How do you protect your iron and board from starch? Sewing Machines Parts and Sales in Los Angeles

I like to use a starch spray to press my seams, especially when quilting. But lately my iron has been getting gunky and my ironing board is becoming stiff. At this point I’m going to have to recover my ironing board. And I don’t want to have to buy a brand new iron!

I use about 1/4tsp of starch per half cup of water.

Any ideas on how to protect my iron and board? Am I using too much starch?

Any advice is helpful. Thanks! 🙂
