Know how long you can safely store water in a matka before it becomes dangerous for consumption

A content creator recently shared a few helpful tips for those planning to use a matka: soak the pot in water for one full day before use, scrub and dry it thoroughly in the sun, and clean it daily while avoiding stagnant water for more than 2–4 days. 

But is this enough? And how long is too long to store water in it before it becomes unsafe? An expert explains what needs to be done to ensure your drinking water remains safe.

Is soaking and sun-drying a new matka enough to disinfect it before use?

Kanikka Malhotra, consultant dietician and certified diabetes educator at Health Pepper, tells indianexpress.com, “When you first bring home a new matka, soaking it and letting it dry in the sun are great first steps — soaking helps close any tiny pores in the clay, and sunlight can naturally help kill some bacteria. However, honestly, these steps alone aren’t always enough to ensure your matka is completely safe and bacteria-free.” 

She adds, “Give the matka a good scrub with coarse salt or baking soda for regular cleaning and disinfection of your matka. Use hot water and a brush for thorough cleaning, and avoid soaps or detergents that can be absorbed by the clay. You can use a little lemon juice before its first use. Rinse it well, and let it dry completely in the sun. Avoid strong soaps or chemicals, since clay can absorb them and taint your water.” 

If you’re really worried about bacteria, she suggests, you can use a mild vinegar solution (rinse thoroughly afterward).

How often should a matka be cleaned?

Malhotra mentions, “I recommend giving your matka a quick rinse with fresh water every time you change the water — ideally every day, especially in warm weather. This simple habit helps prevent bacteria and keeps your water pure. For a more thorough clean, gently scrub the inside with warm water and a soft brush every 3–4 days. Avoid using soap or harsh cleaners, since clay can absorb chemicals and affect water quality.” 

She continues, “Once a week, try a natural cleaning paste made from lemon juice and baking soda or coarse salt. These ingredients are gentle, effective, and safe for you and your matka. After cleaning, always let your matka dry in the sun for a few hours. Sunlight naturally disinfects and helps keep your pot fresh.”

How long can you safely store drinking water in an earthen pot?

According to Malhotra, timing matters when it comes to safety, especially during hot or humid weather. “As a dietician, I always remind people that water stored in an earthen pot should ideally be changed every 24 hours. Bacteria can grow quickly in warm climates, so it’s best to empty, rinse, and refill your matka daily. Ensure your matka is covered with a clean lid to remove dust and insects.” 

Quick tips for safe matka water storage: 

• Change water daily—especially in hot or humid weather 
• Rinse and refill your matka every time 
• Cover with a clean lid 
• Clean weekly with natural cleaners
