Using starch - cleaning the iron afterwards
I’ve been using a lot of starch on my current project because it needs to be very accurate and includes a lot of sewing on the bias. Now my iron is leaving dirty marks on the fabric. I think it’s too late for this particular iron - it already had a build-up of residue on the plate - but, before I buy a new one, how do you stop starch from messing up the bottom of your iron? I’ve never found a really effective way of cleaning it.
