Cleaners & Degreasers
Industrial cleaners and degreasers remove oils, greases, flux residues, waxes, particulates, and other process contaminants from parts and surfaces prior to coating, assembly, inspection, or further processing. Formulation chemistry ranges from solvent-based systems, which dissolve soils directly into the cleaning fluid, to water-based (aqueous) systems, which rely on surfactants and detergency to lift and suspend contaminants, to specialized formulations engineered for specific soil types, substrate sensitivities, or regulatory requirements.
The right chemistry depends on the soil being removed, the substrate's material compatibility, the cleaning equipment available (wipe, spray, immersion, ultrasonic, or vapor degreasing), required cleanliness level, drying time, flash point and worker safety considerations, and applicable environmental and VOC regulations. Solvent-based cleaners generally offer fast evaporation and strong soil-dissolving power for oils and greases. Water-based cleaners avoid flammable solvents and often lower VOC content, but typically require a drying step and more attention to rinse water treatment. Specialized formulations, including bio-based, semi-aqueous, and precision electronic-grade cleaners, address applications where standard solvent or aqueous chemistry falls short.

Frequently Asked Questions
Frequently Asked Questions about Cleaners & Degreasers
What is the difference between a solvent-based and a water-based cleaner?
Solvent-based cleaners dissolve oils, greases, and waxes directly into the cleaning fluid, typically evaporate quickly, and don't require a separate drying step. Water-based cleaners rely on surfactants and detergency to lift and emulsify contaminants into an aqueous solution, and generally avoid the flammability and VOC concerns of solvents, but require rinsing and drying and more attention to wastewater treatment. The right choice depends on the soil type, substrate, available equipment, and applicable environmental regulations.
How is material compatibility checked before using a cleaner on a substrate?
Both solvent- and water-based cleaners can attack certain plastics, elastomers, coatings, or metals if not formulated or selected correctly, causing swelling, cracking, discoloration, or corrosion. Compatibility should be verified against the specific substrate, including any coatings, adhesives, or markings present, ideally with a small-scale test before full production use, rather than assumed from general chemistry class alone.
Why does flash point matter when selecting a solvent-based cleaner?
Flash point is the lowest temperature at which a solvent's vapors can ignite in air, and it directly affects storage, handling, and ventilation requirements. Low flash point solvents require stricter fire safety controls, spark-free equipment, and explosion-proof ventilation, while higher flash point or non-flammable formulations can simplify handling in some environments. Flash point should always be checked against the specific product's safety data sheet and matched to the facility's fire safety classification.
What does VOC content mean for a cleaner or degreaser?
Volatile organic compounds (VOCs) are carbon-based chemicals that evaporate readily and can contribute to air quality regulations and permitting requirements in many regions. Many solvent-based cleaners contain VOCs, while water-based and some specialized low-VOC or VOC-exempt formulations are designed to reduce this impact. Applicable VOC limits vary by jurisdiction, so local regulatory requirements should be checked against the specific product's VOC content.
What is vapor degreasing, and when is it used?
Vapor degreasing uses a heated solvent's vapor phase to condense on a cooler part, dissolve surface soils, and drain away clean, leaving the part dry with no rinsing step. It's commonly used for precision parts, complex geometries, and applications requiring tight residue and cleanliness specifications, and generally requires a solvent formulated and rated for vapor degreasing equipment rather than general wipe or spray use.
What makes a cleaner suitable for electronics applications?
Electronics cleaning generally requires low or non-conductive residue after evaporation, compatibility with sensitive components and circuit board materials, and controlled evaporation characteristics to avoid leaving streaking or film. Specialized precision-cleaning formulations are typically developed and tested for these requirements, and a general-purpose degreaser shouldn't be assumed suitable for electronics use without checking the product's specific residue and compatibility data.
What are bio-based cleaning solvents, and how do they differ from petroleum solvents?
Bio-based cleaning solvents are derived from renewable feedstocks, such as terpenes, citrus extracts, or soy and other plant esters, rather than petroleum. They can offer strong solvency for oils and greases with a different toxicity, odor, and biodegradability profile than traditional petroleum or chlorinated solvents, though flash point, evaporation rate, and material compatibility still vary by specific formulation and should be checked independently.
Why does drying time matter when choosing a cleaner?
Drying time affects production throughput, the risk of flash rusting on bare metal, and whether residual moisture or solvent could interfere with a downstream process like coating, bonding, or soldering. Fast-evaporating solvent cleaners often minimize drying time, while water-based cleaners typically require forced-air drying or longer ambient drying to avoid leaving moisture that can cause corrosion or contaminate the next process step.

Cleaner & Degreaser Chemistry Overview
Industrial cleaners and degreasers remove oils, greases, flux residues, waxes, particulates, and other process contaminants from parts and surfaces prior to coating, assembly, inspection, or further processing. Formulation chemistry generally falls into three families: solvent-based, water-based, and specialized formulations engineered for specific soil types, substrates, or regulatory requirements.
Solvent-Based
Dissolves oils, greases, and waxes directly into the cleaning fluid. Generally fast-evaporating with no rinse step required, but flammability, flash point, and VOC content need careful handling and regulatory attention.
Water-Based
Uses surfactants and detergency to lift and emulsify contaminants into an aqueous solution. Avoids solvent flammability and often lowers VOC content, but requires rinsing, drying, and wastewater management.
Specialized Formulas
Bio-based, semi-aqueous, and precision-grade cleaners engineered for specific soils, sensitive substrates, or applications where standard solvent or aqueous chemistry falls short.
Solvent-Based Cleaner Chemistries
Hydrocarbon Solvents
Petroleum-derived aliphatic or aromatic solvents offering good general soil removal at moderate cost, with flammability and VOC content that vary by specific blend.
Chlorinated & Brominated Solvents
Strong solvency and often non-flammable, historically common in vapor degreasing. Subject to increasing regulatory restriction in many regions, so current approval status should be checked before specifying.
Fluorinated Solvents
Low surface tension and good material compatibility, often used for precision and electronics cleaning where residue and substrate sensitivity are critical.
Bio-Based Solvents
Derived from renewable feedstocks such as terpenes or plant esters, offering an alternative toxicity, odor, and biodegradability profile to petroleum or chlorinated solvents.
Water-Based Cleaner Chemistries
Alkaline Cleaners
High-pH formulations effective on heavy oils, buffing compounds, and shop soils on robust metal substrates, often used in immersion or spray washers.
Neutral & Mild Cleaners
Near-neutral pH formulations selected for sensitive substrates, such as aluminum or coated parts, where alkaline chemistry risks etching or discoloration.
Surfactant/Detergent Systems
Rely on surfactant chemistry to emulsify oils and suspend particulates, with formulation tailored to soil type, water hardness, and rinse requirements.
Specialized Cleaning Formulations
Semi-Aqueous Cleaners
Combine solvent soil-dissolving power with a water rinse step, offering strong cleaning performance without full solvent immersion or full aqueous processing.
Precision & Electronics-Grade Cleaners
Formulated for low or non-conductive residue, controlled evaporation, and compatibility with sensitive components and circuit board materials.
Vapor Degreasing Fluids
Formulated and rated specifically for vapor degreasing equipment, condensing on parts to dissolve soils and draining away clean without a separate drying step.
