If lawnowers gears have a grease fitting no, you are still best using
what is recommended, For kids bikes you would need to take the chain
and soak it in gasolene to remove old oil, rain may remove it quicker
than oil plus it wont last as long, I have dry lube from 20 yrs ago I
rarely use it. For your bike maybe yes but its hard to know when it is
worn off. Door hinges car and house may be good or sticking windows and
door frames or locks.
