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.
