CLEANING AND MAINTENANCE 

 

Tools:  

McD Hi-Temp Grill Cleaner (HCS), McD All 

Purpose Super Concentrate (HCS), McD’s  NO-
SCRATCH

 Pad and Pad Holder, a suitable 

container, High-Temperature Pot Brush and Grill 
Cloth, Stainless Steel Pan Filled With Lukewarm 
Water, Protective Gloves, (to protect hands from heat), 
Grill Squeegee and Grill Scraper. 
 

Warning:  

The  upper platen surface and edges are 
very hot!  To prevent burn injuries, use 
extreme caution when wiping down release 
sheets and platen edges. 

 

Important: 

Frequently throughout the day, (at least 4 

times per hour), thoroughly wipe down the 
release sheets and  platen edges with a 
damp grill cloth. 

 
1.  Press the "MENU" button until "CLEAN MODE" is 

displayed, (the control will maintain the proper 
cleaning temperature).  Repeat with the other 
control.  "READY TO CLEAN" will be displayed and 
an audible alarm will sound when the grill is at the 
proper cleaning temperature.  Press the "MENU
button to display "OFF."  The "OFF" position on the 
controllers allows the operator to raise and lower 
the upper platens, (for clamshell grills), to alternate 
positions for proper cleaning of the platen edges. 

 
2. Empty and replace the grease troughs. Grease 

troughs should be emptied and replaced consistent 
with store security policy. 

 
3. Put on the protective gloves and wipe down the 

exposed surface of the release sheet with a damp 
grill cloth. 

 

4.  Remove the release sheet locking clips and bars. 

Clean the release sheets following the instructions 
provided by your local cleaning chemical supplier.  

 
5. Scrape only the lower grill surface with the grill 

scraper, and squeegee any residue into the grease 
troughs with the grill squeegee. 

 

Caution: 

Do not scrape or otherwise scratch the 
upper platens.  The use of metal scrapers, 
abrasive pads, or wire brushes will 
permanently damage the surface of the 
upper platens. 

 
6. Open one packet of McD Hi-Temp Grill Cleaner, 

(HCS), and empty the contents into a suitable 
container.  (One packet cleans a 3ft. grill). 

 
7. Firmly attach the McD NO-SCRATCH

 Pad to the 

pad holder. 

 
8.  Dip the NO-SCRATCH

 Pad into the grill cleaner. 

9.  Spread a light coating of grill cleaner over the 

entire platen surface, BACK, FRONT AND SIDE 
EDGES of both upper platens.  DO NOT SCRUB 
WHILE APPLYING THE PRODUCT. 

 

10.  After applying the grill cleaner, lightly scrub the 

platen surfaces, BACK, FRONT AND SIDE 
EDGES with the NO-SCRATCH

 Pad until all the 

soil has been liquefied by the grill cleaner. For 
stubborn soils, apply additional grill cleaner and 
lightly scrub.  DO NOT RINSE THE PLATENS AT 
THIS TIME. 

 
11. Starting at the back of the lower grill, spread a light 

coating of grill cleaner over the entire surface.  DO 
NOT SCRUB WHILE APPLYING THE PRODUCT. 

 
12. After applying the grill cleaner, lightly scrub the grill 

surface with the NO-SCRATCH

 Pad until all the 

soil has been liquefied. 

 
13.  For Clamshell Grills, rinse the upper platens with a 

dripping wet grill cloth.  RINSE PLATEN EDGE 
THOROUGHLY, THEN WIPE DOWN BACK 
EDGE OF PLATEN. 

 
14. Carefully pour small quantities of lukewarm water 

onto the grill while brushing the surface, 
backsplash, and bullnose with a LONGLIFE

 pot 

brush or equivalent high-temperature brush. 

 

Continue until the water no longer boils away and 
the grill remains wet.  Squeegee dry. 

 

Caution:  

Ice, cold water, or large quantities of water 
must never be applied to the grill plate or 
upper platen.  Severe damage to the grill 
will occur! 

 
15. Clean the release sheets as follows: 

 

A)   Place the sheets on the lower grill.  Scrub 

both  sides  of  the  sheets  with  the  same                    
McD NO-SCRATCH

 Pad used on the grill. 

 
Note:    It is generally not necessary to apply 

additional product to the NO-SCRATCH

 

Pad.  If the pad is not wet enough, rewet with 
a small amount of water, if no cleaner is left. 

 

B)  Rinse both sides of the sheets with a wet grill 

cloth. 

 

C)  Drape the clean sheet over the grill towel bar. 

 
16.  Rinse the lower grill by flooding the surface twice 

with lukewarm water.  Squeegee after each rinse.
