Using Foam-Type Cleaner on Fabric Vacuum and brush the area to remove any loose dirt. Always clean a whole trim panel or section. Mask surrounding trim along stitch or welt lines. Mix Multi-Purpose Powdered Cleaner following the directions the on container label. Use suds only and apply with a clean sponge. Don't saturate the material. Don't rub it roughly. As soon as you've cleaned the section, use a sponge to remove the suds. Rinse the section with a clean, wet sponge. Wipe off what's left with a slightly damp paper towelor cloth. Then dry it immediately with a blow dryer or a heat lamp. NOTICE: Be careful. A blow dryer may scorch the fabric. Wipe with a clean cloth. Using Solvent-Type Cleaner on Fabric First, see if you have to use solvent-type cleaner at all. Some spots and stains will clean off better with just water and mild soap. If you need to use a solvent: Gently scrape excess soil from the trim material with a clean, dull knife or scraper. Use very little cleaner, light pressure and clean cloths (preferably cheesecloth). Cleaning should start at the outsideof the stain, "feathering" toward the center. Keep changing to a clean section of the cloth. When you clean a stain from fabric, immediately dry the area with a blow dryer to help prevent a cleaning ring. (See the previous NOTICE.) 6-49
