It is an ideal companion for the annual cleanup of mowers, tillers, and pressure-washable implements.

The advantage of using a dedicated pressure washer cleaner is the reduced wear and tear on the machine’s internal pumps and seals. Standard detergents can sometimes cause corrosion within a pressure washer’s components over time, but this formula is specifically balanced for equipment longevity. It ensures the wash process itself does not become a source of machine failure.

If a pressure washer is the primary tool for equipment cleaning, Briggs & Stratton’s specialized formula is the logical choice. It provides the best performance for flow-through systems while protecting the machinery being washed. Use this to simplify the cleaning process and protect the pressure washer investment simultaneously.

How to Pick the Right Cleaner for Your Equipment

Choosing the right cleaner starts with identifying the type of buildup: light dust and mud, heavy grease and oil, or organic matter like manure. All-purpose cleaners serve well for daily maintenance, while specialized degreasers are necessary for engine bays and gearboxes. A simple rule is to match the cleaner’s strength to the intensity of the mess to avoid over-applying chemicals.

Consider the surface materials before selecting a product. Most modern farm machinery incorporates a mix of powder-coated steel, plastic, rubber, and aluminum. Always verify that a cleaner is marked as non-corrosive to prevent etching on aluminum or premature hardening of rubber hoses.

Finally, weigh the environmental and safety factors based on where the cleaning takes place. If the runoff heads directly into a garden or water source, opt for biodegradable, plant-based formulas. When cleaning in a concrete-floored shop with proper drainage, more aggressive degreasers are acceptable and often more effective.

Safe Application Tips for Cleaning Your Machinery

Always start by knocking off the heavy debris—such as clumps of mud or dried manure—with a stiff brush before applying any liquid. This prevents the cleaner from being absorbed by the organic matter, ensuring the chemical goes directly to the surface that needs attention. Never apply cleaners to hot engines; allow the metal to cool to avoid rapid evaporation or potential damage.

Apply the cleaner from the bottom up to ensure even coverage and prevent streaking. After spraying, let the product “dwell” for the manufacturer-recommended time, but never let it dry completely on the surface. Rinsing thoroughly is the most important step to ensure no chemical residue remains to potentially cause long-term harm to paint or seals.

Use personal protective equipment (PPE) like gloves and safety glasses, even with non-corrosive cleaners. Farm chemicals, no matter how safe, can cause irritation upon prolonged contact. Always test a small, inconspicuous area of the equipment first if the finish is delicate or vintage.

Degreaser vs. All-Purpose: What’s the Difference?

Degreasers are specialized solvents designed to break down petroleum-based substances, such as grease, oil, and tar. They are usually more aggressive and have a higher pH balance, which is excellent for engine components but potentially harsh on paint or decals. They serve a specific purpose and should not be used as a primary cleaner for the entire exterior of a machine.

All-purpose cleaners are surfactants, meaning they work by lifting dirt and debris away from the surface so it can be rinsed away with water. They are safer for a wider range of surfaces, including paint, decals, and plastic components. They are the daily driver for exterior washing, keeping the finish clean without stripping away protective waxes.

Knowing the difference prevents the common mistake of using an overly aggressive cleaner on sensitive parts of the equipment. Keep a degreaser for the “under the hood” tasks and an all-purpose cleaner for the “visible exterior” tasks. This distinction saves time, money, and, most importantly, the integrity of the equipment’s finish.

Proper Disposal of Cleaning Runoff on the Farm

Cleaning runoff often contains oils, lubricants, and surfactants that should not be allowed to enter the groundwater or local streams. On a small-scale farm, ensure the wash area is set away from wells, ponds, or vegetable production zones. Gravel pads or grassed areas can help filter out some contaminants, but they are not a substitute for proper containment.

If working in a shop, ensure the drainage flows into an oil-water separator or a system that collects waste for proper disposal. Do not hose heavy grease runoff directly into the soil. Collecting the worst of the grime on rags first can significantly reduce the amount of chemical that ends up in the wash water.

Responsible cleaning is part of the broader commitment to sustainable agriculture. Taking the time to manage runoff is not just a regulatory consideration but a way to protect the farm’s most valuable asset: the land itself. When in doubt, prioritize containment over convenience.

Maintaining a clean fleet of machinery is an essential part of effective farm management that pays dividends in equipment reliability and resale value. By matching the right non-corrosive cleaner to the job, you protect your investment from the slow damage of environmental buildup and neglect. Keep these products stocked and follow safe application protocols to ensure your equipment stays ready for whatever the season brings.
