Hello,
Does anyone know a foolproof method for cleaning and keeping clear block
paving footpaths as mildew soon reappears.

I use a high pressure hose once a year. Keeps all my paths and paving
stones clear for the summer. From late october onwards the nasty stuff
starts to re-appear, but then in March I blast it away. Surprisingly
does not use too much water. It takes me about 8 - 10 hours and I use
about £2 worth of water.

8-10 hours??! How many paths do you have?
