With the use of modern trim materials it is important that proper cleaning techniques and cleaners can be used. Failure to do this on the first cleaning may result in water spots, spot rings, or setting of stains, all of which make it more difficult to remove on a second cleaning.

Dust and loose dirt that accumulate on interior fabrics should be removed often with a vacuum cleaner or soft brush.

Vinyl or leather trim should be wiped regularly with a clean damp cloth.

Normal trim soil, spots, or stains can be cleaned with conventional cleaners.

Use the following basic steps before cleaning:

  1. Remove stains as quickly as possible before they set.
  2. Use a clean cloth or sponge and change to a clean area often. A soft brush may be used if stains persist.
  3. Use solvent type cleaners only in a well ventilated area; also, do not saturate the stained area.
  4. If a ring forms after spot cleaning, clean the entire area immediately.
  5. Follow specific instructions on cleaner labels.

General Soilage or Water Spots on Fabric Trim

Multi-purpose powdered cleaner is for this type of cleaning and for cleaning panel sections where small cleaning rings may be left from spot cleaning.

    • Vacuum area thoroughly to remove loose dirt.
    • Always clean a full trim assembly or complete trim section. Mask surrounding trim along stitch or welt-lines.
    • Mix multi-purpose powdered cleaner in strict accordance with directions on the label container. Mix in proportion for smaller quantities.
    • Use suds only on a clean sponge or soft bristle brush. Do not saturate fabric or rub harshly with the brush.
    • Immediately after cleaning, wipe off excess cleaner with slightly damp absorbent towel or cloth.

Important: Immediately after wiping, force-dry fabric with an air hose, heat dryer or heat lamp. (Be careful with heat dryer or lamp to prevent damage to fabric.

When trim materials with a sheen or luster finish drying, wipe fabric lightly with a soft clean cloth to restore the sheen or luster.

Spot Cleaning Fabric with Solvent Cleaner

Before trying to remove a spot or stain from fabric, determine as accurately as you can what kind and how old the spot or stain is. Some spots or stains can be removed with water or mild soap solvent. See "Removal of Specific Stains, Grease or Oil Stains" next. Stains should always be removed as soon as possible.

Some types of stains or soilage, such as lipstick, inks and grease, are very difficult (sometimes impossible) to completely remove. When cleaning a type of stain or soilage be sure not to enlarge the soiled area. Fabric cleaner (solvent type) is excellent for spot cleaning grease, oil, or fat stains. Use the following instructions to spot clean fabric:

  1. Gently scrape excess stain off trim material with a clean, dull knife or scraper. Use very little cleaner, light pressure, and clean cloths (preferable cheese cloth).
  2. Clean from the outside of the stain "feathering" towards the center. Keep changing to a clean section of cloth.
  3. When the stain is cleaned from the fabric, immediately dry the area with an air hose, heat dryer or heat lamp. (Be careful with heat dryer or lamp to prevent damage to fabric).
  4. If a ring still forms, immediately repeat the cleaning operation over a slightly larger area with emphasis on "feathering" toward the center. If ring still remains, mask off surrounding trim sections with a multi-purpose powdered cleaner. See "General Soilage or Water Spots on Fabric Trim" previously.

Removal of Specific Stains, Grease, or Oil Stains

These include grease, oil, butter, margarine, shoe polish, coffee with cream, chewing gum, cosmetic creams, vegetable oils, wax crayon, tar, and asphalts.

    • Carefully scrape off excess stain; then use a fabric cleaner (solvent type) as previously described.
    • Shoe polish, wax crayons, tar, and asphalt will stain if allowed to remain on trim; they should be removed as soon as possible. Cleaner will dissolve them and may cause them to "bleed".

Non-Greasy Stains

These include catsup, coffee (black), egg, fruit juice, milk, soft drinks, wine, vomit, and blood.

  1. Carefully scrape off excess stain; then sponge stain with cool water.
  2. If stain remains, use a multi-purpose powdered cleaner (foam type) as previously described.
  3. If odor persists after cleaning vomit or urine, treat area with a water-baking soda solution: 0.3 cu·in/5 milliliters (1 teaspoon) baking soda of 15.3 cu·in/250 milliliters (1 cup) of warm water.
  4. If needed, clean lightly with fabric cleaner (solvent type).

Combination Stains

These include candy, ice cream, mayonnaise, chili sauce and unknown stains.

  1. Carefully scrape off excess stain; then clean with cool water and allow to dry.
  2. If stain remains, clean with fabric cleaner (solvent type).

Cleaning Vinyl or Leather Trim

Ordinary soilage can be removed from vinyl or leather with warm water and a mild soap such as saddle soap or oil soap or equivalent.

  1. Apply a small amount of soap solution and allow to soak for a few minutes to loosen dirt.
  2. Rub briskly with a clean, damp cloth to remove dirt and traces of soap. Repeat if necessary.
  3. Some compounds such as tar, asphalt, shoe polish, etc., will stain if allowed to remain on trim. They should be wiped off as quickly as possible and the area cleaned with a clean cloth dampened with vinyl cleaner (solvent type).
