A few weeks ago, I went to the front of the school to clean the historical marker. The street side was so covered with gray lichen that it was barely readable. For some reason the back side was not nearly as bad. So I cleaned the front side just using soapy water and a heavy duty cellulose (course) sponge. I got 90 percent of the mess off the sign. That took a lot of time because of trying to get in between the individual letters, etc. I left the back side (facing the school) alone.
A few days later, I went back to the school for Round Two with the historical marker. This time I used a combination of soap and water, Wet and Forget (cleaner) solution, Windex cleaner and auto tire restorer spray. Now both sides of the marker look great and almost looks totally restored. I have posted some Before and After photos! Note: the LHS Corporation had the historical marker made and placed on the front lawn of Old LHS about 30 years ago and I am sure that this is the first time it has been thoroughly cleaned!
