As manufactured components become smaller, more intricate and more performance-critical, removing contamination is no longer a routine production step.
It is an essential part of product reliability.
A small amount of oil can interfere with coating adhesion. Silicone contamination can compromise bonding or finishing. Flux trapped beneath densely populated components may contribute to electrical reliability problems. Heavy grease left inside a tight cavity can affect movement, assembly or inspection.
For aerospace, automotive and electronics manufacturers, the question is no longer simply:
“What cleaner should we use?”
The more useful questions are:
Why Tough Residues Are Becoming More Difficult
Manufacturing processes are changing.
Aerospace assemblies increasingly combine lightweight metals, composites, high-performance polymers and sensitive electronics. Automotive manufacturers produce more sensors, cameras, electronic controls, battery components and precision fluid-management systems. Electronics assemblies are becoming denser, with smaller gaps and lower component standoff heights.
At the same time, manufacturers are introducing new lubricants, fluxes, adhesives, molding compounds, processing aids and protective coatings.
The residue is only one part of the challenge. Manufacturers must also consider:
That is why cleaning chemistry must be matched to the complete application.
Start by Identifying the Residue
Different residues have different chemical characteristics. Oils, greases, silicones, waxes, fingerprints and flux residues do not necessarily respond to the same cleaning fluid.
A cleaner selected for light oil may struggle with heavily polymerized grease. A fluid that removes one type of solder flux may not deliver the same result on another formulation. Silicone contamination may require a different cleaning approach than machining oil or particulate.
This is where the principle of “like cleans like” becomes important. The cleaning chemistry must have an affinity for the contaminant being removed while staying compatible with the materials being cleaned.
Before recommending a process, a MicroCare cleaning expert may consider:
Manual Cleaning for Targeted Applications
Manual cleaning can be an effective choice when contamination is localized, production volume is limited or a part requires cleaning during maintenance, repair, rework or inspection.
MicroCare cleaners and degreasers are available for removing contaminants such as grease, lubricants and fingerprints from machinery, manufactured parts and surfaces.
A manual cleaning process may be suitable for:
Fluid selection, application method, dwell time, agitation, wiping material and drying can all affect the final result. Applying more fluid is not always the answer. The goal is to use the correct fluid and technique to remove the contaminant efficiently and consistently.
Vapor Degreasing for Batch Cleaning
When manufacturers need to clean batches of parts efficiently, vapor degreasing can provide a fast and repeatable process.
Vapor degreasing uses specially engineered, low-boiling cleaning fluids that can wash contaminants from precision parts and then dry quickly. The process can help clean complex geometries because the fluid reaches small spaces, channels and difficult-to-access areas. MicroCare describes its precision vapor degreasing fluids as being designed to remove oils, greases and other contaminants from manufactured components while supporting solvent recovery and process efficiency.
Depending on the equipment and application, parts may be cleaned through combinations of immersion, vapor rinsing, spray-under-immersion, ultrasonics or other process steps.
Potential advantages include:
MicroCare Vapor Degreasing Fluid Examples
MicroCare offers several cleaning-fluid options for vapor degreasing applications. The correct choice depends on the contaminant, materials, equipment and process requirements.
Tergo™ Performance Fluids
Tergo Performance Fluids are proprietary MicroCare formulations developed for precision cleaning. They can remove contaminants such as fluxes, lubricants, dust, metal particulate, inks, fingerprints and waxes from electronics and other manufactured parts.
These fluids may be evaluated for applications involving:
Some residues require greater cleaning strength.
Tergo HDF is designed for challenging soils such as heavy hydrocarbons, greases, caramelized residues, waxes and silicone oils. MicroCare identifies applications across aerospace, automotive, medical, industrial and other precision manufacturing sectors.
It may be considered when lighter-duty fluid cannot adequately remove stubborn contamination, subject to testing for equipment, process and material compatibility.
MicroCare™ 72DE Engineered Fluid
MicroCare 72DE Engineered Fluid is designed for medium- to heavy-duty degreasing and flux removal. It can remove oils, greases, flux residues and particulate from compatible electronics and metal components.
MicroCare™ 73DE Engineered Fluid
MicroCare 73DE Engineered Fluid is designed for precision cleaning, vapor degreasing and lubricant-deposition applications. It can remove contaminants including oils, waxes, silicones, greases and certain flux residues from compatible components.
Each fluid has different performance, compatibility, safety and environmental characteristics. Product selection should therefore be based on the specific application rather than on cleaning strength alone.
Why Standard Products Are Often the Best Starting Point
Many tough cleaning problems can be solved using an existing MicroCare cleaner or vapor degreasing fluid.
Beginning with an established product can offer important advantages:
That may include a manual cleaner for targeted residue removal, a heavy-duty degreaser for maintenance applications or a Tergo vapor degreasing fluid for batch production.
When a standard product meets the requirements, there is no need to make the process more complicated.
When a Cleaning Challenge Requires More
Some applications do not fit neatly into a standard category.
A manufacturer may need to remove a proprietary lubricant from a combination of metal and polymer surfaces. An electronics assembly may hold several residue types and sensitive components. An aerospace part may have a difficult internal geometry and a strict cleanliness specification. A production process may require specific evaporation, solvency, drying or material-compatibility characteristics.
In these situations, MicroCare can help determine whether the answer involves:
Test Before You Scale
A fluid that looks promising on paper should be evaluated using the actual parts and contamination whenever possible.
The MicroCare Critical Cleaning Lab works with manufacturers to test cleaning fluids against representative parts, soils and process conditions. Testing can help assess cleaning performance, compatibility and process reliability before a solution is introduced into full production.
A cleaning evaluation may help answer questions such as:
Expertise Becomes More Important as Devices Become More Complex
Modern cleaning challenges rarely involve a single variable.
The strongest cleaning fluid is not automatically the best cleaning fluid. The fastest process is not always the most reliable. A cleaner that performs well on a metal test coupon may react differently when used on a finished assembly having plastics, coatings, labels, seals and sensitive electronics.
The right solution balances:
It is an essential part of product reliability.
A small amount of oil can interfere with coating adhesion. Silicone contamination can compromise bonding or finishing. Flux trapped beneath densely populated components may contribute to electrical reliability problems. Heavy grease left inside a tight cavity can affect movement, assembly or inspection.
For aerospace, automotive and electronics manufacturers, the question is no longer simply:
“What cleaner should we use?”
The more useful questions are:
- What exactly is the contaminant?
- What material is underneath it?
- How is the residue applied or created?
- Where is it found on the part?
- What level of cleanliness is required?
- What happens to the part after cleaning?
- Should the process be manual, automated or performed in a vapor degreaser?
- Can the cleaning chemistry be integrated into the existing production process?

