No Scents

No Scents

Invisible Glass is free of added fragrances that can become household irritants and streak glass, unlike other brands which contain synthetic fragrances, harsh fumes, and ammonia.

No Dyes

No Dyes

Our Clear Dry® formula is free of added dyes and colors. Dyes and colors are great for making a product stand out on the shelf, but they cause streaking and surface staining. That’s why we keep Invisible Glass as clear sparkling clean glass.

No Residues

No Residues

What good is a glass cleaner if it leaves behind residue? Residues from soaps, scents, dyes, and additives are found in many glass cleaners. These residues cling to glass surfaces forming streaks and attracting dust and grime. Our Clear Dry Formula is specially designed to completely evaporate, leaving nothing behind but beautiful glass.

No Streaks

No Streaks

Invisible Glass contains water-soluble cleaners that work better breaking down greasy fingerprints, pet slobber, dust, and grime, leaving your surfaces streak-free.

Clean Bird Droppings Off Your Windshield the Easy Way


Many how-to articles claim the only way to remove bird droppings is with lengthy soaking, but we’re here to share a faster method. Keep reading if you want to learn how to quickly clean bird droppings off of your windshield!

The secret is simple: use a professional glass stripper instead of traditional car washing techniques like soap and water. You can remove dried bird droppings in minutes, all without damaging your glass. Just follow these simple steps:

  1. Briefly clean your windshield with a regular glass cleaner
  2. Strip bird droppings away with glass stripper
  3. Rinse your windshield
  4. Buff with a clean cloth
  5. Apply rain repellent

That covers the basics, but there’s a lot more to it. It doesn’t take long to clean bird droppings off of your windshield, but using the right technique makes a difference.

Clean Your Windshield to Remove Everyday Grime

Start by cleaning your windows to eliminate any particulate on the surface of the glass. It could be dust, salt (if you’re in the Northeast), or just general grime. Cleaning this off lets the glass stripper focus its cleaning action on the most difficult contaminants, like dried bird droppings and other hardened gunk.

Cleaning your windshield before you strip it makes the whole process more effective. You should us a glass cleaner without additives—something without added soaps, scents or dyes. Using a pure glass cleaner ensures you’re not leaving sticky residue on your glass when the cleaning solution dries.

Strip Bird Droppings Away With Commercial Glass Stripper

Now it’s time to break out the good stuff— a commercial glass stripper! Some glass strippers come with an applicator sponge, while others recommend using a clean cloth. The process is similar for all of them, so we’ll describe using one with an included applicator sponge. Apply the glass stripper to the more porous side of the applicator sponge (the foam with larger holes), then gently scrub it onto your glass with small circular motions. Focus on the areas with bird droppings if you’re in a real hurry, but it should only take an extra minute or two if you want to strip the whole windshield.

Re-apply the glass stripper to the sponge as you go; the area of the windshield you’re cleaning should be covered by a thin layer of product by the time you’re done, and the bird droppings should come away completely. Apply as much glass stripper as necessary until the droppings are completely cleaned away.

You should press with moderate firmness as you apply glass stripper to your windshield—use enough pressure that the applicator sponge compresses slightly, but not so much pressure that you can feel the glass through the sponge with your hand. If you’re using a cloth, layer it several times so that there is plenty of fabric between your hand and the windshield. Commercial glass stripper products are formulated to remove bird droppings and other contaminants without damaging your glass, so it doesn’t require excessive elbow grease or heavy scrubbing.

Rinse Windshield With Clean Water

Once you’ve cleaned the bird droppings and other gunk off of your glass, simply rinse the Glass Stripper from your windshield with water. Make sure that you rinse all the bird droppings off and don’t let any leftover rinsing water dry on your paint. Bird droppings are an ugly mess on glass, but they can actually damage paint if left to dry.

Some of the glass stripper will likely stay on the glass as you rinse, and that’s ok. Rinsing is only meant to remove contaminants and any excess glass stripper that hasn’t dried so that the next step can be completely more quickly.

Dry With a Clean Microfiber Cloth

Use a clean microfiber cloth to remove the last of the glass stripper, wiping in side-to-side motions. It’s better not to use newspaper, rags, and paper towel for this step. They aren’t made for cleaning, and can leech inks, dyes, glues, and other unwanted substances onto your freshly-cleaned glass, which is counterproductive. 

