Sparkplug, too rusty to replace?

[BiggerZ]

Engine displaying signs of worn spark plugs so decided to replace, pulled off the HT leads to find bright red rust flakes in the spark plug wells, sprayed with penetrating fluid and had a bit of a clean with a rag and hoover but still looks like it’s been pulled from the bottom of the North Sea . Do you think I should still have a go at replacing or take straight to garage?

A garage would probably blow out any loose bits with an air hose, perhaps try a can of compressed air

run the engine up to full temp and attempt to move them when hot
