There are many different varieties of Cedar/Cedrus.
Cedars contain resins which generally protect wood from insects & moisture.
But sometimes cedar-resins can stain other-surfaces if not properly kilned/sealed or if soaked with solvents (water, alcohol, ...)
Cedars are a lighter/softer-wood than some hardwoods (oak ...) & tropical-woods (mahogany ...).
