What Are Cleaning & Janitorial?
The Cleaning and Janitorial category covers cleaning products for electronics manufacturing and lab environments: isopropyl alcohol (IPA), flux removers, PCB cleaners, precision wipes, ultrasonic cleaning solutions, and compressed air dusters. Proper cleaning removes flux residue, contamination, and particles that can cause corrosion, leakage currents, and reliability failures. LCSC stocks 1,000+ cleaning SKUs.
Cleaning & Janitorial — Definition and Sub-Categories
Electronics cleaning involves removing contaminants — flux residue, solder balls, dust, fingerprint oils, and moisture — from printed circuit boards and components to ensure reliability and cosmetic quality.

How to Choose: Cleaning & Janitorial Selection Guide
For general PCB cleaning after soldering, 99%+ IPA is the standard — it dissolves flux residue, evaporates quickly, and leaves no residue. For stubborn water-soluble flux, use dedicated flux remover spray. For production-scale cleaning, ultrasonic baths with appropriate solution provide thorough cleaning of complex assemblies. Always verify material compatibility before using any solvent near plastic housings, labels, or coated components.

Frequently Asked Questions
Q: Do I need to clean no-clean flux?
No-clean flux residue is designed to be safe to leave on boards. However, cleaning is recommended in high-reliability applications (medical, aerospace), when applying conformal coating (residue affects adhesion), or when cosmetic appearance matters (visible residue on customer-facing products).
Q: What concentration IPA should I use?
99%+ IPA for electronics cleaning. Lower concentrations (70%, 91%) contain water that can leave residue or damage moisture-sensitive components. For critical cleaning, use 99.9% (reagent grade) IPA.
Q: How does ultrasonic cleaning work?
Ultrasonic cleaners generate high-frequency sound waves in a liquid bath, creating microscopic cavitation bubbles that implode on contact with surfaces. This mechanical action dislodges contaminants from complex geometries like under BGA packages and between fine-pitch component leads that manual cleaning can’t reach.
