Perhaps the best option for bulk citric acid

This citric acid is non-irradiated and can be used for cooking, cleaning and also storing cut up fruit while preventing the typical browning. It can be a preservative as well. So many uses and it’s natural which is my preference! This citric acid is obtained from a non-GMO corn source. I trust Frontier Co-op products, I’ve been using them for years!

Ideal spices

All the spices from Frontier Co-op have lived in my kitchen for over 7 years, and this citric acid is no exception. I use it both in drinks and around the house—for example, to descale my kettle or clean certain utensils.

great for cleaning stains in clothes

Citric acid can be effectively combined with vinegar to tackle tough stains, particularly those caused by hard water, limescale, and soap scum. This mixture is useful for cleaning surfaces like shower tiles, glass doors, mirrors, and faucets, where the combined acidity enhances cleaning power. While mixing citric acid and vinegar is safe and does not produce a harmful reaction, it is often unnecessary since citric acid is particularly effective on limescale on its own. also use for washing clothes by mixing this with Bicarb powder instead of using off the shelf toxic washing powders

Great for cleaning and cooking

we use this in the espresso machine to descale, clean stainless steel, keep cut fruit from browning, and more. Fantastic thing to have in the kitchen. It comes in a bag that doesn't reseal so I like to keep it in a jar for storage.
