A whitewash happens when you use deceit to cover up the messy facts about a situation. A blackwash is just the opposite: It's when you invoke candor as you reveal complications that have previously been veiled. According to my analysis of the astrological omens, the coming weeks will be prime time to enjoy a jubilee of blackwashing. But I suggest that you proceed gently.
Remember that not all hidden information is a sign of malfeasance or evil intentions. Sometimes the truth is so paradoxical and nuanced, it's hard to get it completely out in the open all at once. And sometimes people are motivated to keep things secret mostly because they're afraid to cause pain.
