Steam Generator Iron How Do I Clean It ?

Even though you are an Ipswich fan (spit) :D I'll tell you how I did it.
I used kettle descaler on ours, worked a treat. Diluted it down put it in the water reservoir, let it heat up, run it through until you get good steam then leave it half an hour or so to descale the heating element, tip out, rinse out with water then run "clean steam" through - job done.
