Well, well! Thought 3 in 1 was straight SAE 20 oil or was when our Mam squirted it on everything. Sewing, machine, our bikes, Dad's alarm clock, the shed door hinges etc etc
Always thought lube oil in the wood would oxidise and stain it black.
Thanks for the info. Going to have a play.
Is the 3 in 1 just soaked into a cloth and wiped or rubbed hard please?
