Deep Clean or Deep Wealth? The Vastu Rules of Pre-Diwali Sweeping, Mopping and the Broom

Why cleaning is part of the puja, not a chore before it

The belief behind Diwali cleaning is old and simple: Lakshmi enters a home that is clean, lit and peaceful, and her elder sister Alakshmi (also called Daridra, poverty and misfortune) lives where there is dirt, clutter and quarrelling. So the weeks before Diwali are spent throwing out what is broken, washing what is kept, whitewashing walls and fixing what leaks. In that sense the broom and the mop are the first puja samagri of Diwali. The rules that families follow about them every day become stricter in this season simply because the stakes feel higher.

The rules below are household and Vastu custom, followed widely but not uniformly. Where something is a strong, near-universal custom we say so; where it varies we say that too.

When not to sweep

Not after sunset

This is the most widely held rule. Evening is when Lakshmi is believed to visit, which is why the sandhya lamp is lit at that hour, and sweeping then is seen as sweeping her out with the dust. The practical root is just as clear: before electric light, sweeping in the dark meant sweeping away things you couldn't see, a dropped earring or a coin. If something must be cleaned after dark, wipe it with a cloth and keep the dirt inside a dustpan until morning instead of throwing it out of the door.

Not during the puja muhurat

Finish the cleaning before the puja, not around it. On Diwali, Sunday 8 November 2026, the Lakshmi Puja muhurat in Delhi is 5:54 to 7:50 pm, and Pradosh kaal begins at 5:31 pm. Aim to have the house swept, mopped and dry by mid-afternoon, so the floor is not wet when the rangoli and diyas go down.

Not on Diwali night after the puja

Many families do not sweep at all between the Lakshmi Puja and the next morning, even if diya oil drips or rangoli is smudged. The house is left as it is for Lakshmi. The first sweep is done at dawn the next day.

What about specific tithis?

You will see claims online that mopping on certain tithis at midday drives away prosperity. We have not found such a rule in a text we can point to, and we would rather not invent one. The time-based customs that are genuinely widespread are the ones above: no sweeping after sunset, not during the puja, and not on Diwali night.

The broom: where, how and which way

• Keep it out of sight. The broom is treated as a form of Lakshmi that removes daridrya, and a thing of Lakshmi is not left on display. Store it behind a door or in a cupboard, not in the drawing room where guests can see it.
• Lay it flat or hang it, head down. A broom standing upright on its bristles is widely considered inauspicious, and it also bends the bristles. Lying flat, or hung with the bristles pointing down, are both fine.
• Direction. Vastu guides usually place cleaning things in the south-west or west of the house and keep them away from the north-east, which is the corner of the mandir and of water. Never keep a broom in the kitchen near the stove or in the puja room.
• Never step over it or touch it with your foot. If you do by accident, many people touch it with their hand and then to their forehead, as they would a book.
• Don't sweep a guest out. Don't sweep just after a guest has left, or towards someone who is leaving on a journey.

The new broom of Dhanteras, and the old one

A new broom is one of the standard Dhanteras purchases, on Friday 6 November 2026. Families do it this way:

1. Buy the new broom on Dhanteras and keep it with the puja things. Some put a tilak of roli and tie a strand of white thread or kalava on it.
2. Don't use it on Dhanteras itself. Start using it from the next day, Chhoti Diwali.
3. Retire the old broom after the new one has come home, not before. Many families do this on Saturday 7 November, which suits the common belief that Saturday is a good day to remove an old broom. Avoid throwing it out on Dhanteras or Diwali, and avoid Thursday and Friday, which are linked with Guru and with Lakshmi.
4. Don't burn an old broom. Leave it at a place where waste is collected, or under a tree, out of the way where it won't be stepped on. If it is still usable for an outside area, many families move it to the courtyard or terrace instead of throwing it away.

The salt or alum mop

Adding salt (namak) to the mopping water is a common custom in the days before Diwali, and especially on Diwali morning and on Thursdays. Salt is believed to absorb negativity and stale energy; alum (phitkari) is used the same way and also cleans and deodorises.

How much

No text fixes a ratio. In practice, households use about one heaped tablespoon of coarse sea salt or crystal salt per bucket of 8 to 10 litres, or a small piece of alum about the size of a walnut, dissolved fully before mopping. More salt does not help and leaves a white film.

How

1. Sweep first, then mop. Mopping a dusty floor only spreads dirt.
2. Mop from the inside of the house towards the main door, and from the north-east corner outward, so that what is cleaned moves towards the exit.
3. Change the water when it gets dirty, and pour the used water into a drain outside, not into plants.
4. Don't mop on Diwali evening once the rangoli is down.

A caution for your floor

Salt water can dull marble, granite and polished stone over time and can damage wooden and laminate floors. On these, use a very light hand, or rinse with plain water afterward, or follow the custom only at the entrance and in the corners. Alum has the same issue on marble. Ceramic and vitrified tiles are fine.

A simple pre-Diwali cleaning order

1. From around 17 October: clear out broken things, old clothes, expired medicines and stopped clocks; repair taps that drip.
2. The week before: wash curtains and bedding, clean the kitchen and the storeroom, wipe fans and lights, whitewash or touch up walls.
3. Dhanteras (6 Nov): clean the mandir, wash the idols' clothes and the brass, and bring the new broom.
4. Chhoti Diwali (7 Nov): the bathroom, the main door and the threshold; retire the old broom. In many homes this is also the day of abhyang snan, the oil-and-ubtan bath.
5. Diwali (8 Nov): a last sweep and salt mop in the morning, then the rangoli and diyas; no sweeping after sunset.

In parts of Uttar Pradesh and Bihar, at dawn on the morning after Diwali, a woman of the house beats an old winnowing fan (soop) from room to room and out of the door, saying "Lakshmi in, Daridra out" (Ishar aave, daliddar jaave), and the fan is left outside. It is the same idea as the broom rules, made into a ritual.

Frequently asked questions

Is it really wrong to sweep after sunset?

It is one of the most widely followed household customs, linked with Lakshmi's arrival at dusk. If you must clean, wipe with a cloth and keep the dirt in a dustpan until morning rather than throwing it out of the door at night.

When should I throw away the old broom in 2026?

After the new one comes home on Dhanteras (6 November). Many families retire it on Saturday 7 November. Avoid doing it on Dhanteras, Diwali, Thursday or Friday, and don't burn it.

Can I use the new Dhanteras broom the same day?

The common custom is to keep it with the puja things that day and start using it from the next morning.

How much salt goes in the mopping water?

About one heaped tablespoon of coarse salt per 8 to 10 litre bucket, fully dissolved. No text prescribes an exact ratio, and more salt only leaves a film.

Will salt water damage my marble floor?

It can, over repeated use: it dulls polished stone and harms wood and laminate. On such floors use very little, rinse with plain water afterwards, or limit the salt mop to the entrance.

Where should the broom be kept according to Vastu?

Out of sight, lying flat or hung bristles-down, usually in the south-west or west of the house. Never in the north-east, the mandir or the kitchen near the stove.

Can I sweep on Diwali night after the puja?

Most families don't. They leave the house as it is for Lakshmi and sweep at dawn the next day.
