Brick House Repair/Cleaning

[Mason Magness]

A house I’ve put in an offer on has some damage and cracking in the bricks that was covered over with this white mortar (not sure if that’s what it’s called) that is just caked onto the larger cracks. I’m assuming this was caused by movement in the foundation (still need inspection from a professional to determine the severity) and I was wondering what the options are for making it look less tacky? Also, can you pressure wash brick homes or is there some preferred method of cleaning the exterior? Thanks in advance!
