柏林屋顶的清洁

作为其文化赞助的一部分，Kärcher清洁了柏林大教堂南塔。这项工程是对大教堂正面进行全面整修的一部分，历时四周左右。大教堂位于首都中心，被认为是通往著名博物馆岛的门户，是德国最大的新教教堂之一。

在离地40米的地方工作

"The restoration of the cathedral is one of the central tasks for us in the coming years and a huge project - that we were able to win the Kärcher company with its experience from many restoration cleaning projects as a supporter is of course a great help", said Michael Kösling, managing cathedral preacher about the cooperation. Kärcher removed deposits and encrustations of soot, rubber abrasion and dust that had been deposited on the sandstone over the past decades. The so-called low-pressure particle blasting process was used: from a distance of 10 to 20 cm and with a surface pressure of 0.5 to 1 bar, the specialists, equipped with breathing masks and protective suits, removed the layers of dirt with an aluminium silicate blasting agent.

这种方法是由国家文物保护局事先规定的，并在初步检查中得到确认。”虽然这里使用的程序是非常昂贵和耗时的，它也是非常有效和温和的物质。随着南塔立面清理工作的恢复，我们可以在确保柏林重要历史遗产得到可持续保护和保存方面发挥我们的作用，”负责现场协调工作的Kärcher项目经理Nick Heyden在解释公司承诺时说。

与Stiftung Denkmalschutz筹款

的改造,从而也清洗cathedral façade became necessary because façade damage was discovered about two years ago. "The damage was caused by soot, rain and exhaust fumes, among other things. In addition, penetrating rainwater has severely damaged the masonry and the sandstone substance of various decorative elements and figures on the cathedral", adds monument conservator Damaris Gorrissen. Last year, the cathedral parish was already able to win over the German Foundation for Monument Protection for a joint campaign for the restoration of the façade. Nationwide, donations amounting to 167,000 euros have now been received by the foundation. In total, the community needs 1.6 million euros for the renovation. Berlin Cathedral is one of the largest Protestant churches in Germany and, with the Hohenzollern crypt, houses the graves of numerous members of the Brandenburg-Prussian imperial dynasty of the House of Hohenzollern.
