Owning a projector is great, but scratches on the lens can be a pain. They can be very distracting, resulting in a less than optimal viewing experience on your projector screen. In fact, you might even think you need to buy a new projector.
But did you know that you can fix your own scratched projector lens at home? Yes, you don’t need to replace your entire projector because the lens has scratches. Nor do you have to call in a professional to fix it.
In this guide, you’ll learn how to remove scratches from your DLP LCD projector lens and what causes scratches in the first place.
Can scratches be removed from the lens?
Can you get the scratches off yourself?
The answer to that question depends on the type of damage. If the scratch just affects the surface of the lens, then you might be able to remove it. However, if the scratch goes through the entire lens, then your best bet is going to be to replace the lens.
How to remove scratches from projector lens
Before we delve deeper into how to remove scratches from projector lenses, let’s look at what causes scratches in the first place.
The scratches may be a result of dust, or they may come from the cleaning process.
If the projector is on while you’re cleaning it, dust can fly up and scratch the lens. Also, if the cleaning cloth isn’t lint-free, it can leave dust on the lens, which will eventually scratch it. Moreover, if you clean too hard or use something abrasive like sandpaper or steel wool, you’ll scratch the lens with that.
Fortunately, there are ways to remove most scratches from projector lenses. While some methods are ineffective, others work well for many people.
A popular remedy is to use baking soda or toothpaste (not gel!) to rub out the scratches gently. You can also try glass polishing or a projector lens scratch repair kit.
Note: Before attempting any of these methods, ensure the problem isn’t lens fungus. Yes, you can easily confuse fungus buildup for scratches as it causes fuzziness and dulling of the picture quality. However, it typically doesn’t affect the glass or other materials in the lens.
Method 1: Using toothpaste
Step 1: Use a microfiber cloth to remove any dust or dirt from the projector lens. Then give it a once-over with the cloth dampened with water. Be sure not to let any moisture seep into the lens. But if you do, dry it thoroughly with the microfiber cloth.
Step 2: Squeeze a pea-sized dab of toothpaste onto a clean microfiber cloth. Wipe it on the scratched area of your projector lens in a circular motion.
If you have deep scratches, use a little more toothpaste than usual. But don’t use it so much that it starts to get sticky.
Note: Make sure you’re using non-gel toothpaste for this method. The abrasive particles in regular toothpaste will help remove scratches from your lens without damaging the plastic of the device itself.
Step 3: Use another clean portion of the same microfiber cloth to wipe away any excess toothpaste residue from your projector lens.
Method 2: Using baking soda
Step 1: Mix equal parts of water and baking soda in a bowl. Then mix until it forms a thick paste.
Step 2: Dip a cotton swab into the paste and apply the paste to the scratch on the projector lens. If any scratches are still visible, apply more of the paste and repeat until they have disappeared.
Step 3: Wipe away the excess paste. You don’t want any to remain on the lens after you’re done.
Note: If your projector lenses are still scratched after this treatment, use your lens polisher to gently buff out any remaining scratches on each of your lens surfaces.
Method 3: Using scratch repair kit
If neither of these methods works well enough for what needs fixing, then try scratch removal kits. They’re available at most hardware stores and come with instructions on how to fix minor damages.
How do you polish a projector lens?
Do you want to remove scratches from projectors with glass lenses? If so, this method is excellent, especially for epson projector lens cleaning.
Step 1: Look for a glass-polishing compound. You can purchase a polishing compound at an automotive store or online. Most polishing compounds contain cerium oxide, an abrasive that removes scratches from your projector lens.
Step 2: Apply the polishing compound to a clean piece of microfiber cloth or cotton cloth. The cloth helps to spread the compound evenly over the lens and reduce its abrasiveness. It’s best to use a clean piece of cloth, so you don’t accidentally scratch the lens with dirt particles.
Step 3: Rub the cloth in small circular motions around the scratch on the lens until it is gone. The more you rub, the more abrasive your polishing compound will become.
Note: Be careful not to scratch the lens. Applying too much pressure can actually increase any damage to your lens and make it worse.
Step 4: Rinse off any polish residue with warm water and dry it off with a clean towel before using your projector again.
How does baking soda remove scratches from glasses?
Baking soda works to remove scratches from glasses by being an abrasive that can fit into the small cracks caused by scratches.

Why does toothpaste remove scratches?
Toothpaste contains abrasives like silica, which helps remove stains and dirt from the surface of your teeth. The reason it works so well at removing scratches is that it has a high concentration of these abrasives.
Scratches on glass are more like tiny grooves on the surface. Toothpaste can fill those grooves by smoothing them out, thereby removing the scratches.
Note: Toothpaste may not always be effective at removing scratches, though. It depends on how deep the scratch is and what type of glass was used to make your lens.
If you have plastic lenses, it’s likely that they will be easier to buff out with toothpaste than if you have glass lenses. Also, if your glasses have just one or two minor scratches, toothpaste is more likely to work than if there are lots of deep scratches.
Does WD 40 remove scratches from glass?
WD 40 is a great household product to keep around for its many uses. In fact, it can remove all kinds of stains and dust from glass.
