How Long Does a Can of MicroCare Solvent Last?
|
A.
|
FAQ 19 -- Unopened cans or cans connected to a Trigger Grip™ dispenser will last for years without degrading (see FAQ: "Shelf Life"). If you're asking how much cleaning a can will do, the typical can of PowerClean™ lasts 5-8 days in a busy rework environment. Slower-drying solvents will last even longer.
