at our paint store there is a small tool with a semi circle on one side and a sharp set of spikes on the other, you get the majority of the paint off with the spikes and after that a paper towl, then put the brush in a large ziplock bag that's airtight and the brush will stay soft. if you want to clean the brush to use with other paints, the orange handsoap powder that you get at a hardware store will suck the oil right off, but make sure to really rinse the soap off before you use the brush again.
mineral spirits.
It may work as gasoline is powerful, but its not ideal. Try linseed oil.
No. There are special brushes for oil based paint.
Yes. Clean and degloss the oil based paint, apply an oil based primer, then apply the water based paint.
Oil based paint is not water soluble and so needs paint thinner to clean the brushes etc.

Only if you paint the food.
First, clean the tile and grout with a harsh cleanser such as T.S.P. Next, apply a bonding primer to the tile with a brush or roller. It can be oil-based or water-based, and you can thin it slightly if needed to get a smooth, even coating. Once the primer is dry, apply your alkyd (oil-based) paint over the primer with brush or roller.
Do you mean oil-based paint? If so, the answer is yes. All doors, window frames, kitchens and bath areas should always be painted with oil-based paint. Reason: They get dirtier than walls and oil-based paint is an easier clean-up.
Clean it with the solvent of the material that you used. If it was an oil-based or alkyd product, pour approx.4 oz of mineral spirits in a plastic mixing cup, rinse brush repeatedly and clean brush w/ a "brush comb". Store brush in original wrapper it came packaged in (higher quality brushes). Keep a lid on rinsed solvent for future use or dispose of according to local environmental laws. For water-based or latex paints rinse w/ a warm water and laundry detergent solution and comb brush and store in same fashion as above.
Natural bristle brushes are best when working with oil based paints.
Because soap and water are NOT oil based. Oil based means you need to use an oil-based thinner to clean brushes and spills. The materials used in oil-based paints are not soluble in water, even with the added surfactant effect of soaps. (Some paint may come off hands as the soap loosens the dead outer layer of the skin.)
