Ask your QuestionWhat can I do about bricks that contain surface debris? I’m talking about debris like moss, mould and dirt. Is this to be expected or should I look after this and clean it/remove the debris? If so, how can I go about this? Thanks.

Other than this I personally wouldn’t do anything else."
"This should scrape off with no problems and then a light jet wash, being careful not to blow out the mortar between the joints."

All the things guys wrote earlier are true. Anyway, there's always something else.
Way of fixing a problem, always depends on reason.
Using a brush only for a wet moss, will make a marks at bricks surface and will not give You expected effect.
Using a pressure without physically removing is the fastest way to collect a moss and all the rest from everywhere around, including neighbours. Steel brush - two moves and it's to be dirty as the things You tried to remove. Chemistry is ok, of course, but will fall down making marks, so You will have to use a pressure anyway.
So, finally, You're to use all the things they wrote, but in correct order, to get a visual effect You want.
Regards."
