Shower – For a deep cleaning, fill a spray bottle with a mixture of citric acid and hot water. Use two tablespoons of citric acid to one liter of hot water. Shake the bottle and then spray the surfaces of the shower. For hard-to-remove stains, you can soak a paper towel in the mixture and lay it on top of the stain.

Citric Acid to Prevent Sugar Crystallizing:
I always prefer to add citric acid at the end when I am making my homemade jams. Adding citric acid prevents sugar crystallizing and helps to improve the flavor and the color of the jam that we are making. Try to add it at the end and add it according to sourness of the fruit you are making the jam with. You can also add it to sugar syrups, sherbets, etc.
