How do i clean the oil off my lunch box after just finishing eating my lunch, without utensil soap at my disposal ?
I would try a putting few drops of dishwashing soap on a paper towel, then put that in a Ziploc bag with your lunchbox.
One more idea that I got from cleaning cast iron skillets in my home. You're not supposed to use soap on a cast iron skillet because it can remove the seasoning. The recommended way to clean them is to use salt and water. From what I've seen a paste of salt with a few drops of water will do a pretty good job of removing excess oil from a cast iron skillet, it doesn't take off 100% though. It would probably also work for your lunchbox, it's kind of abrasive though and would encourage rust depending on the material the lunchbox is made of.
The only things other than soap or detergent that will remove oil during washing are extremely hot water (like genuinely boiling!) or alcohol. Neither of these is likely to be more available than dishwashing or hand soap when you're washing out your lunch box in the work or school lunch room.
You might explore whether you can get dish detergent in little packets (like the ones with condiments in them from fast food restaurants); you could bring these with you and be able to properly wash your lunch box and utensils each day.
- Paper towel - this will absorb oil 95%
- Flour - Spread flour inside lunch box and rub the flour around the surface. This is best solution as it absorbs most of the oil. Based on my experience, I would say 99%
To avoid spreading of oil within box surface - keep a aluminium foil (or worst case plastics sheet) inside surface of box before putting food. (This will make you transfer food in another substance, if you want to warm in a microwave. Don't put aluminium foil /plastic wrapper inside microwave and heat)
A pack of wet wipes or baby wipes followed by drying with a paper towel would be an effective way to clean your cutlery and lunchbox without access to traditional dish washing facilities.
i would usually clean my tiffen box using paper towel with little amount of water. We don't need soap to clean the oil.
