Sorry to hear that Paul. I grow my toms outside so I'm not sure what to advise re greenhouse cleaning, but someone will come along and tell you.
However, I can tell you that this year I'm growing Crimson Crush, which are supposed to be blight resistant.
I also started several other varieties and swapped some with a friend as we do most years - she gave me some young tom plants that she'd started in her greenhouse and I put them in my mini-greenhouse with my Crimson Crush as the weather wasn't yet warm enough for them to go outside.
Within 10 days all of the plants she'd given me had blight and had to be chucked. I phoned her and she said nearly every plant in her greenhouse had succumbed and had been thrown away.
My Crimson Crush are the only tomatoes that have not gone down with the blight despite having been in very close proximity (touching) the infected ones for at least ten days. They are now strong healthy plants and are fruiting well.
My suggestion would be that next year, if you're concerned that blight might be lingering in your greenhouse, try growing Crimson Crush.
