Professional Cleaning!
Did you know glass is a very slow-flowing liquid? So it is
important to keep your windows clean with the proper cleaning
techniques. Dust and dirt are very abrasive and can damage the glass
surface.
If you have ever watched a professional window washer, you
probably did not see him using a spray bottle and a roll of paper
towels. This technique removes much of the abrasive dirt, but some
of it is just spread in a film over the glass. It may look fine at
night, but when the sun hits it, it is a mess.
Every good window washer has four basic tools: 1. Lamb’s wool
scrubber, 2. Water and detergent, 3. Squeegee, and 4. Lint-free
towels.First use a wand to soak the window with solution. A
medium-to-long-nap fleece lamb’s wool scrubber is effective for
applying the soapy solution and is a must for a good job. The key is
to get the scrubber well saturated with the solution so that it
picks up the majority of the dirt as it floods and rinses the glass.
You want the window to stay wet for as long as possible, especially
if it is in the bright sun. (And we avoid cleaning windows in the
bright sun. We always try to work in the shade.) Just let the
windows soak for a little bit and soften up the dirt. If it starts
to dry a little, we scrub and wet it again just before we squeegee
it off. That way, when the glass is squeegeed dry, only clean
solution is being squeegeed off.
Remember that glass is relatively soft and porous, so rubbing it
hard with dirty paper towels (or a kitchen scrubber) can scratch and
dull its surface over time. If you want the cleaning solution that
the pros use, you can find it at any janitorial supply store. Or
make your own with a bucket of warm water and just a teaspoon (too
much soap can cause streaks) of a good dishwashing liquid.
If some of the windows still have some specks of cement, paint,
bug spots, or tree sap on them, try using your thumbnail and lots of
soapy water. A scraper can help, but look out! If you do try a razor
blade scraper, always make sure that the blade has soapy water for
lubricant, and that the window is wet with soapy water as well. A
dry blade will scratch the window. Always use a new blade that has
no burrs that may scratch the glass.
The third tool is a high-quality, professional squeegee with a
brass body (12-18“wide) and replaceable rubber blades. Brass is a
relatively soft metal, so it will not scratch the glass unless you
bump it hard. Using the squeegee properly to remove all the water is
a very important step. Every drop you put on the glass, has to come
back off, or you're leaving dirt on the window.When you can, use a
horizontal pass across the window starting with your squeegee at the
top. If you are using a pole, you can squeegee from top to bottom
tilting the squeegee down on the dry side so that the water flows up
to the still wet area. After each stroke, wipe off the squeegee with
your lint-free towel (most paint stores sell these). Overlap each
stroke by about two inches for the best results.
When you are done with the squeegee, use a blue hospital towel,
which is very absorbent, lint free and reusable. Terrycloth is a
good second choice. Don't waste time using a damp towel; it won't
get every drop. Keep a supply of dry towels on hand, and switch
often. Wipe the towel down each edge of the glass and across the top
to remove any drips before they drip.
Then step back and enjoy the good feeling we all get from
