I only had today to deal with this as I've had to go away again, and haven't been at the property for a while (which is why the scale got bad before I tackled it). Garden centre was shut, so based on the 'horticultural soap' idea, I made up a lathery sponge with Fairy Liquid, lathered up all the stems, then when the waxy bits were soft I scraped v gently with the back of a knife to loosen it all up, rinsed it down, let it dry and then sprayed with Rose Clear which was all I had.
It will be interesting to see what happens! Next time I'm down if there's a recurrance of the problem I'll just cut the rose back hard for the winter and consider it a rejuvenating prune! Thanks for the messages, I love this forum!
