What kind of vinegar can I put in my washing machine?

When cleaning or freshening a residential washing machine, you should exclusively use plain, distilled white vinegar. Distilled white vinegar contains approximately five percent acetic acid, which provides the ideal mild acidity needed to dissolve mineral scale, break down soap scum, and neutralize mildew odors without leaving behind sticky residues or staining fabrics. You should strictly avoid dark kinds of vinegar like apple cider vinegar, red wine vinegar, or balsamic vinegar, as their natural sugars and color pigments will stain your clothes and leave a sticky, smelly residue inside the drum. You can troubleshoot cleaning agents easily. You can verify proper cleaning when running a hot cycle with distilled white vinegar leaves your washing machine sparkling clean and free of residue.
