Rarely Any Cleaning Occurs
It would be surprising to note that the monument does not require too much cleaning compared to maintaining. The reason for this is because the budget constraints had made it possible for the cleaning got to take place only at extremely crucial times and does not happen often. But back in the year 2005, a pressuring washing company named Kärcher did the country a huge favor. They did so by cleaning up for free with their own equipment that went on for a few weeks making use of pressurized water at over 200 degrees. This was probably the only time that the monument had ever received a thorough cleaning ever since it was opened in the year 1927.
