If you've got some greasy, difficult stains on your clothing, it turns out Coca-Cola might be able to solve the problem. Clever list site Listverse suggests that adding a little to your wash will make the difference:
Grease stains are famously difficult to remove from clothing and stain removers can be very expensive. Here is a cheap solution: empty a can of coke into your wash along with the usual detergent and run it through a normal cycle. This is also quite effective for removing blood and it helps to deodorise smelly clothes.
The reason it can break up stains is thanks to the carbonic and phosphoric acid inside. Most people hear about this ingredient and wonder how Coca Cola is safe to drink, but as Snopes details the amounts inside are too small to have any impact on your tough stomach — just your dirty laundry. While you might not want to drink a ton of Coca Cola thanks to the (real or artificial) sugar and sodium content, you and your soon-to-be clean clothes will be just fine.
