MG Chemicals 426-NS, Super Wick #4 Blue, Static Free, No Clean, 2.5mm, Case of 10
MG Chemicals 426-NS Super Wick #4 Blue — No-Clean Solder Desoldering Braid
MG Chemicals 426-NS is a no-clean solder wick made from tightly woven, oxide-free copper braid coated with a high-activation-temperature no-clean flux. The flux residue left after use is non-conductive and non-corrosive — no post-rework cleaning required. High purity copper and tight weave construction deliver fast wicking action, minimizing dwell time and reducing heat stress on sensitive PCB pads and components.
The 426-NS is the go-to choice for electronics assembly and rework benches where no-clean process compatibility is required — including surface mount rework, through-hole repair, and general PCB desoldering operations.

Key Features
- No-clean flux — residue is non-conductive and non-corrosive; no post-rework cleaning step required, saving time and reducing solvent use
- Static-free / ESD-safe bobbin — anti-static spool protects ESD-sensitive components during handling and use
- Fast-wicking action — tight copper braid weave and high-purity oxide-free copper maximize solder uptake speed and minimize dwell time
- 2.5mm width (#4 Blue) — ideal for standard SMT pads, through-hole leads, and general PCB rework; wide enough for efficient solder removal without bridging adjacent pads
- High activation temperature flux — activates at soldering temperatures for reliable wicking without premature flux burnout
- NSF listed — compliant with NSF Nonfood Compounds Program requirements
Ideal Applications
- PCB rework and repair in no-clean process environments
- Surface mount component removal and pad cleanup
- Through-hole solder removal and repair
- Benchtop electronics repair and service
- ESD-sensitive assembly environments
- Production rework lines requiring no post-clean process
Frequently Asked Questions
What does "no-clean" mean for solder wick?
No-clean means the flux coating on the braid leaves a residue that is non-conductive and non-corrosive after use. You do not need to clean the board after using 426-NS — the residue will not cause electrical leakage or corrosion over time. This is ideal for high-volume production environments where a cleaning step would add cost and cycle time.
What size pads is the #4 Blue (2.5mm) best for?
The 2.5mm width is the most versatile size for general PCB rework — suitable for standard SMT pads, IC leads, and through-hole components. For finer pitch work, consider the #2 Yellow (1.5mm, 424-NS) or #3 Green (2.0mm, 425-NS). For larger pads and connectors, the #5 Brown (3.0mm, 427) may be more efficient.
Is the 426-NS safe for ESD-sensitive components?
Yes — the 426-NS comes on an ESD-safe anti-static bobbin, making it safe to use in ESD-controlled environments. The bobbin itself will not generate static discharge that could damage sensitive components.
Do I need flux when using solder wick?
The 426-NS braid is pre-fluxed with no-clean flux, so additional flux is generally not required for standard rework. However, adding a small amount of additional no-clean flux to the pad before applying the wick can improve wicking speed on oxidized or difficult pads.
What is the difference between 426-NS and 426 (standard)?
The 426-NS uses a no-clean flux formulation, leaving residue that does not require cleaning. The standard 426 uses a rosin flux that may require cleaning with IPA or a flux remover after use, depending on your process requirements.
