Apple cider vinegar (ACV) is a fermented liquid produced from apple juice. A two-step process involving yeast and bacteria converts apple sugars into acetic acid, which is responsible for its characteristic tang and primary properties. ACV has been used as a household remedy for thousands of years. Today, many people explore its use in various washing routines for personal care and home maintenance.
Essential Preparations and Safety Guidelines
The high acidity of raw ACV (pH 2-3) means it must never be applied directly to the skin or hair without dilution. The acetic acid concentration (around 5%) is strong enough to cause irritation or chemical burns if used undiluted. Proper dilution is essential to mitigate this risk.
For general skin and hair use, start with a ratio of one part ACV to three or four parts water. Sensitive skin requires a weaker solution, such as one part ACV to five or six parts water.
Always perform a patch test before applying any new ACV solution to a large area of skin or the scalp. Apply a small amount of the diluted mixture to a discreet area, such as the inner forearm. Wait 24 to 48 hours and check for adverse reactions like redness, itching, or swelling before proceeding with broader use.
Applying ACV to Skin and Hair
Hair Rinse
The mild acid content in diluted ACV makes it a popular hair rinse. Its slightly acidic nature helps smooth the hair cuticle, increasing shine and reducing frizz. ACV can help restore the hair’s naturally acidic pH, which alkaline shampoos may disrupt.
To use as a clarifying rinse, mix two to four tablespoons of ACV with about 16 ounces of water. After shampooing, pour the mixture over the hair and scalp, letting it sit for a minute before rinsing thoroughly. This application helps address product buildup and offers mild antimicrobial properties for scalp health.
Skin Toner
A diluted ACV mixture can function as a skin toner, gently exfoliating the skin and potentially rebalancing its surface pH. A common ratio is one part ACV to four parts water, applied gently with a cotton pad while avoiding the eye area. Application should be limited to a few times a week. Overuse can strip the skin and lead to dryness.
Foot Soaks
ACV is also incorporated into foot soaks to manage odor and address bacterial or fungal overgrowth. A typical soak involves diluting one part ACV to two parts warm water, soaking feet for 15 to 20 minutes. The resulting acidic environment helps neutralize odor-causing bacteria that thrive in moist conditions.
Using ACV for Home Cleaning
All-Purpose Cleaning
The acetic acid in ACV provides natural cleaning capabilities for many household surfaces. This acidity effectively breaks down alkaline residues, such as mineral deposits from hard water and soap scum. An all-purpose cleaner is made by combining equal parts ACV and water in a spray bottle.
This diluted solution cleans countertops, toilets, and stovetop grime. For tougher spots like mildew, undiluted ACV can be applied and allowed to sit for 30 minutes before scrubbing. ACV cleaner is a biodegradable alternative to many commercial products.
Laundry Use
ACV is sometimes used in laundry as a natural fabric softener and odor neutralizer. Adding a small amount to the rinse cycle helps remove residual detergent and softens fabrics. While the acid eliminates lingering smells, ACV may stain certain fabrics and could potentially damage the rubber seals in some washing machines over time.
Surface Compatibility Cautions
Significant caution must be exercised regarding surface compatibility due to the vinegar’s acidic nature. ACV should not be used on surfaces where the acetic acid can cause etching or corrosion.
Surfaces to avoid include:
- Natural stone surfaces, such as granite, marble, or limestone, which can be etched, leading to permanent dullness.
- Unsealed grout.
- Cast iron and aluminum, as the acid can corrode these metals.
- Certain types of wood, as the acid can damage finishes.
