How to clean your stainless steel water bottle or coffee maker using Vinegar or Bleach

Use half bottle vinegar with half bottle water i.e., vinegar to water 1:1 ratio. Rinse it.

Avoid using bleach. If you have used bleach. Use half teaspoon for 1liter water. Rinse it twice.

(2 teaspoons per gallon (3.78 liters)=> 1 teaspoon for 1.8 liters) =>~1 litre.

 

Notes:

White vinegar has 5 percent acidity; while cleaning vinegar, on the other hand, has 6 percent. 
20 percent stronger than white vinegar.

Cleaning vinegar can be used undiluted or mixed with water, depending on the job.
For tough stains on fabric furniture or clothes, use cleaning vinegar alone on a sponge or rag to wipe away the spot. 

 It is not recommended to use cleaning vinegar—or white vinegar, for that matter—on natural stone, waxed wood, cast iron or aluminum.
