Step 3:

  • Wipe the bottom and sides of the deck completely with a paint stripper and a towel to eliminate excess oils. 
  • Allow for thorough drying of the paint stripper.

Step 4:

  • With a brush, spread corrosion converter on all deck areas.

Why lawnmower rust?

When uncovered metal on a lawnmower deck is subjected to air and moisture, rust develops. To avoid corrosion from chewing through the metal completely, it’s critical to address a rusted deck as early as the problem arises. 

The use of a corrosion converter transforms existing corrosion into a dark protective layer, eliminating the need for a primer prior to painting your deck.

How do lubricants work in removing rust?

Lubricants will lubricate the trailer surface areas, avoiding rust by inhibiting water from reacting (passing) across them. To assure that the lubricant works properly, clean all areas of the lawnmower before spraying it (ensure everything is dry).

Sprinkle the lubricant anywhere you want it: on the lawnmower, base, blades, and so on. You don’t have to sprinkle on top of the lubricant if it was applied before and some lubrication is left (existing) on the surfaces. 

Here are some of the top-recommended lubricants:


Why should one choose these lubricants?


  • CorrosionX is an excellent lube for corrosion protection on your lawnmower.
  • And a good layer would last for many days before washing away. For the amount you’re investing, it’s well worth it.


WD40 is a lube that absorbs all water and functions as corrosion protection to keep corrosive materials from rusting. They’re most commonly used on connectors.

Avoid over lubrication:

The point is simple: oil the lawnmower parts if they aren’t adequately greased; otherwise, don’t grease them. Heavy lubrication might collect dust and detract from the appearance of your mower. So, don’t grease them too much, or at the very least wipe them before lubricating.

Allow the mower to get dry and grease it once more:

  • The lubricants will grease the trailer surfaces and do not allow water to pass through their surface that resulting in inhibiting corrosion. 
  • After washing the lawnmower do not directly apply any lubricant because the mixture of moisture and lubricant can trap dust. 
  • Please give sufficient time to dry the lawnmower after washing, and then use lubrication mists (if required) on all the components of the lawnmower. 
  • In this way,  the lubricant will effectively lubricate those components.

Because all of these products will run away with time, you must check and re-apply them on a regular basis. Cleaning the greased surfaces will quickly remove the lubes. Above all, use them on dry surfaces (parts) rather than damp ones.

Step 9:

  • Now is the time to reinstall the mower once you’ve finished greasing the blades and housing. 
  • Reconnect the blades, making sure it’s tightened completely. 
  • Place the mower straight once the blades are set and snug. Reconnect the spark plug cable to the spark plug. 
  • After that, fill up a gas tank and the mower is good to use again.
  • Cleaning the mower blades doesn’t really take much time, but if done correctly and on a routine basis, it will extend the life of the lawnmower and improve its performance. 
  • The blades will be razor-sharp and cut the grass to the proper height.
  • WD-40 put on the blades will keep them free of corrosion and dirt, keeping them in good working order for a long time.
