Board Care & Cleaning Instructions

LCS MARKERBOARDS
NORMAL CARE

     Porcelain Enamel Steel Markerboards (LCS) may be washed as often as required. Porcelain is a form of glass; therefore, the surface should be cleaned similar to cleaning windows. 

     We recommend using clean water, Claridge 683 Board Cleaner or an ammoniated cleaner such as Windex®.  NOTE: Board Cleaner may damage lacquer finish on wood framed boards. Avoid direct contact with wood.

     The best method for cleaning is to use water or liquid cleaner, rub briskly, and then wipe the surface dry with a soft cotton cloth.  (Be sure to remove excess liquid from the chalktray.)  NOTE:  Do not use abrasive cleansers on LCS or MLC markerboard surface as they may dull or scratch the surface. (MLC is a markerboard surface painted on hardboard.) Permanent markers will stain the surface of MLC.  Low-odor markers tend to erase with more difficulty and may require more frequent cleaning of both MLC and LCS. Discontinue use of erasers saturated with marker residue build-up. 

STUBBORN STAINS

     Permanent markers, marker residue, lipstick, fingernail polish, etc. can be removed from the LCS markerboard writing surface with isopropyl alcohol without damaging the surface.  Merely clean, rinse well with clear water and allow to dry completely. NOTE:  MLC markerboards may be cleaned the same as LCS, except do not use solvents or abrasive cleansers on MLC surface.

INITIAL CARE

     Wash prior to initial use to remove any grime that may have settled on the surface.

 

VITRACITE CHALKBOARDS
NORMAL CARE

     Porcelain Enamel Steel Chalkboards (Vitracite) do not require regular washings and should not be washed daily.  Note:  Do not use aerosol spray-type chalkboard cleaners on Vitracite chalkboards.

     The Vitracite chalkboard surface may write and erase more efficiently after a “chalking-in process.”  This “chalking-in” process is quite simple and requires little time and effort.  First, make certain the chalkboard surface is completely dry.  Then, using the flat side of a pure white, good grade dustless chalk, chalk the entire surface.  With an all felt eraser, using a circular motion, work the chalk into the board surface. Last, clean the board with a good quality dry chamois or soft cotton cloth.  A faint “chalked-in” look is normal for a properly cleaned chalkboard surface.

STUBBORN STAINS

     Persistent buildup on Vitracite chalkboard surface may be removed with ordinary kitchen cleanser such as Ajax® or Comet®, flushed thoroughly with water, and dried per instructions above.  (Do not use abrasive cleanser on LCS or MLC markerboard surface.) NOTE:  We do not recommend the use of colored chalk.  Most colored chalk is petroleum based and may leave a film on the board surface.

 INITIAL CARE

     Wash prior to initial use to remove any grime that may have settled on the surface.
