D/2 Biological Solution

Cleaning of the union soldier monument at the historic Morristown Green, Morristown, NJ. Erected in 1871, this is likely the first time that the monument has been touched. There was a whole lot of lichen.

D/2 was applied top to bottom. Lichen and algae scrubbed with brushes. Then water rinsed from spray bottles (hose hokup not available). Then a final application of D/2 left in place. 100% top to bottom.

Jonathan Appell, a D/2 distributor, is doing a 48 State (+DC) cemetery workshop tour. One of our staff attended his workshop in Palenville, NY on August 24, 2020. A small local cemetery with an attendance of around 35 people. It was a pleasure to spend the day watching Jonathan do a stream of consciousness kind of ongoing instruction. One of his sponsors is D/2 biological solution.

Ted Kinnari attended Columbia University’s Historic Preservation Program and was in the first class Norman Weiss taught at CU. He served as Alumni President, Adjunct Professor and was an early recipient of the Alumni Award. After graduate school he worked for the Brooklyn Museum and then the NY Public Library and was responsible for running their restoration programs. After leaving the Library, Ted started a restoration construction/consulting firm. One of the firm’s projects was to write specifications for the cleaning of Grand Central Terminal's Celestial Ceiling murals. This experience, and his prior involvement with facade cleaning at the NYPL and Brooklyn Museum led to an interest in developing a better, safer product for facade cleaning. After several years working with Norman Weiss, D/2 Biological Solution was created. D/2 has now been in use for more than 20 years. Ted is the president and owner of D/2 Biological Solution Inc.
