Cleaning

Immediately after use the platen should be cleaned; the most common method is to use a dilute detergent.
Solvents to the particular coating can be used.
Some users apply the coatings to self-adhesive plastic tape or film which has been laid on the platen. The temperature error due to the intervening layer is said to be about 0.1 °C. Cleaning is accomplished very quickly the method commends itself when the MFFT bar is used for production control.
Other users lay aluminium foil over the platen before testing. A few drops of glycerine placed between the foil and platen ensure good thermodynamic contact and allow the foil to be smoothed out evenly.

DO NOT USE ABRASIVES TO CLEAN THE TEST PLATE.
DO NOT USE CAUSTIC BASSED CLEANERS.
TEST ANY NEW CLEANING SUBSTANCES ON THE EDGE OF THE PLATE AWAY FROM THE TEST ZONE.
