Dometic china toilets should be cleaned regularly for maximum sanitation and
operational efficiency. You can clean it just as you would a household toilet.
Do not use caustic chemicals, such as drain-opening types, as they will
damage the seals.
BOWL CLEANING: For stubborn stains, use SeaLand
®
Bowl and Seal Cleaner
(Fig. A). It’s manufactured especially for use with Dometic toilets. In certain
locations where water is hard, a build-up of lime may dull the toilet bowl finish.
Restore the shine with this SeaLand cleaner. If you cannot find it in your area,
contact Dometic for your nearest dealer. If this cleaner is not available, you can
also use Bar Keepers Friend
®
cleanser. It is not necessary to vigorously scrub
with either product. Please follow label instructions.
SEAL CLEANING: After an extended time, mineral deposits from hard water can
build up under the edge of the rubber bowl seal, resulting in a slow leakdown of
water from the bowl. To prevent this mineral build-up, periodically clean under the
bowl seal with SeaLand Bowl and Seal Cleaner (Fig. B).
1. Shut off water supply and power to vacuum pump or vacuum generator.
2. Apply cleanser onto a cleaning brush, open the flush ball by pressing on flush
lever, and scrub under the seal. Make sure to push brush bristles between
bottom of seal and top of flush ball surface to scrub all parts of seal that come
into contact with flush ball.
3. Close ball and wait 2-3 minutes.
4. Open flush ball. Use brush and water to rinse away cleanser and loosened deposits.
5. After cleaning, turn on water and electrical power to toilet system.
