Surface Dirt and dust was removed using dry cleaning methods such as soft brushes and a museum vacuum on low suction with a net guard covering the nozzle.
This was followed by wet cleaning the surface of the pediment with Tri-Ammonium Citrate 2% in distilled water as it was the most affective in removing the engrained dirt and did not affect the state of the oil gilding. Acetone was used to treat the water gilding.

Once the gesso had dried it was then sanded down to make it smooth, level and matched the original appearance of the corner
Conservation of the Bottom-Right Hand Corner
Removal
The bottom left hand corner had suffered from damp, which had caused the plaster that held the wooden corner in place to crack and fall away.
The wooden corner was removed and the remaining damp plaster was also removed from the frame using a scalpel. This was done so that when the wooden corner was reattached it would sit level with the frame.
Applying gesso to the exposed wood and broken corner
The corner was built back up again using gesso. Rabbit skin glue was brushed on the surface of the exposed wood before the gesso was applied. The Gesso had to be build up in several layers to ensure it had the same height and depth as the original plaster.
Once the gesso had dried it was then sanded down to make it smooth, level and matched the original appearance of the corner
Moulding
The wooden corner was then reinstalled back into the corner of the frame and nailed securely into place. The paint that also covered the exposed wood was removed.
An identical mould was found that matched the original decoration of the corner. Composition was used to recreate the decoration before it was cut to fit the corner.
Once secured to the exposed wood it was then nailed into place to make sure it does not move in the future.
The exposed wood was then covered in gesso and sanded over to make it smooth
