Maintenace of Keris

MAINTENANCE
A good tosan aji warang can last years. It is custom to oil tosan aji every Kliwon Tuesday or Kliwon Friday with diluted sandalwood oil. Keris should not be kept in a humid place. If it is must be stored in a closet/cupboard, it should be placed vertically on the top shelve. Fermentation of coconut oil will produce acid powder and other acids. To prevent this, keris is by mixing with gandapura oil. The mixture is 100 cc of coconut oil and 10 to 15 cc of gandapura oil. Besides sandalwood, kanthil, jasmine, or kenanga fragrance can be used. In Keraton Yogyakarta, the mixture of coconut oil and sandalwood oil is 1:1. For the method used in Solo, the mixture of krengsengan oil, kenanga oil, and gandapura oil is 25:10:3.
Riffle oil can also be used, but many specialists of esoteric keris say that the use of mineral oil will decrease the esotericism of keris. It is only used for last resort.
Keris are never to be sun dried for drying the oil. Otherwise the metal structure and mystical powers will fade. The brushing process should be done softly especially for keris plated with gold. Tosan aji should not be soaked in coconut water. Otherwise it will be corroded.
