Followed this article with interest. I solved the misting problem by
1. Removing the old desicant beads by drilling a hole in the edge of the cell (don't drill all the way through)
2. Use a airbed pump to replace the air (the alloy metal edge contains small holes that allows air to pass through)
3. Replace the desicant with silica cell (widely available from craft shops or ebay)
5. Reseal the drilled holes
6. Optionally paint the edges with roof sealant or similar
Optionally I've started using Argon to replace the air in the cells (again available from Mig welding suppliers) - this is heavier than air and has low thermal conductivity.
Result - windows have been free from mist from several years so far.
(P.S. I've found I can clear water stains by pouring meths into the cell then drying out by pumping through air for 20 mins)
One question I have though - is where on earth do you buy replacement glass units if needed - can't find a single supplier who will just sell the glass units!

i'VE just watched a video from crystal clear about this. The fitter drilled a couple of holes in the glass and ran a ballbearing inside the glass gap with a magnet. He squirted water inside the gap to clean them and then put valves into the holes. Can't see though why it will not mist up again as the original problem is not fixed. Will these valves create some sort of equilibrium which will stop the condensation. I'd have to see one 9 months later.
