What about Hydrogen Peroxide? It should be readily available in your area.

Your grow area is wonderful and so organized, Richard! I agree with what has already been said about the cattleya. Repot and remove the squishy roots. I have had cattleyas in much worse shape survive. Your should be fine with the care you are taking with them. What a great thing for that florist to do. Best of luck with all of them!

Cheers,
