Service: Regular Cleaning of Fabric Window Coverings

Service: Regular Cleaning of Fabric Window Coverings 

PRESIDENTIAL PLACE (BOCA RATON) – Pictured, is a waiting area off the kitchen of an upscale condominium belonging to a long-time, loyal customer. She’s had me schedule regular cleaning of fabric window coverings throughout her home for nearly 10 years now.

Her Hunter Douglas Silhouettes, especially, are prone to the unsightly collection of dead insects inside their vanes (fabric louvers). One or two tiny ones here and there are not necessarily that noticeable. However, the buildup increases over a two or three year period and I inevitably receive the call.

Some homeowners request regular cleaning due to concerns over allergens trapped in their window fabrics. Others are simply obsessive about cleanliness.

I’ve even made repeated visits to a private home whose Muslim prayer room contains an eternal flame. It’s an oil lamp that continually throws off small amounts of black soot, which over time builds up on the home’s snow white Silhouettes. In as little as 6 months they begin to appear dingy. After a year, downright grimy! My ability to reverse the condition (below) keeps me in good standing.

Notes & References

 Silhouette’s manufacturer recommends a thorough cleaning every 3-5 years, to prolong life expectancy. This is a good rule of thumb for any fabric window covering.

Though not always visible to the naked eye, pollutants in the air are ever present. Some possess the ability to break down fabrics. Check out this TIME magazine feature to learn about some of the components the dust in your home may contain.

Requested Service: Hunter Douglas Silhouettes Cleaned

LOBLOLLY PINES – For aesthetics and functionality this homeowner could not have selected a better window covering for her master bedroom window openings. Elegant look with light filtering properties even as it provides visibility, during the day. Then, with a flip of the vanes, that all important privacy at night. 

One drawback is that insects have a tendency to crawl between the fabric layers and die there. (TIP: Use canned air to blast those critters out.) In this case there had also been a roof leak, causing water stains hither and thither.

Having been thoroughly satisfied with our work on previous projects, the property manager reached out. We’re so thankful for such continued confidence in our abilities.

Enemy Sun

The Toll it Takes

Most of us are aware that the sun’s powerful rays can damage unprotected skin. We know its intense heat often transforms metal objects into firebrands. Less discussed, is its effect on fabrics.

Shown in the featured photo is a Silhouette® shading by Hunter Douglas, whose rear fabric layer has been ravaged by years of exposure. The shade was one of three, covering a guest bedroom window (inset).

Interestingly, the three were in varying stages of deterioration, with the one pictured suffering the worst of it. A small area of its bottom vane showed a mottled, slightly out of alignment appearance when viewed from the front. Otherwise, all three looked just fine at first glance. In fact, the owner had initially summoned us to clean them. She had no idea what bad shape they were in.

The Bearing Location Has

At this point a little background on the residence may be in order. An eighteenth floor penthouse condominium, situated on the Southeast corner of the building, it’s Eastern exposure receives as little as two hours of morning sunshine, daily, thanks to a large patio overhang. The Southern exposure gets almost no direct sun during the summer months. However, with no overhang, in winter the sun is on it all day looooooong. Welcome to the side of the building occupied by our opening with the wrecked shades.

Now, the openings facing East were also fitted with Hunter Douglas Silhouette® shadings. But they did not show anything approaching the same extreme damage. Likely, owing to two factors. They were newer by two years, and they never saw the sun at its most intense, for prolonged periods.

SIDE NOTE: Given that this level of damage to window treatments is seen much more frequently in high-rise settings than at ground level, one is left to wonder what part elevation, however marginal, may play in intensifying the sun’s damaging rays.

As it is primarily a winter home, the residence is occupied only about 150 days a year. It’s understandable, then, that the progression of damage escaped the homeowner’s notice. Especially when you consider the fact that a dilapidated barn, for example, may appear to be structurally sound for years before deterioration accelerates as it nears the day when, inevitably, it falls down.

Plotting a Solution

Also understandable, the homeowner’s dismay at what a short life her now useless window shades had enjoyed. As well as her reluctance to replace them with the same type of product. But, what to go with, instead?

Manufacturers make no representation as to which of their fabric products fare better under extreme conditions. And perhaps wisely so, for there are many factors that can hasten sun damage. These include, but are not limited to, heat, humidity, dust, convection, and even the type of glass damaging rays pass through before actual contact with the fabric. The unofficial position is that, since there are so many possible combinations, and that they differ from opening to opening, such factors simply cannot be quantified.

That said, consensus seems to have it that non-woven fabrics, such as those used in honeycomb shades, have a greater life expectancy than woven fabrics, like those found in Silhouette®. However, they all utilize glue lines to hold their respective cells, louvers and vanes together and these are also known to break down with long term exposure to sunlight. In the final analysis, it seems the consumer must decide on his or her own which product to purchase. In this particular case, honeycomb shades were selected.

Nothing is Exempt

As discussed in our response to a visitor’s comment at the bottom of the Avoiding Damage to Vertical Blinds page, plastic components like carriers, carrier assemblies, and tensioners, dry out and become brittle with prolonged exposure to sun and heat.

The same condition befalls stitching in the pleats and side hems of drapery panels. Even when the recommended monofilament is used. Yes, that’s right. A “medium test” fishing line is the preferred thread for stitching drapes. All too often light duty monofilament, or even all purpose threads are used, and these degrade much quicker. Once the first stitch goes, the rest soon work their way lose until a hem or pleat is completely blown out.

The truth is, any material will eventually succumb to sun and heat. Still, due diligence pays off. To the extent possible, research the quality of any window fashion you wish to purchase. Have windows tinted. Layer treatments, so as to protect the most expensive of them with heavy duty underlying barriers like roller shades or plantation shutters. Also, if you’re the owner of a ground-level home, consider making use of shrubbery, awnings and anything else with the potential to shield windows from the sun.

Fabric window coverings suffer most in the kitchen. Food spatter, greasy cooking film, barbecue fingerprints and the inevitable traffic to the grill just outside, fouled these shades but good.

No problem. Clean as the day they were born, after our injection/extraction treatment.

A “before and after” shot. Shows how much a minimalist approach can transform a space with limited possibilities.

Customer’s selection of Silhouette® shadings was clearly the best option, considering that others would either project further into the room or completely block the lovely view.
