MG Chemicals 4050-1L, Safety Wash for Electronics, 33 oz., Bottle, Case of 6
MG Chemicals 4050-1L Safety Wash is a high-purity liquid electronics cleaner for removing oils, inks and flux residues from compatible electronic assemblies. Its blend of ethyl alcohol, isopropanol and ethyl acetate offers an alternative when IPA alone does not provide enough cleaning strength. This listing is supplied as a case of six 1 L bottles.
Best Uses / Applications
- Manual PCB cleaning during electronics assembly, maintenance and repair.
- Removing light grease, oils, ink and organic contamination from compatible surfaces.
- Cleaning flux residues where the formulation has been validated against the specific flux and assembly materials.
- Maintenance benches requiring a residue-free cleaner with a moderate evaporation rate.
Key Features
- High-purity alcohol and ethyl acetate solvent blend.
- Moderate evaporation rate and zero solvent residue, as reported by MG Chemicals.
- Manufacturer-described plastic-safe formulation; test the actual materials, markings and coatings before use.
- Liquid bottle format for controlled dispensing into an approved cleaning process.

Choosing a Cleaning Approach
| Approach | Selection considerations |
|---|---|
| 4050 Safety Wash | Alcohol/ethyl acetate blend for oils, inks and flux residues; useful when IPA alone is insufficient. |
| IPA alone | A different solvent approach; compare cleaning results on the actual contamination rather than assuming equivalent performance. |
| Application-specific flux remover | Evaluate when a specific flux is difficult to remove; qualify the cleaner against both residue and substrate. |
Use and Safety Considerations
The SDS classifies 4050 as highly flammable and as causing serious eye irritation. Keep it away from ignition sources, use appropriate ventilation and the protective equipment specified in the SDS, and follow your facility's approved handling procedure. De-energize equipment before cleaning and allow complete drying before returning it to service. The product name “Safety Wash” does not mean nonflammable.
Do not assume compatibility with every plastic, seal, adhesive, coating or component marking. Test a representative sample before production use. The manufacturer TDS includes consumer-product VOC dilution instructions for specified uses and jurisdictions. Review those instructions and the requirements applicable to your process rather than treating the undiluted cleaner as universally compliant.
Frequently Asked Questions
What does MG Chemicals 4050-1L clean?
It is an all-purpose electronics cleaner formulated to dissolve oils, inks and flux residues. Validate results with your specific contamination and assembly.
Is this one bottle or a case?
This MTE listing is for a case of six 1 L bottles. The manufacturer identifies each individual bottle as 4050-1L.
How does it differ from IPA alone?
4050 combines ethanol and isopropanol with ethyl acetate. It is an option when IPA alone does not provide enough solvency for the contamination being removed.
Is Safety Wash nonflammable?
No. The SDS identifies it as a highly flammable liquid and vapor. The TDS lists a 13°C flash point.
Is it safe on every plastic?
No universal compatibility claim should be assumed. MG Chemicals describes it as plastic safe, but users should test the actual plastic, markings, adhesives and coatings before use.
Does it leave residue?
The manufacturer reports zero solvent residue. Dissolved contamination still needs to be removed through an effective, validated cleaning process.
Can it remove every no-clean flux?
Do not assume it can. Flux chemistry and processing conditions vary; test it on the exact residue and use a qualified application-specific cleaner if needed.
Where can I find the technical and safety documents?
The current manufacturer documents hosted below provide physical properties, handling precautions and manufacturer dilution guidance.
