How To Clean A Lawn Mower Using Pressure Washer

The kind of job your lawn mower does in cleaning and trimming your lawn to give it that well-maintained look certainly gets your lawn noticed in the neighborhood. And why not? Today, this efficient gizmo is an indispensable member among your other household devices. But, this efficiency takes its toll on the lawn mower. Although sturdily built, its constant use can leave it with ugly build-up of dirt and grime, grass and other deposits.

If these accumulations are not immediately removed, they can solidify and stick to the machine, jamming it and making it look unattractive. One of the most disliked job is to clean this muck by hand with a damp cloth immediately after use. However, you don’t have to do this, if you have a pressure washer at home. Pressure washers have proved most efficient in cleaning lawn mowers, leaving them sparkling (steam cleaners are best to clean lawn mowers, too). So how to select the best pressure washer?

1. Check if the pressure washer is PWMA Certified

2. Opt for a light-duty pressure washer for basic cleaning activities at home. A medium-duty power washer is well suited for purposes like cleaning fences, driveways etc. You may need to consider investing in a heavy-duty model for tough jobs like stripping paint.

3. Electric pressure washer can be used for basic residential activities.

Cleaning your lawnmower regularly is part of its maintenance schedule. You need to rid it of all types of dirt and deposits to keep it in working order. One of the most efficient ways of cleaning a lawn mower is to use a pressure washer.

Advantages of a pressure washer

As compared to other cleaning options, a pressure washer holds many advantages in cleaning a pressure washer. Let us see what they are:

  • High pressure: This enables the pressure washer to conveniently get rid of dirt, mud, grime, grass, weeds that sticks to the lawn mower blades and base during use.
  • Blasting capability: Even if the dirt, mud and grime has solidified on the lawn mower, the blasting power of a pressure washer chips away such accumulations most efficiently without damaging the device.
  • Better reach and maneuverability: The long and flexible hose of a pressure washer and its water jet accesses parts that are difficult to reach by other means. It can effortlessly remove the build-up and deposits that accumulate underneath the mower deck.

Understanding the working of pressure washer

It is important to understand that pressure washers are power machines and require certain level of expertise in handling. So, before you set out to clean your lawn mower, it is always good to acquaint yourself with the working of a pressure washer.

Basically, a pressure washer comprises a motor that picks up the water from a tank or a faucet and directs it into a hose that forces it out through a nozzle at extremely high pressures. The water so ejected by this pump system at high pressures manages to remove dirt, mud, grime, grass blades and other deposits from the lawn mower blades and other parts.

The best part of the pressure washer is its set of nozzles that regulate different pressures and can be used for all kinds of surfaces. For this, it is best to have a look at the user manual.

Setting up the pressure washer

Like any other device, a pressure washer too requires setting up. If it is an electrical device, check the plug connection and all other connections including inlet and outlet. Firmly secure the hose to the spray gun and keep the accessories handy that you might use during lawn mower cleaning. In case of a fuel-driven machine, ensure that it has the right amount of petrol or gas for the cleaning operation.



Make use of cleaning solutions

Although in most cases the pressure of water suffices in ridding your lawn mower of dirt and grime. But, sometimes this muck is so caked up that even this pressure is unable to do a thorough job of cleaning.

In such a situation, cleaning solutions, preferably eco-friendly green solutions, provide the answer. Once you apply the solution, let it sit for five to ten minutes. This helps soften up the stubborn and tough deposits, making it easy for pressure washer to clean.

Cleaning the lawn mower

As a first step, disconnect the spark plug and the blades. If it is a push mower, prop it up to clean the underside of the deck. In case of a riding mower, use a lift to expose the underside for cleaning.

Start the pressure washer and direct the nozzle on to the dirt, grime and other deposits. Apply appropriate water pressure and work your way from top to bottom.

Take care to decrease the pressure of the nozzle on the sensitive parts of the lawn mower, so as not to damage them. In case of tires, keep the pressure nozzle at least six inches away to prevent puncture or damage.

This way you will manage to cover all areas – blades, tires and other movable parts. After thorough cleaning, dry out all the parts and affix the spark plug and reattach the blades.


The efficiency with which a pressure washer cleans a lawn mower is to be seen to be believed. For this, it is important that you choose a pressure washer of a reputable brand that provides a high level of efficiency with minimal manual effort.
