Diamonds Enhancing Image Of Window Cleaning

A jewellers diamond - Diamonds can dramatically enhance the image of a Window Cleaning Company.

The Vision Glass Detailer (Written by Henry Grover Jr.): Diamonds can dramatically enhance the image of a Window Cleaning Company. They can also enhance our service and increase our annual profits. By making it possible to clean glass more effectively in less time. Restoring glass by removing scratches, abrasions, hard water spots, and acid damage. Further;...glass can now be coated and thus protected with thin films of diamond.

The last picture is a micrograph of a weathered window glass surface. We have no use for jewelers diamonds. Yet polycrystalline diamond particles or super abrasives are quite useful. Since they can be used to effectively clean and restore glass surfaces. The picture to the far right shows quite vividly how porous ordinary glass surfaces can become over time. Oily fingerprints, pizza grease, or just dust will fill these holes, valleys, and tunnels. Making it impossible to effectively clean the glass using typical cleaners. But when we add a microcrystalline super abrasive to our cleaning solution we get much better results. Those ball like polycrystalline diamond particles with hundreds of sharp edges each, will reach down into the surface and dig out all acidic contaminants.

Polycrystalline diamond particles are also quite effective at lapping flat glass with the right tools. Creating what are called precision surfaces. Such particles are very effective owing to their size, shape, purity, and hardness. Some are even friable. Which means they actually break up into smaller particles when used. These smaller particles give the surface a smoother feel and appearance. So diamond can be used to restore window glass.

Ways have been found to ‘functionalize’ certain diamond particles with specifically reactive chemical species. These custom made particles will then bond to themselves and the chemistry of precision glass surfaces. Forming protective thin films. I put it this way because I personally do not believe the manufacturers of this technology adequately emphasize the need to properly clean glass on a microscopic level. Simply because engineering precision glass surfaces requires more expertise which limits the size of their market. Even the professional market just wants a ‘wipe on wipe off’ product. In reality this is not practically possible.

I am just beginning to bring the technology of super abrasive engineering of precision glass surfaces to the window cleaning industry. This is a field that has existed for a long time in the optics industry. It is highly scientific. If it were not we wouldn’t be able to look out into the unbelievable depths of space at the stars, galaxies, and quasars. Or down to the farthest reaches of the microcosm where living cells thrive, divide, and work together to create our bodies. Quality glass surfaces are critical to the proper functioning of lenses and mirrors. They are also to our work. My hope is that many will follow me.

Diamonds Aren't Forever For Window Cleaners

Clean getaway for window washer? Not this time! A recent police sting allegedly caught Michael S. Kates stealing jewelry from a Muncie home. A Muncie man who once referred to himself as a role model has been accused of stealing jewelry from the homes in which he had been working as a window washer. Michael S. Kates, 42, 8424 W. Ashford Lane, is preliminarily charged with five counts of theft, each a Class D felony carrying a standard 18-month prison term.

According to Muncie police Det. Jim Johnson, Kates has been suspected of thefts from several homes over the past year. Johnson said Kates gained access into the homes by working as a self-employed window washer. "He did the work," Johnson said. "And, by most accounts, people were happy with his work." Although Johnson said Kates' name "kept coming up" as a possible theft suspect at several homes, city police investigators did not have enough evidence to arrest the Muncie man until an Oct. 6 police sting.

According to a probable cause affidavit, a homeowner on North Riley Road allowed Muncie police investigators to set up surveillance equipment in his home. On Oct. 6, the homeowner -- who had suspected Kates was involved in a previous theft from his home -- contacted Kates and asked him to wash his windows. Johnson said investigators watched from the house next door as Kates was observed going into a closet and removing what appeared to be jewelry boxes. When he left the house, he was approached by officers, who reportedly found the jewelry from the house in one of his pockets.

He was taken in custody and questioned by investigators, where Kates allegedly admitted to stealing jewelry at the Riley Road residence that day and at an earlier date while working as a window washer. Kates was also questioned about other thefts during the interview, according to the affidavit. He reportedly admitted to stealing jewelry from a house on North Morrison Road, but denied stealing jewelry from another residence on North Wheeling Avenue. Det. Johnson said he hopes circulating Kates' photo and charging information will encourage other possible theft victims of his alleged window-washing theft scheme to come forward.

Delaware County Sheriff's Office investigators and Yorktown police have also questioned Kates about similar thefts in their jurisdiction, according to the affidavit. Kates' most recent arrest is not his first brush with the law. In 1997, Kates, a former substance-abuse case worker with the Delaware County Community Corrections program, was sentenced to 15 months in jail after court documents indicated he stole amounts ranging from $20 to $50 on eight occasions from DCCC clients. Kates reportedly kept the money -- intended to be user fees from the clients -- and tried to hide his actions by falsifying financial documents.

A State Board of Accounts audit found theft of "not less than $2,493," according to records. His sentence in that case was later reduced to 90 days by Special Judge Tom Diller of Jay County. Then, in February 1990, Kates pleaded guilty in Delaware Circuit Court to dealing in cocaine. His sentencing hearing drew a courtroom full of supportive friends and relatives, and Kates received a six-year suspended sentence, according to The Muncie Evening Press archives. Kates discussed his rehabilitation in an April 1991 article in The Muncie Star, saying he had been in the early stages of a career as a rap music performer -- under the name "Lemondrop Box" -- when he ran into problems with the law.

"We were going to be professionals, but I saw it was the Lord who did it," Kates said. "He needed somebody like me to be a role model." Kates has also worked at the Youth Opportunity Center in Muncie, serving as a child-care worker and participating in a class for teens in trouble with the law. A driving-while-suspended charge is pending against Kates in Yorktown Town Court. In December 2010, he was convicted of criminal conversion in Delaware Circuit Court 3. Kates was being held Wednesday at the Delaware County jail under a $30,000 bond.

Window cleaner charged with theft of diamond earrings: An Iowa City window cleaner has been charged with second-degree theft after he allegedly stole a pair of diamond earrings from the home of a client June 14.
