A glass palace fit for real Vikings

> A cleaning object in a class of its own: The U.S. Bank Stadium

> 18,581 square metres of glass surface

> The five largest glass doors in the world

> Innovative glass cleaning tool

Opened in 2016, the U.S. Bank Stadium is home to real Vikings. Here the National Football League team the “Minnesota Vikings” train and play. The special feature of this opulent, almost one billion Euro venue in Minneapolis is: The roof, front and doors consist of 18,581 square metres of glass, which correspond to almost three football fields. How are these cleaned? Of course, with cleaning tools from UNGER!

Since 2013, 8,000 people have been working a total of around four million hours to complete this major project. The 66,000 seat venue cost around 956 million Euro. The U.S. Bank Stadium is one of the few NFL stadiums with a closed roof. Therefore, as the entire south side of the roof is glazed, tons of daylight enter the interior. The only prerequisite for this is, of course, clean glass surfaces!
The real highlight of the construction is located on the west side of the stadium: the five largest glass doors in the world. Hydraulically swivelling, they cover an area of almost 3,000 square metres and offer visitors a unique entrance experience.
There are also numerous glass surfaces inside the stadium, in the Vikings suites, the arena and the various entrances. To clean this without any streaks is a Herculean task that can only be achieved with an innovative glass cleaning tool.

Four to five men are kept busy every day just with the cleaning of the indoor window surfaces. Here, it is important to remove the fingerprints and soiling caused by the numerous visitors. The innovative UNGER Stingray system is used for this purpose. With the UNGER Stingray, professionals can achieve perfect results and can work 25 percent faster than with a spray bottle and cloth. "The product is designed to get into all corners easily. It is easy and manoeuvrable,” says Cleaning service manager Ed Reynolds.

The lower outer window façades are cleaned with pure water, which leaves no streaks. Thanks to the HydroPower pure water filter and nLite water fed pole system from UNGER, work can be carried out comfortably, safely and efficiently - even up to a height of 20 metres.
Professional industrial climbers access the upper façade surfaces via cable access technology. The model for this approach are modern skyscrapers, such as the Burj Khalifa in Dubai.
"It is the hardest job that I have ever had - but it is a great challenge," Reynolds concludes with a laugh.

Pros placing their bets on the “Dog Earring”

A trend has firmly established itself amongst professional window cleaners: they are single-handedly bending the ends of their squeegee channels downwards with a pair of tongs to improve their performance.
