My stainless steel refrigerator doors are spattered with grease that accumulates over time. I've tried degreasing solutions and even bought one from Lowes for about $15. It didn't work even if I left the solution on for longer than stated on the bottle. After receiving this CLR product (I trusted this brand as calcium builder works great) which I didn't know had anything other than calcium builder, I followed the directions on the bottle and years of building. now they're all gone.
