See page 13 for more instructions.
·
Keep the recommendations against scum (waxy buildup).
·
Use correct amount of detergent for load size, soil level,
and water hardness.
·
To restore discolored load of whites, use rust remover safe for
fabric.
·
Install nonprecipitating water softener or an iron filter in your
water supply system for an ongoing problem.
·
Before washing, run water for a few minutes to clear lines.
·
Wash lint-producing items, like flannel sheets, towels, and the like
separately from dark fabrics and fabrics that tend to collect lint.
