Manual cleaning using isopropyl alcohol (IPA) works well. Flux Type Storage and Handling Procedures AMTECH Tacky Paste Flux Type Class Refrigerated storage at 4247F will prolong Tacky Paste Fluxs SynTECH-TPF N/C ROLO shelf life to no less than 1 year. Syringes & cartridges should be SynTECH-LF-TPF N/C for LF ROLO stored vertically with the dispensing tip down. Tacky Paste Flux should be allowed to reach ambient temperature naturally, NC-559-TPF N/C ROLO prior to use (about 6-8 hours).
