Beinahe ein Jahrhundert Zigarettenrauch, „schmutzigere Heizmethoden“ und Hautöle von Besuchern an den Wänden hatten das cremige, frische Aussehen, das der Stein normalerweise aufweist, verdunkelt. Premium Plant Services und Sponge-Jet arbeiteten zusammen, um die Reinigungs- und Restaurierungsarbeiten des zweistöckigen Projektes auszuführen. Während sich die Ergebnisse sehen lassen können, war es der Architektin und dem Hausmeister außerdem wichtig, dass die Einrichtung, mikroabrasive Reinigung und alle Aufräumarbeiten am Einsatzort in der Nacht stattfanden, um den Tagesbetrieb nicht zu beeinträchtigen. Frau Rayala machte den Worten von Brady Slater, Redakteur der  *Duluth News Tribune*, zufolge das beste Kompliment, als sie zu den anderen, nachfolgenden Renovierungen von Gebäuden der Stadt sagte: „Wenn sie sehen, was wir geschaffen haben, werden sie es uns allen nachmachen.“ [**Klicken Sie hier,**](http://www.duluthnewstribune.com/news/3781380-after-nearly-90-years-duluth-city-halls-walls-get-deep-clean) um den Artikel zu lesen und das Video anzuschauen, die die Arbeit der beiden Unternehmen würdigen. - [Tweet](https://twitter.com/share) Search this site on Google Search Google ### Categories ### Recent Posts ### Sign up for our blog. ![](https://blog.spongejet.com/hubfs/Spongejet-Oct2015-Theme/Images/find-rep-bg.png) ![](https://blog.spongejet.com/hubfs/Spongejet-Oct2015-Theme/Images/find-rep-img.png) [Distributor Locator](https://www.spongejet.com/find-rep/) ![](https://blog.spongejet.com/hubfs/Spongejet-Oct2015-Theme/Images/white-paper-bg.png) ![](https://blog.spongejet.com/hubfs/Spongejet-Oct2015-Theme/Images/white-paper-img.png) [Resources](https://www.spongejet.com/support/resources-support/resource-library/?k=&type=document-library&document-type%5B%5D=24&searchsubmit=Search+resource) ![](https://blog.spongejet.com/hubfs/Spongejet-Oct2015-Theme/Images/online-traing-bg.png) ![](https://blog.spongejet.com/hubfs/Spongejet-Oct2015-Theme/Images/online-traing-img.png) [Online Training](https://www.mytestcom.net/app/myTestcomURL.cfm?accountLogin=SpongeJet123&joinPasscode=SpongeJet123) [![spongejet](https://blog.spongejet.com/hubfs/Spongejet-Oct2015-Theme/Images/logo.png)](https://www.spongejet.com/) - - - - - [+1 603-610-7950](tel:+1-603-610-7950) - [Contact us](https://www.spongejet.com/contact/) Phone: +1 603-610-7950 | 14 Patterson Lane, Newington, NH 03801 USA - [© 2015 Sponge-Jet, Inc.](https://www.spongejet.com/copyright-info/) - [Contact](https://www.spongejet.com/contact/) - [Support](https://www.spongejet.com/support/) - [Privacy Policy](https://www.spongejet.com/privacy-policy/) - [Terms & Conditions](https://www.spongejet.com/terms-conditions/)
