Advice From A Professional Window Cleaner

If you are planning on having your windows cleaned by a professional window cleaner  ONLY ONCE this year, or have glass corrosion issues, I highl yrecommend having a glass sealant applied to all exterior surfaces.

Glass sealants provide a layer of protection to exterior glass by creating an invisible barrier between surface and airborne pollutants, hard water, glass oxidization and more. Basically, glass sealants effectively keep window glass cleaner for longer periods of time…

…And, will help prevent problem stains from reappearing after glass restoration procedures.

You may already be familiar with ‘Auto Glass Sealants’

Although auto glass sealants are – not recommended- for use on commercial and residential window glass, professional window glass sealantsare available. And the best part is…

…These sealants are especially designed to be squeegeed off  by a window cleaner. So, they’re an easy, fast and cost effective way to protect your glass from degradation.

Hiring a window cleaner just once this year?… Add a sealant and keep your glass cleaner- longer!

 

Replace or Remove Metal Window Screens

As you learned earlier, oxidization can occur and damage your windows. But, if you already have oxidized glass, it will appear hazy and have a white etched look.

Cause: Metal around exterior window has been exposed to rain or humid conditions causing the metal to slowly deteriorate and become oxidized.

Mostly seen on windows with metal frames or metal screens, this condition penetrates exterior glass surfaces and renders regular window cleaning techniques ineffective.

Again, in most cases the glass can be restored. But, prevention is always the best solution! So, if you have exterior metal window screens, replace them with new screens made of fiberglass. Or, simply remove the screen permanently… It will improve your view!

Do Not Clean Windows With a Garden Hose

Although this technique can remove some of the dirt and grime from your windows, the fact is… This technique can cause more damage to your glass than good.

Why?…

Because your are allowing tap water to dry and remain on your glass. Remember, tap water contains hard minerals that, over time, will degrade the transparent look of your glass.

When using professional window cleaning techniques, tap water use is O.K.  Mixed with soap, the harmful materials in tap water are completely removed from glass with squeegee and not left to dry into the glass surface.

If you are planning to use a garden hose to clean your windows, make sure to rinse the glass completely with pure water. You can effectively create pure water by running it through a reverse osmosis or DI-ionizing resin filtration system. RO and DI systems are available but expensive. These systems also require your household water pressure to fall within a specific range to allow the system to work properly.

The best solution is to hire a professional window cleaner in your area…

Especially if your window c leaning needs require the use of tall ladders or high-access equipment.

Rearrange Sprinkler Systems

Rearrange sprinkler systems so ‘ Tap Water’ does not wet windows. Tap water contains calcium and other hard minerals and will, over time, etch the exterior of the galss.

can this glass be restored to it’s original shine?

99.9% of the time the answer is yes!

Calcium salts from tap water can be removed through the proper use of restoration chemicals, applicators and techniques. Although, once in a great while, I’ve found these techniques and chemicals to be ineffective. In that case, the problem stain has actually changed the molecular structure of the glass, and glass refinishing or replacement may be needed.

So, if your sprinklers are wetting your windows… Rearrange them!

The Importance of Routine Window Cleaning

As mentioned in previous article, window glass can become permanently stained from hard water deposits caused by rainwater and new paint.

But did you know?…

…All of these factors can cause permanent damage to glass:

1. Acid Rain

2. Salt Water Spray

3. Oxidization

4. Over Spray

5.Airborne Pollutants

6. Rust

7. Calcium Salts

Routine Window Cleaning

Window glass is porous. And, if you understand that it’s surface is filled with ‘Peaks and Valleys’, then it’s easy to recognize these valleys easily capture and trap airborne debris that will diminish glass integrity.

To protect your investment…

…We recommend no less than 2 window cleanings per year.

Clean glass also helps the ‘R-Value’ of thermal paned windows. The R-Value is a measure of resistance to heat gain or loss. Regardless of you glass type, a clean window allows the glass to better regulate the affects of exterior weather…

…Which can produce greater effiency and REDUCE your monthly heating and cooling costs!

Painting? … Cover Windows In Plastic

The best answer is always PREVENTION! You can easily prevent the need to remove remove paint from windows by covering, or having your painting contractor cover your interior and exterior glass in plastic.

Paints and stains are corrosive to glass… And, if left long enough on window glass, can cause permanent staining. Also,’Hard Water Stains’ can occur immediately after your building’s exterior is painted or stained. Hard water stains are caused by rain water running over prefabricated surfaces, leaching hard minerals and acids from that surface and depositing them on windows below. In the case of new paint…

…. Damaging stains can occur immediately after the first rainfall.

The need for a complete exterior window clean is a must to prevent glass degradation. The use of proper window cleaning techniques will neutralize the P.H. of the glass and effectively stop the corrosive property of hard water stains caused by new paint.

Just Say “No” to Abrasive Nylon Scrub Pads

Abrasive nylon scrub pads… Like the ones found on the back of many household dishwashing sponges, will scratch window glass. The fact is, window glass is much softer than glass manufactured for beverage containers.

Specialized nylon, fine grade steel wool, and glass scrapers are the professional window cleaner’s choice to safely remove stickers, decals and other hard to remove debris from window glass.

So, if you’re thinking about using that sponge to clean your window…

…Just Say “No” to Abrasive Nylon Pads!
