Blighted basket toms

I've had to give up and chuck out my Gartenperle because they're well and truly blighted. I use extra big hanging baskets for them every year, with built in permanent coir liners. Am I safe using these again next year or could they carry the blight spore and I need to rip them out and put in new liners?

Blight is carried in live plant material. Coir isn't.

Goodo, because they're so much easier to work with than loose coir liners. Don't know how well I can clean them because coir kind of falls to bits if you get too rough with it, but there certainly won't be anything still living on it by next season.
