MIL-PRF-85570 Standard

What is MIL-PRF-85570?

MIL-PRF-85570 is a U.S. Department of Defense performance specification that defines the requirements for cleaning agents used on aircraft surfaces. It ensures effective cleaning while maintaining the integrity of display paint, camouflage coatings, and other sensitive finishes.

Key Features of the MIL-PRF-85570 Standard

Well-Defined Cleaning Categories

The standard covers multiple cleaning types, including:

• Type I – Diluted aromatic solvent

• Type IA – Aerosol form

• Type IW – Pre-moistened wipes

• Type II – Solvent-free cleaning solution

• Type III – Heavy-duty stain remover

• Type IV – Rubber cleaner

• Type V – Gel formula for wheel and landing gear areas

Versatile Dilution and Application Guidelines

Each cleaning type includes clear instructions for preparation and use, tailored to the degree of soiling. For example, Type II solutions may be diluted at a ratio of 1:14 for light dirt or 1:4 for heavy contamination, with specific usage directions for aerosol sprays or wet wipes.

Rigorous Testing Standards

Products must meet strict performance criteria—providing excellent cleaning power without corroding metals such as aluminum, steel, or alloys. They must maintain a stable pH, be paint-safe, prevent corrosion, and be compatible with a variety of industrial equipment.

Top Products Compliant with MIL-PRF-85570

TOP	Product Name	Product photo	Product Description
1	Krytox GPL 224		Krytox GPL 224 contains anti-corrosion/anti-wear inhibitors and is ideal for corrosive environments.
2	Krytox GPL 216		Krytox GPL 216 grease is a high performance grease that uses PFPE oil, PTFE thickener and molybdenum disulfide as an extreme pressure additive.
3	Krytox GPL 210		Krytox GPL 210 has high load carrying capacity and good lubrication properties under boundary and mixed friction conditions.

Applications of the MIL-PRF-85570 Standard

Aircraft Surface Cleaning

Ideal for removing oil, grease, carbon deposits, and general grime from surfaces such as fuselages, cockpit interiors, and wheel wells before inspection, maintenance, or repainting.

Safe and Environmentally Responsible

Compliant cleaners are biodegradable, non-toxic, and residue-free. They are compatible with hard water and designed to support safe, efficient, and sustainable maintenance operations.

Broad Use and Application Flexibility

These cleaners can be applied via spraying, wiping, scrubbing, rinsing, or in gel and wipe form, making them suitable for both on-airfield servicing and in-hangar maintenance work.
