about me

I'm John Adank and I started Crystal Clear Window Cleaning in 2002. With working a rotating schedule at my full-time employer and having additional days off, I decided to take on additional part-time employment. I’ve worked for other employers but I knew I needed something with flexible hours and freedom to make my own decisions. I thought if I could find the secret to cleaning windows that this would be a good part-time job. I soon learned that there really isn’t a "secret window cleaning solution or special formula". It basically comes down to using the right equipment, paying attention to detail and providing great service to your customers. I take great satisfaction in my work and turning customers into friends.

As part of my commitment to improving my business, I attend yearly window cleaning seminars and continually network with window cleaners all over the country to learn about new techniques and equipment. If there’s some kind of new window cleaning equipment and it improves my overall work quality, I probably have it.

As part of my continuing investment into new equipment and procedures, I purchased a Pure Water window cleaning system in 2011. I was the first window cleaning company in the La Crosse Wisconsin area to start utilizing a Pure Water window cleaning system. The Pure Water system is a 5-stage reverse osmosis window cleaning system in which I harness the power of filtered water to clean your windows.

At a cost of around $8,000, this was a significant investment for myself but I wanted to provide exceptionally clean windows for my customers while accomplishing it in a safer manor.

I’ve been using Pure Water window cleaning for the last several years now and it has been the best addition to my window cleaning since the invention of the squeegee. The Pure Water system will absolutely clean your windows like no other method and without the use of chemicals or detergents. It will not harm your plants or homes exterior. It’s hard to believe the cleaning power of water alone but you will be amazed by the results.
