Preparing and Cleaning

Preparing Perspex

The surface protection film can be left in place during fabrication and all marking-out drawn on the film. However, it must be removed before thermoforming although in the case of extruded acrylic, the film may often be left in place provided sheets are only lightly formed and the film is in good condition. Any imperfections in the film can cause marks to be transferred to the thermoformed article. It is therefore, the customer’s responsibility to decide whether or not the film should be left in place.

Cleaning Perspex

Cleaning of Perspex® is not generally required until after fabrication. However, if a product is to be printed, it may sometimes be advisable to wash the surfaces to be printed with clean, fresh water using a chamois leather or soft cloth. This has the benefit of removing all traces of static charge from the sheet after removal of the film which might otherwise attract dust.

For all general purpose cleaning, Perspex® should be washed with clean, cold water to which a little detergent has been added. The use of any solvents such as methylated spirits, turpentine, white spirit or any proprietary window cleaning products is neither necessary nor recommended.

The ideal procedure is to polish every one to two weeks using a 100% cotton cloth.
