"Back in the day" automotive air filters were wire mesh & Brillo pad material. Every 5,000 miles you were RECOMMENDED to "wash in gasoline to remove particles trapped in the dirty oil" & then dry & re-oil to use again.
We decarbonized 2-stroke mufflers with gasoline, a length of chain & a potato!
Yup! You removed the muffler, pounded a potato onto one end to seal it temporarily, dumped in about a pint of gas & shook/let stand to dissolve the oil & soften the "coke" or carbon.
Then you chained it to a solid post with anchor chain, poured out the excess gas, removed the potato & lit the gasoline-soaked muffler!
What happened was the gas air mix was too rich to burn inside the muffler so you got a candle flame at the end, at least till the now hot muffler reached the magic 15:1 air/gas mix internally, then BOOM! the explosion vented from the open ends blasting the baked dry carbon out. Once it cooled down you re-attached for another 500 miles or so.
As long as the chain & post were solid you even kept all your fingers & toes. Ah yes! Those were the days, imagine even suggesting that now