- Cleanliness specifications
- The next production step
That is why cleaning chemistry must be matched to the complete application.

- Whether it has been heated, cured or polymerized
- The thickness and quantity of the contamination
- The component’s materials and coatings
- Required cleanliness standards
- Production speed and volume
- Available cleaning equipment
Manual Cleaning for Targeted Applications
Manual cleaning can be an effective choice when contamination is localized, production volume is limited or a part requires cleaning during maintenance, repair, rework or inspection.

A manual cleaning process may be suitable for:
- Localized grease or oil removal
- Maintenance and repair
- Cleaning before inspection
- Surface preparation
- Removing residues from accessible areas
- Low-volume or specialized production
- Cleaning parts that cannot be placed in automated equipment
Fluid selection, application method, dwell time, agitation, wiping material and drying can all affect the final result. Applying more fluid is not always the answer. The goal is to use the correct fluid and technique to remove the contaminant efficiently and consistently.

The MicroCare Critical Cleaning Lab works with manufacturers to test cleaning fluids against representative parts, soils and process conditions. Testing can help assess cleaning performance, compatibility and process reliability before a solution is introduced into full production.
A cleaning evaluation may help answer questions such as:
- Does the fluid remove the residue completely?
- How quickly does it work?
- Is agitation needed?
- Can it reach recessed areas?
- Does it affect plastics, elastomers, coatings or markings?
- Does the part dry without visible residue?
- Is the process repeatable?
- Can the fluid be used in the manufacturer’s equipment?
- Will the surface be ready for bonding, coating, plating or assembly?
