Eight Tips for Cleaning Car Windows Without Streaks

While cleaning your car windows isn’t exactly the most glamourous part of detailing, it is certainly one of the most important when the rest of your vehicle is shining. To help rid yourself of those unsightly streaks, we’ve put together a list of tips to get your glass sparkling for the upcoming summer season.

1. Clean out of direct sunlight. 

Ever see those little white streaks after you’re done cleaning? That’s probably the cleaning agents from your window cleaning formula which have dried on the surface. Be sure to clean on an overcast day or in the shade. Otherwise, if you clean in direct sunlight, your car windows will be too hot and the formula will evaporate on the surface before you have a chance to wipe clean.

2. Use a low pile microfiber towel. 

Outside of the actual window cleaning product, your selection of a high-quality microfiber towel is perhaps the most important factor in streak-free window cleaning. You’ll want to use a low-pile tight weave microfiber cloth. The tight weave on these towels provide a little extra scrubbing ability which is excellent for glass surfaces.

3. Clean the interior windshield from the passenger seat. 

For easier access to the windshield, sit in the passenger seat. You’ll avoid having to contend with the steering wheel which will ensure that all areas are cleaned.

4. Use the back of your hand for cleaning the windshield. 

To give yourself a bit more leverage and cleaning power, put the microfiber on the back of your hand and press against the glass. This will also allow you to reach those top and bottom corners more easily.

5. For interior windows, spray on the towel first. 

When cleaning interior windows (especially the windshield) be sure to spray your microfiber towel first. This will help avoid overspray onto previously cleaned areas, and keep the cleaner off the dashboard.

6. Roll down your windows. 

To reach the top sections of glass, be sure to roll down your windows about halfway. This will allow easier access and ensure all sections are cleaned.

7. Work methodically and don’t rush the process.

Many people mistakenly believe they can simply spritz down the glass and quickly buff clean. Unfortunately you will end up rushing the process and most likely end up with poor streaky results. Taking your time to slowly and methodically clean each window will pay dividends at the end of your cleaning process.

8. Use the right product. 

Select a product designed specifically for cleaning automotive glass. Traditional household cleaners can contain ammonia which will damage any coatings or tint on the glass. Eco Touch makes a solvent-free glass cleaner which is safe for cleaning all automotive windows.

The Basics of Performing a Waterless Car Wash

Let’s start by being clear about something – using a waterless wash product is not hard. I know, it can sound intimidating at the start. Where’s the hose? Where are the suds? But trust me, after cleaning just a few panels you’ll be hooked on the process. The speed at which you are able to simultaneously clean and protect your car in one simple step is quite amazing. To help anyone just getting into this method of washing, we’ve assembled a list of best practices.

1. Work from the top of the car down. 

Car’s naturally accumulate dirt along the lower body panels and you’ll want to tackle these areas last. Start with the roof->hood->door panels->trunk->lower body panels. Be sure to pay extra attention near wheel wells where heavy debris t.

2. Use quality microfiber towels. 

Outside of the waterless product you use, make sure you have a good stock of high quality microfiber towels. We suggest towels with a 300 GSM rating, as they offer the best combination of cleaning and polishing. While many people think that using a higher GSM towel is better, it can surprisingly work against you. We’ve found that those fluffy 400+ GSM  towels do not clean as effectively as their lower 300 GSM counterparts.

3. Fold your towel in half and half again.

You’ll want to maximize the number of sides on your towel. By folding in half twice, you’ll effectively get eight sides to work with. Use at least one side per panel depending on how dirty the vehicle is.


4. Work in small sections. 

Start with a 2ft x 2ft area for applying and buffing off the waterless formula. If your car is completely cool and relatively clean you may be able to work in larger sections.


5. Wipe in one direction. 

Follow the contours of the car’s body and wipe in the direction of normal airflow over the panel. This will help prevent re-soiling the areas of the car you’ve already cleaned. You should not use a circular buffing motion as if you were using a wax.


6. Apply light pressure on first stroke to remove contaminants. 

You’ll want to apply light pressure on your first pass over the panel. We suggest using the wipe and ‘lift’ technique where you are simultaneously rotating the towel while wiping across the surface.


7. Keep your buffing towel separate, clean and dry.

Pick one set of towels for the cleaning and one for buffing. For best results you want to have your buffing towels near 100% dry. Many times we’ve seen detailers use two towel colors so it’s easy to remember which is which.
