Oil stains of any kind are a problem for most fabrics, including fleece. Here are some suggestions for removing them:
1. Blot as much oil as possible as soon as the spill occurs, using paper towels. Don't rub, which could cause the oil to spread.
2. Apply powder to the stain and let it sit for 30 minutes. You can use baby powder, baking soda, talcum powder, or cornstarch. Sprinkle the powder over the oil and let it sit for 30 minutes to absorb as much oil as possible. Then shake the blanket, vacuum or use a spoon to scrape the oil and powder away. Repeat if you can still see the stain.
3. Next, rinse the stain with cool water, then apply a few drops of regular dish soap to the stain. Scrub the soap into the stain with a toothbrush, then rinse again with cool water. (Avoid using soaps with added moisturizers.)
4. Launder separately as usual in cold water with your usual laundry detergent. Remember, no fabric softeners -- they make fabrics less absorbent!
5. Line dry only -- DO NOT use your dryer until you're sure the stain is COMPLETELY gone! Placing ANY kind of oil-stained fabric in the dryer can cause combustion, so DON'T DO IT!!!
6. If the stain remains, repeat the above, or consult your local dry cleaner.
Oil of any kind on ANY kind of fabric can be tricky to remove, but your Blue Zoca blanket is an investment, so the time and effort you put into keeping it stain-free are well worth it!
