Cleaning by wiping with a soapy water solution will remove dust from cutting or prolonged storage. Residual soapy film may affect keying of inks or vinyls and should be removed using a lint free wipe moistened with aliphatic solvent - heptane or octane. These solvents will remove greasy deposits and dust or dirt adhering to the surface, as will methyl alcohol or methylated spirits.
Wipe in one direction only; wiping with a circular motion can create additional static charge. Abrasive and alkali cleaners will harm the surface finish and must not be used. Cleaners must not contain silicone compounds, as residues of these prevent vinyl inks adhering.

Static Electricity
Static electricity is produced when the protective film is stripped off and during processing and handling. It is necessary to remove it from panels which are to be screen printed. Static charges can be neutralised temporarily in several ways.
Isopropyl alcohol solution applied to the sheet surface by wipe or spray evaporates quickly in air, leaving an antistatic film which is effective for a considerable period of time. Wiping with soapy water solution has a charge neutralising effect.
The static charge can also be neutralised by blowing ionised air on to the panel or component. Foamalux AS uses a special formulation to resist the build up of static charge.

Tolerances
When processing eg. screen printing and tighter tolerances are required, the user, when ordering, must make allowances for truing panels to the accuracy required for processing.
