Acidic foods, such as citrus juices, tomatoes, rhubarb, vinegar, alcohol or milk, should be wiped up and not allowed to bake onto the porcelain during the next use. • The heating elements in the oven do not require cleaning. The elements burn themselves clean when the oven is in use. When cleaning this appliance: • Use the mildest cleaning procedure that will do the job efficiently and effectively. Some cleaners of the same type are harsher than others. Try on a small inconspicuous area first. • Always rub metal finishes in the direction of the polish lines for maximum effectiveness and to avoid marring the surface. • Use only clean soft cloths, sponges, paper towels, fibrous brushes, plastic, non-metal or steel wool soap pads for cleaning and scouring, as recommended on the chart. • Most exterior parts of this appliance can be cleaned with hot sudsy water (except the various items specifically identified otherwise). When rinsing is required, rinse thoroughly. • Always wipe dry immediately to avoid water marks. • DO NOT USE CHLORINE BASED CLEANERS. Page. 87
