Extensive spider mite damage + virus concern

[BrassavolaStars]

Hello all,

Unfortunately because of the weather, I hadn’t been able to be in my greenhouse that much to monitor the plants. This mini Dendrobium nobile now has a very bad case of mites. When I looked at it closely, it was covered in webs. I just washed the entire plant in soap water. Was that okay? The leaves look fairly damaged. 3 plants total have been affected though the one pictured is the worst hit. The leaves on this plant are also showing Chlorosis. I am concerned this is a virus transmitted by mites. Is that likely? What should I do?
