Cleaning OSC 2 ZWO Duoband filter

I usually clean my Televue eye pieces firstly using the hurricane blower a few times , then under a torch light in a dark room , a few squirts of 99% isopropyl alcohol on a microfibre eyewear cloth and lightly wipe in a circular motion from centre to outside , I check with the torch and repeat only once more if necessary
Im a first time user of imaging filters so would I adopt the same practice for my new ZWO 2 Duoband filter ??
I cant find anything on the ZWO site for cleaning their filters , so Im cautious about the best and safest way to clean them
Any firsthand practical advice is most appreciated
