Rust happens! Some is easy to deal with, a bit of elbow grease and some low impact cleaning products works wonders!
But sometimes the rust is just too deep to come back from, even with a grinder.
Hot plates can become pitted, if rust is left unchecked. The pesky divots that form reduce contact with your pan, and heat transfer. Making the hotplates less efficient and more expensive to run.

Bob did just that earlier this year "New hot plate - I was wary of replacing this very heavy part but Blake & Bull answered all my questions so I felt confident enough to tackle it. I was shocked when an item weighing 30 kilos was delivered free!! Spot on service!" June 2019
There are other less weighty but equally impactful cast iron parts that can replaced too!
This is a grotty old expansion ring next to a shiny shot blasted one! I did have a go at cleaning one using our super useful wire brushes, and it did recover from the rust really well. But if I had cleaned, scraped, and refurbished my cooker, then I would put a shiny one in!
And to insulation, protect, and seal its underside? A pleasing cosy coil of plump rope seal! This prevents debris dropping through to the rock wool / modern insulation (if you have upgraded)below, and gives your insulation a boost - improving efficiency!
