General
• As buns are toasted, they leave an oily residue buildup on the
conveyor belt and Teflon release sheet.
• Over a period of time, the residue will form a slick coating where
buns make contact on the belt surface.
• If this slick coating is not removed, the belt may not pull the buns
into the toaster or will not pull the buns completely through the
toaster, and the buns will burn.

Place the release sheet on a flat surface. Clean the release sheet with
a mild dishwashing detergent (CAPITAL used to clean trays works
well). Sanitize the surface by wiping it
with a cloth damp with tray sanitizing
liquid (Kay-5 Sanitizer).
The Teflon sheet uses both sides as the contact surface. When re-
installing, rotate the usage by turning top-to-bottom and/or turning the
sheet inside/out.
Residue on the belt is easy
to remove if it is still oily. If
the residue has formed a
slick coating, additional
scrubbing effort is required
to remove it.
The conveyor belt has only one contact surface and must be
re-installed with orange side facing out.
Place the belt (orange surface up) on a flat surface. Clean the
belt orange surface with a mild dishwashing detergent (CAPITAL
used to clean trays works well. Mix 1 part CAPITAL to 9 parts
water). Spray detergent onto orange portion of belt, then wait
1 minute for residue to dissolve. Spray detergent onto a
no-scratch pad and wipe the belt to remove residue. When the
belt is clean, the surface will have a tacky grip when you rub a
finger over the surface. Sanitize the surface by wiping it with a
cloth damp with tray sanitizing liquid (Kay-5 Sanitizer).
