So, how do you pressure wash a riding lawn mower engine without getting water in it? First, make sure that the engine is cool before you start. You don’t want to pressure wash an engine that’s hot because that could cause serious damage.

Once everything is exposed, start by giving the whole thing a once over with low pressure just to loosen up any dirt or grime that might be caked on. Now it’s time to get out the high-pressure nozzle and start scrubbing away. Be careful not to aim directly at electrical components or anything else that could be damaged by high-pressure water.

When you’re finished washing, make sure all of the parts are dry before putting everything back together and reconnecting the spark plug. If done correctly, pressure washing your riding lawn mower engine can help keep it running smoothly for years to come!
