I have found the best way to get rid of algae weeds etc between paving
stones is with a wire brush - chemicals do not seem to work -
Is there any suitable solution (to reduce the speed at which weeds algae
come back between the slabs) which perhaps I can immerse the brush in
when raking out the muck between the slabs ?
Your help please

There is no effective chemical treatment that will prevent both weeds
and moss/algae from returning. A residual weed killer such as
Pathclear will stop weeds for about 3 months but this should be
sprayed down the gaps - it won't work if you dimply dip the brush in
it.

You'd be better off filling the gaps between the slabs. If a small
area you can trowel a concrete mix into them; if its a bigger area one
option is to (on a dry day!) get some fine ready-mixed sand and cement
and brush this into the gaps until almost level with the slabs. Then
using a hose head on a GENTLE sprinkler setting, or preferably a
watering can with a medium rose, GENTLY wet the area (if you don't do
it gently you'll simply wash the mix out of the gaps). Or get one of
these:
