How to Clean an Engine Block

Cleaning your engine block can be a challenging task as you might be very concerned on damaging other elements of the machine. Fortunately, it is easy to remove rust and dirt off your engine block as long as you’re knowledgeable on the right cleaning materials and the proper procedure. You can simply remove rust and debris by merely using the cleaning tools that you already have at home.

The things that you will need are small bucket, hot water, wire brush, wire cup on the drill, dry rags, and WD-40.

Here are the steps in cleaning engine block:

  • Gather the necessary supplies for cleaning.
  • Get a small bucket and fill in ½ full of hot water. Make sure to attach your wire cup into the drill. The drill should be charged.
  • Scrub the engine block using a wire brush. Remove rust particles and debris with hot water and your wire brush. Immerse the brush into a bucket of hot water, shake to remove excess water and scrub the rusty surface.
  • Get a clean dry rag and wipe your engine block after scrubbing so that you can evaluate if the area still needs a thorough cleaning.
  • Remove rust from crannies and small nooks of the engine with your wire cup onto the drill. The wire cup helps remove rust from the engine’s crevices and small corners. Be very careful in cleaning as the wire cup can destroy the paint and the wiring. A wire cup can be utilized for non-reachable areas that can’t be accessed using a wire brush.
  • Wipe the entire engine block with your dry rag that has been moistened with hot water. Continue wiping and remove as much dirt as possible.
  • Keep the area dry with a dry rag to eliminate moist residue.
  • Apply WD-40 onto your engine block. Use a clean rag in working with your WD-40 to remove dirt particles.

Some people suggest using muriatic acid in removing rust onto the engine block. However, this chemical can damage the engine block if the solution is not properly rinsed. It can corrode the engine block causing further damage.
