Simple Solution to a Complex Problem: तःसी Citron Juice to the Rescue.
In the summer of 2010 CE, the local community of Janabahā achieved incredible results while cleaning the exterior of the Janabahā Dyo temple in Kanaka Chaitya Mahāvihar, Kel Tol, Kathmandu.
The cleaning activity's most striking accomplishment was the polishing of the हलं पौ halam pau (gilded copper banners) hanging from the roofs of the temple using a common homemade cleaning agent.
To preserve the authenticity of the centuries-old archeological material, no chemical agents were used in the cleaning process. Instead, indigenous knowledge was put to use to remove the decades-old dirt.
The community first hired two semi-skilled laborers to put up a bamboo scaffolding to access the decorative metal plates, all bearing beautiful images of holy men. Thick dirt had accumulated on them over decades, primarily from pigeon droppings and exposure to the elements.
The workers then coated the metal surfaces with the ubiquitous चुक पाउँ, made at home with plain तःसी citron juice. They were then left alone for a few days until the natural acid eroded away all the filth, without causing any damage to the metal.
After a simple hosing down with water, the brilliant gold-plated surface was suddenly exposed for all humanity to appreciate.
The two-tiered temple housing the image of Karunāmaya Aryāvalokiteshwor was probably built in the 15th century CE, and expanded in the 17the century CE. Also worshipped as the Seto Machhindranath and Janabahā Dyo, this deity is among the most revered divinities in the historical core of Kathmandu city.
The cleaning was led by late Tirtha Dhar Tulādhar, a social activist who spent much of his life working for the betterment of the Janabahā monastic complex. He passed away in 2013 CE.
The temple exterior has not been cleaned since the last thirteen years. The holy metal has become grimy, grubby and greasy once again.
