Glass Cleaning Tips and Tricks

Cleaning car windows is one of the areas of cleaning a car that can be really frustrating at times, especially as it’s usually the last thing to do. What you think is a 5 minute job can often take much longer when trying to get that streak free glass we all want.

Here are some glass cleaning tips and tricks to get you some great results when cleaning your glass.


To start with I’m quickly going to go over some of the glass cleaning products, tools and cloths that you will need in order to achieve crystal clear glass. Feel free to skip this part for now however be sure to refer back if necessary.

Glass Cleaning Tools

— Glass Cleaning Products 

Meguiar’s Glass Cleaner Concentrate – This is my current choice of glass cleaner, I buy it in bulk and dilute it with distilled water (can also use tap water). It works out very cost effective, smells great, and doesn’t strip any glass sealants or coatings I have protecting my glass. It’s also a safe glass cleaner for tinted windows.

Isopropyl Alcohol –  Isopropyl Alcohol (IPA) is what I typically like to use on interior glass, It’s very effective at cutting through grease and grime and evaporates very quickly, this reduces the chance of streaks and smears being left behind. I dilute this 50:50 with distilled water (or tap water).

Razor Blade Scraper – This is a great tool for removing stuck on bugs, tree sap and general contaminants that get stuck to your glass. 

Magic Eraser Sponges – This is a great tool for cutting through grease and grime on interior glass.

— Glass Cleaning Cloths 

 Microfibre Cloths (Blue) – My go to cloth is the microfiber cloth, I use the same cloths for most car cleaning jobs, however I specifically use the blue ones only on glass. My reasons for doing this is so that they don’t accidentally get contaminated with dirt, grease, grime or any other detailing products like wax etc.. This could potentially leave streaks and smears that would would be a pain to remove.

 Microfibre Waffle Cloths – Another type of microfiber cloth I like to use, this is a low pile cloth that is very good at absorbing water, this is useful when trying to soak up any remaining glass cleaner in order to leave the glass streak free. 

Blue Paper Roll – This is just blue paper roll, kind of like newspaper. It is not completely necessary however sometimes glass can be very grabby which often pulls the fibres from your cloths leaving it all over your glass and generally making it hard to buff clean.


— How To Clean Glass 

Exterior Glass Cleaning

I personally find exterior glass much easier to clean. The main reason for this is probably due to having much better access to the glass, as well as not having to worry about accidentally spraying sensitive areas of the vehicle with glass cleaner like on the inside of the car.

Glass Cleaning Wash Mitt

To start with, I simply wash the glass as I normally would when cleaning my car. For me this involves a lathered up wash mitt and soap and water. Doing this knocks of most of the loose dirt and debris giving you a much cleaner surface to work on. The last thing you want to do is to be smearing dirt and dust around when trying to achieve a streak free finish.

If you don’t want to break out the hose and wash buckets, simply saturate the glass and a microfiber cloth (one that you’re not worried about getting too dirty) with glass cleaner, and mop up the dirt from the glass.

Glass Cleaning Razor Blade

If the glass has stuck on bugs, tree sap or other contaminants then now is time to use the “razor blade scraper”, make sure the blade is clean and not rusty before use. Use some kind of liquid (water or glass cleaner) to lubricate the glass, then gently glide the blade over the glass at a 45 degree angle in order to scrape off the contaminants. Make sure the glass is well lubricated as this helps the razor blade to glide smoothly, as well as suspend the unwanted contaminants. Wipe the contaminants and liquid away with a microfiber cloth when done.

After you’re satisfied that your glass is free from dirt and bugs etc.. now is the time to finish the glass.

Get 3 microfiber cloths (2 regular blue and 1 waffle cloth if possible)

  1. Saturate the glass and a microfiber cloth (regular blue)  with glass cleaner, then scrub the glass making sure to get into all the corners. This will ensure the glass is free from any remaining dirt.
  2. Take a second clean microfiber (waffle cloth) and mist 2-3 times with glass cleaner. Buff the glass thoroughly with the cloth, making sure to once again get into the corners. You are aiming to get the glass looking as clear as possible at this stage. 
  3. Take your third clean, dry microfiber cloth (regular blue), and lightly buff the glass to ensure any very fine streaks or residue that you may or may not have noticed are removed.

Streak Free Glass

Continue this process around the rest of the exterior glass. Rotate your microfiber cloths to a clean side regularly to ensure the cloth remains clean. You may need to swap out your cloths if they get too wet, otherwise you may have streaking issues.

A couple of tips you may want to do are to lower the windows in order to access the very top of the glass when cleaning. Also give the windscreen wipers a wipe with glass cleaner in order to clean them, keep in mind that this will leave a dark black dirty streak on your cloth so don’t use anything fancy to do this.

Interior Glass Cleaning

Cleaning interior glass is in my opinion a lot more effort to get right, this is mainly due to it being awkward to access as the steering wheel, dash board and centre console get in your way. However, you also have to manage your cleaner as you don’t want it spraying over the dash board and other parts of your cars interior. As glass cleaners tend to evaporate very quickly, you may not be able to wipe away the overspray quick enough, as it dries it could potentially stain the dashboard.

For this reason, when working on interior glass, you want to spray cleaner only on your cloths and not the glass itself (mainly the front windscreen).

For interior glass I like to use a diluted Isopropyl alcohol mix, this is because Isopropyl Alcohol is a very good degreaser.  Interior glass can often accumulate a greasy film, as well as fingerprint smudges and other oily contamination that if not cleaned away will simply be smeared around the glass.

Interior Glass Cleaning

For the front windscreen sit in the passengers side seat to allow for better access to the glass, this will allow you to reach behind the steering wheel much easier. The cleaning process is pretty much the same as the exterior, so once again take 3 clean microfiber cloths (2 regular blue and 1 waffle cloth if possible).

  1.  Saturate your first (regular blue) cloth with the IPA mix and begin scrubbing the glass, if very greasy you may want to flip the cloth to a fresh side and repeat the cleaning process a few times in order to remove all of the greasy film. You can also scrub the glass with a magic eraser sponge and the IPA mix as an alternate way to cut through the grease, wipe the dirty residue away with your first microfiber cloth once done.
  2. Take a second clean microfiber (waffle cloth) and mist 2-3 times with glass cleaner. Buff the glass thoroughly with the cloth, making sure to once again get into the corners. You are aiming to get the glass looking as clear as possible at this stage. 
  3. Take your third clean, dry microfiber cloth (regular blue), and lightly buff the glass to ensure any very fine streaks or residue that you may or may not have noticed are removed. At this stage when you go to buff the glass with a dry microfiber, the glass can sometimes be very grabby. This can make it awkward to buff and can also pull  the fibres out of the cloth leaving them all over the glass. If this happens, simply grab some of your blue paper roll instead of the microfiber, I find that in this particular situation, the blue roll tends to be easier to use and doesn’t leave any fibres behind.

Once again, continue this process around the rest of the interior glass. Rotate your microfiber cloths to a clean side regularly to ensure the cloth remains clean. 

And that’s it! Quite a lot of information but it’s not to complicated once you understand the process. The most important part of cleaning glass is to ensure that the cloths you’re using are clean, so get some microfiber cloths dedicated for use on glass only. Also be mindful about how you wash them. As an example you don’t want to go washing them with dirty microfiber cloths that have been used for wax removal or tar removal, as this could accidentally contaminate your glass cloths, meaning when you next go to use them on glass, you could potentially be introducing streaks and smears due to the residue left over by other detailing products that you’ve used.
