Is it fine to clean bearings with gasoline?
Gasoline was used for many years as an inexpensive readily available solvent. There are a couple of real life issues with using gasoline for a solvent. It is very flammable thus a fire hazard. It is absorbed through the skin and it is toxic when inhaled in high concentrations. You have to find a way of disposing of the remaining dirty solvent. Pouring it on the ground can contaminate drinking water. If you have no other means of cleaning the bearings you can wipe them with clean rags. That still leaves the issue of disposing of the dirty rags .
