Could you use lemon juice as a preservative, as you use it in canning to kill bacteria.
To Sirima: I have given the idea of preserving your spray starch some thought. I have a few ideas that will probably work, but I have not tested any of them. If any of you do, please post your results on here for our benefit. Spray starch is great food for yeasts and bacteria, so I'm not surprised it spoils quickly. We need to identify preservatives that are fabric safe, inexpensive, relatively easy to purchase, and effective.
1. Grapefruit seed extract (GSE). Notice I said grapeFRUIT. Don't mistake this for grape seed extract. This is available at health food stores, about $10 a bottle that will last you a long time. You would want to use about 5-8 drops per quart of solution. You could use up to 12, I believe. It is acidic, and you don't want your starch to be too acid, or it will reduce the stiffness of the starch, and acid could hurt your clothes over time. But 7 drops of GSE will work safely. It has no odor or color. GSE is a strong natural antibacterial, and it's used in many natural body-care and home cleaning products. I think it's the best of my ideas here.
2. Essential oil of lavender. Lavender is antiseptic, but I don't know how much to use. The fragrance will transfer to your clothes. Some may like this, and some may not. I think I'd start with 6 drops. This is a rather pricey solution, as lavender is about $1 per ml.
3. Tea Tree Oil (TT). It is antiseptic, but some may find the fragrance of TT unacceptable for use in clothing. I'd use about 1/2 tsp per bottle of starch.
4. Silver. My suggestion here would be to drop in a clean genuine silver coin or piece of jewelry into your starch bottle. Silver is antibacterial. In the old days, people stored food in silver because it retarded spoilage.
You will have to test these ideas and see how long they preserve the starch solutions. Best wishes.
I used the recipe by Pat Sym it work very well, highly appreciated if any one can tell me how to keep the liquid ironing starch last long. Thank you
# 1 tablespoon cornstarch
# 1/2 cup water
1 Mix the cornstarch and the water in a saucepan over medium heat (not boiling) until mixture is smooth and transparent.
2.Let it cool enough so you can safely pour it into a spray bottle.
4.You're ready to go!
Spray your running shoes (or any sneakers) with spray starch. It protects them.
I once saw a tip to make spray starch to use when ironing. I can't find it. Does anyone know how? Julia
