Spot Cleaning Instructions for GreenShield® Treated Fabrics
The best time to deal with any spill is immediately. Because of GreenShield’s water and oil repellant properties, most spills on a GreenShield® treated fabric will be sitting on top of the fabric. Immediate gentle blotting of a simple liquid spill such as coffee or wine with a clean, absorbent cloth or paper towel will often completely remove the spill. If there are solids in the spill (mustard, tomato sauce, etc.), it is best to remove the solids with something like a spoon before blotting the spill. Do not rub at the spill since that may push it into the treated fabrics or make it bigger. If the spill is large, remember to blot toward the center so that you do not spread it. If the spill is not completely removed by blotting, the application of a fluid may be necessary. Before selecting a cleaning system, be sure to check the manufacturer’s instructions for the fabric and do not use cleaning materials which may damage the fabric itself.
The GreenShield® protective finish treated fabrics itself is generally not removed by treatment with spot stain removers. The GreenShield finish may be used with either water or solvent based cleaners. However, it is the fabric itself that determines which types of treatments are useful. The makers of GreenShield strongly recommend cleaning solutions with minimal environmental impact.
Lightly wetting the surface of the fabric with water and repeated blotting will pick up the remnants of many spills. Blotting the surface of a spill with a dilute solution of liquid detergent in cool water followed by blotting with a dry absorbent cloth will pick up slightly more stubborn stains. Hot water may set the stain and is not recommended. Rubbing gently with a cloth or a soft brush can be useful but hard brushing may alter the texture of some fabrics and therefore is not recommended. Removing more difficult stains and stains that have dried will require more effort. First, brush or vacuum off any dried component of the spill (mustard, betadine, etc.). Then, lay a damp cloth flat on the stain and blot with gentle pressure. If part of the stain is removed, repeat until removal is complete. If complete removal is not achieved, the same procedure can be used with a dilute, mild detergent. Following are a few examples of stain removal processes for a few selected spills.
Mustard spills on GreenShield treated fabrics will dry into beads or strands which will separate from the fabric and are removed simply by brushing the fabric or picking them up. A very small residue is removed by blotting with a damp cloth followed by drying with an absorbent towel.
Coffee spills on a GreenShield fabric will dry into small concentrated brown specks. Repeated blotting with a damp cloth picks up the spots and the area dried with an absorbent towel.
Betadine spills on a GreenShield fabric will dry into small concentrated reddish brown spots. The “plastic-like” spots sit on top of the fabric and can be removed by picking at the edge and lifting them off. Alternate blotting with wet and dry towels may remove the small residue remaining entirely or treatment with a dilute solution of a low residue detergent may be needed. (If the physical residue is not removed, the spots can be removed with prolonged blotting using the detergent solution.)
Italian Dressing spills on a GreenShield fabric will dry into a soft pasty residue that can rolled off of the fabric and picked up leaving a small residue on the top of the fabric. The surface may be gently blotted with a dry piece of paper towel followed by blotting with a dilute solution of detergent. The spotted area can be blotted with a damp cloth and then dried by pressing on a towel.
If these simple methods fail, it will be necessary to select a cleaning solution that is appropriate for the fabric and the composition of the stain. Many different types of spot cleaning solutions are available and can be purchased or formulated at home. A particular cleaner may be vastly superior for a particular stain or a sequence of treatments may be best, but mixing components is not recommended. (Chlorine bleaches should NOT be used with either ammonia or vinegar.)
Apply the selected cleaning solution directly to the stain as recommended by its manufacturer. Do not over wet. Allow the wetted fabric to sit for a time and then blot with a clean white cloth or paper towel. Repeat as needed. Depending on the cleaner’s instructions, a final water rinse may be recommended. Finally, dry the treated area by placing a weighted white towel on top of it.
It is impossible to evaluate all available cleaners but a number have been tested for both spot removal and their impact on the GreenShield treatment. Water-based spot cleaners that have been found to be compatible with fabrics using GreenShield fabric finish include:
- Woolite® uphoslstry cleaner
- Woolite® Oxy Deep®
- Resolve® Multi-Fabric
- Shout® Advanced
- Once’n Done®
Few solvent based spot cleaners have been evaluated with GreenShield. Solvent cleaners based on hydrotreated aliphatic hydrocarbons (such as Solv-a-clene™ and Goo Gone®) were compatible with GreenShield as was isopropyl alcohol (rubbing alcohol).
