There were no conservation programs developed in Palacio Salvo. Only minor reparations can be observed. In this study it is strongly recommended the design and implementation of a conservation program. Alternative nonaggressive measures are proposed if this program can not be developed.

Cracks related to splintering and chipping should be studied in detail to determine their cause. In general, cracks, fractures (with or without fragmentation), can be consolidated and mechanically repaired after cleaning and removal of loose fragments (Matero & Tagle, 1995). As consolidant Siegesmund & Snethlage (2011) recommend TEOS. For the repair of cuts, perforation, gaps and missing parts it is recommended to prepare patches of different colors, textures and materials, that can replicate the décor of Kösseine Granite, including the different enclaves observed. The metallic inserts should be removed by gentle mechanical means or by using a drill of small diameter to prevent damaging the rock around it.

Deposits weakly attached and spider nets should be removed by mechanical means (soft brush, plastic spatula). Soiling and deposits strongly attached could be removed by steam jet, as described in Siegesmund & Snethlage (2011). Oxide staining could be mobilized by chemical complexing or sequestering agents that can be soaked up or flushed away (Matero & Tagle, 1995). Following these authors, poultices with different chemical compounds could be used to remove oxide staining, grafitti, paint films, and eventually deposits of cement, and others that could not be removed by the previous methods.
