MG GS Owner's Handbook Manual page 180

Seat belts should only be cleaned with warm soapy water.
Do not use any solvent to clean the seat belt. Do not
attempt to bleach or dye the seat belt, it may weaken the
seat belt. After cleaning, wipe with a cloth and allow to
dry. Do not allow the seat belt to fully retract before it is
completely dry. Keep seat belts clean and dry.
If there are contaminants accumulated in the retractor, the
retraction of the seat belt will be slow. Please use a clean
and dry cloth to remove any contaminants.
Replacing Seat Belts
Collision accidents may damage the seat belt
system. The seat belt system may not be
able to protect users after damage which may
result in serious injury or even death. After
an accident, seat belts should be checked and
replaced as needed immediately.
Seat belts should not require change after minor collisions,
however, some other parts of the seat belt system may
require attention. Please consult an MG Authorised
Repairer for advice.
