Burst pipe caused water damage to ceiling, been drying out for last 4

I have ordered some stain block which I will use before repainting.
Should i just go with that or should I give the ceiling a clean first
possibly with a mild bleach solution.

At this time of year you need to leave plaster much longer to fully dry
out before you try to seal it or you will be storing up trouble.
Overpainting with a dense white emulsion will usually cover it.
