we have a block-paved drive. after 5 years it is looking a bit mouldy/tired, with a few weeds at the edges. i was thinking about pressure washing and sealing it - but youtube says pressure washing can reduce the life of the driveway....
Whatever you do will reduce the life. Hypochlorite is an easy option - put it on, leave it and rain will do the work.
Pressure wash can be quicker with a big enough washer.