Lint is also a problem, especially with paper towel and cotton rags. A good microfiber cloth is designed for lint-free cleaning, and won’t have any dyes or inks to spoil your carefully-stripped windshield. Using the right tool will save you a lot of time and frustration.

Protect Your Windshield With Rain Repellent

In some ways, this final step is the most important: adding a hydrophobic coating. Stripped glass is completely bare—this is great for visibility, but bare glass doesn’t shed water very well. It’s important that you stay safe by adding a water-repellent coating to the glass.

Water repellent coatings dramatically improve your visibility in wet weather. They make your windshield more “slippery,” causing water the roll right off instead of gathering in sheets or pooling. Rain repellent will also protect your windshield by making it harder for bird droppings and other contaminants to stick to the surface.

Be sure to use a professional rain repellent for this step. It might be tempting to rely on a windshield washer fluid that comes with rain repellent already mixed in. That approach is best considered as maintenance for your existing hydrophobic coating, especially when you’ve just stripped your glass down to a factory finish.

Instead, thoroughly apply a fresh coat of rain repellent to your entire windshield, then let it dry or buff it with a clean cloth, as directions indicate. This creates a protective layer between your windshield and wet weather—whether it’s rain, snow, road spray, or anything else.

Why are bird droppings hard to clean?

What makes bird droppings such a pain to clean? There’s an organic acid—uric acid—in bird droppings that makes them cling stubbornly to any surface they land on. Uric acid isn’t water-soluble, so standard car wash techniques tend to underperform. Most people find that a normal car wash only partially removes bird droppings.

Uric acid also makes bird droppings harden very quickly in the sun. The warmer the temperature, the less time you have to remove the droppings before they become rock solid.

Aside from being insoluble and fast-drying, uric acid’s highly acidic chemical makeup can eat into auto paint. Droppings cause permanent damage to paintwork (in the form of “etching” marks where the clear coat is melted away) if left to dry, so make sure that the water you rinse your windshield with doesn’t end up sitting on the body of your vehicle after you clean.

These three undesirable qualities make bird droppings a unique threat to your vehicle’s appearance and value. Cleaning them as quickly as possible is the only way to eliminate potential long-term problems.

What Else Can Glass Stripper Products Remove from Windshields?

Bird droppings aren’t the only pesky contaminant that can end up on your windshield. Dead bugs, hard water spots, and tree sap are top offenders when it comes to difficult substances to remove from glass. There are various methods to deal with each, but using a glass stripper is almost always the fastest. If you don’t have the hours to explore DIY options or leave your car to soak, a glass stripper can save you precious time when dealing with any of the following:

Dead Bugs

Dead bugs are similar to bird droppings—they also contain organic compounds that make them harden and stick to your glass. They’re not heavily acidic like droppings, but still dry rock hard when they sit in the sun. If you have to deal with a lot of dead bugs, a glass stripper can make quick work of cleaning them up.

Hard Water Spots

Hard water—water with high mineral content—is a common problem across the US. The minerals get left behind as white spots or patterns when hard water dries, and they are notoriously difficult to clean. Glass strippers work to remove the mineral buildup without requiring undue force. This keeps your glass clean and doesn’t put it at risk for scratching the way that other cleaning methods might.

Tree Sap

Tree sap is another widespread source of windshield gunk. Everyone knows where it comes from, but sometimes it can’t be avoided. Whether you park your car under trees out of necessity or just to benefit from some shade, glass stripper can help you get rid of any sap that ends up on your windshield.

The Quickest Way to Clear Away Bird Droppings

Your car is a valuable possession. It’s a source of freedom, a reflection of your personality, and, if you use your car for work, a source of income too. That makes it all the more frustrating when birds mess all over your windshield.

Follow these simple steps to clean bird droppings away as quickly as possible:

  1. Clean your windshield to remove everyday grime
  2. Strip bird droppings away with commercial glass stripper
  3. Rinse windshield with clean water
  4. Dry with a clean microfiber cloth
  5. Protect your windshield with rain repellent

Speed is the most important factor when cleaning bird droppings. The faster you can get rid of them, the less they can dry and solidify, and the easier it will be to remove them.

Even if they are rock hard, using a glass stripper is the quickest way to get them off of your glass. Don’t let them sit a minute longer then they already have…clean them right away!
