.
Wiping off any residue left behind with clear tap water or even better: lukewarm water will keep this treatment going for as long as needed before repeating if necessary.

Conclusion

So, those are two methods you can use to remove scratches from your aquarium glass. Both work well and will make your tank look new again.

If you’re having trouble deciding which one to try, I recommend the Cerium Oxide Polish method– it seems to be a little more forgiving if you make a mistake than the Liquid Glass Resin.

Whichever method you choose, just be sure to follow the instructions carefully and take your time. Hopefully, this post has enabled you to understand how to remove scratches from aquarium glass.
