CK 25 sometimes starts??

[Bailer]

So recently my tractor has had issues starting. Been reading posts and playing around with it .
When I turn the key if I hear a soft click and a hard click and let the glow plugs cycle it will start right up. If only a soft click it will crank but no start.
Been playing around with it and tonight I sprayed brake clean and lubes in the key hole and was getting two clicks again. I know if I get two clicks it will start.
Should I pull the key switch/ ignition out and try to clean it out good or just keep spraying in there ??
I was thinking relay or engine stop solenoid but if spraying the key hole is making a difference perhaps not??

Replace the key switch with new OEM, if you’re sure that’s the problem.
You could Keep the old one and clean it up. Now you have a spare…

There is also the common problem of one of the safety switches being the problem.
