Just to add to what dave said, the only limitation to how frequently you clean is the cost of the cleaning medium. You can wipe every board if you want to, but you'll go through material accordingly. If you're printing 16mil pitch or smaller, cleani

Of course there are solvents which are less harmful to the environment than others. The operative phrase is �less harmful�. As a rule, water-based chemistries are �greener� than solvents. There are some solvent blends designed for aqueous-based eq
