Mart Washers, my introduction into Well Made Parts Washers

May 12, 2025 | Matt Reed

MART washers (from MART Corporation) are well-known in the industrial parts washing world, particularly for Cabinet Spray washers. Their systems are designed for heavy-duty cleaning, especially for industries like:

  • Engine remanufacturing

  • Heavy equipment maintenance

  • Railroad and aviation

  • Military and defense

  • Diesel rebuilders

  • Gear Box Repair

🔧 Key Features of MART Washers

1. Powerful Agitation Cleaning

MART pioneered what they call Power Flush cleaning, which uses high-flow, high-volume jets to clean parts through immersion and aggressive agitation. This is more effective than traditional spray washers for heavy grease, carbon, and baked-on debris.

2. Batch or Cabinet-Style Washers

They are typically front-loading cabinet where parts are placed in on table, baskets, or on fixtures. Known for their retractable turntable and oscillating manifolds. 

3. Water-Based Detergents

MART machines use aqueous cleaning solutions, not solvents, so they’re more environmentally friendly while still being tough on contaminants.

4. Built for Big, Dirty Jobs

These washers are built like tanks—very durable and capable of handling engines, transmissions, axles, and heavy castings.

Pros

  • Extremely effective for the largest, dirtiest parts. 

  • Environmentally safer than solvent washers

  • Long-lasting, American-made machines

  • Lower labor needs vs. manual cleaning

  • Can be refurbished and resold with good value retention

Cons

  • Large footprint – not ideal for small shops

  • Not as precise as ultrasonic or vacuum degreasers for fine parts

  • Higher upfront cost than basic spray washers

  • Water-based systems may require regular maintenance (filters, sludge removal)

🏁 Typical Users

  • Engine remanufacturers (Cummins, CAT rebuilders)

  • Heavy truck or diesel shops

  • Military base maintenance operations

  • Municipal or DOT garages

If you’re looking at the parts washer industry from a resale, appraising, or usage angle, MART washers are valuable and respected—especially in reman and diesel-heavy applications. Many shops look for used MART units because of their durability and lower cost compared to new.

Are you looking to sell, appraise, or buy a MART washer? Or are you comparing it to something like a solvent-based or vacuum unit?
