How often should I wash my AC blanket or dohar in a Patna summer?

Twice through the season is the honest minimum. Wash it once when you first pull it out in March, and once around mid-season. If anyone in the house wakes up sneezing or stuffy only in the AC room, wash it more often than that.

Why does my clean-looking blanket smell sour when I take it out of the almirah?

That sour smell is bacteria feeding on old sweat. Even under the AC your body sweats all night, and the cotton blanket drinks it in and holds it for months. The almirah did not cause the smell, the unwashed sweat did.

Can I machine wash a cotton dohar at home?

Yes, a cotton dohar goes fine in the machine on a normal cycle, and warm water lifts the body oil better than cold. The hard part is drying it all the way through, folds included. If the inside stays damp it turns sour within a day, so give it full sun for hours and turn it once.

Could my blanket be behind the blocked nose I get in the AC room?

It often is. Dust mites need warmth, damp, and skin to feed on, and a summer blanket pressed against your face gives all three. If your nose blocks the moment you lie down and clears when you get up, look at the bedding before you blame the cold air.

What do I do if I have no way to dry a heavy blanket in the monsoon?

That is the main reason these blankets stay dirty, and it is a fair problem. A wet dohar needs a long stretch of hard sun that a Patna monsoon rarely gives. Hand the heavy things off to a pickup service that washes and dries them right through, so you get the clean blanket without a wet one hanging in a damp room for days.

The AC blanket you sweat under every night

It is 44 outside. You come home, shut the room, turn the AC to 24, and pull the thin blanket up to your chest. The dohar. Every house in Patna has one. Light cotton, folds down to nothing, comes out the moment the AC goes on.

You sleep under it every night from March to October.

Now tell me the last time you washed it.

You can't. Neither can I. Nobody washes the dohar.

Why it never gets a wash

The blanket feels clean. It is soft, it smells of the almirah, it never touched a plate of dal. So your head files it under things that stay clean by themselves. The bedsheet under you gets pulled off and washed. The blanket over you just gets folded and put back.

Then there is the size. A dohar does not fit in the bucket. Wet, it weighs like a sack. On the line it needs a full hard day of sun, and in a Patna monsoon you do not get one. So even when you think about washing it, the drying stops you. Back in the almirah it goes.

Months pass. It stays on the bed the whole summer.

What is actually in it

Here is the part people get wrong. The AC does not stop you sweating. Twenty-four degrees in a closed Patna room with the door shut is still warm against your skin, and your body pushes out sweat all night whether you feel it or not. The blanket sits right on you and takes it. Sweat, skin oil, the flakes of dead skin everyone sheds while sleeping. The cotton drinks it in and holds it.

That is one side. Now the top side.

The top side faces the AC. And the AC blows dust. The filter in most Patna homes gets cleaned once a year if that, so every night a fine grit of road dust and mould spores settles down onto the blanket. One side takes your sweat. The other takes the room's dirt. Neither ever gets rinsed out.

Pull the dohar out after a full summer and press it to your face. That faint sour smell, the one you tell yourself is just the almirah, is not the almirah. It is bacteria feeding on months of your own sweat.

The thing that keeps you up at night

Dust mites want three things. Warmth, damp air, and skin to eat. A Patna summer under the AC gives them all three. The blanket is the softest, warmest, most-fed surface in the room, and it is pressed against your nose for eight hours.

If you wake up in the AC room with a blocked nose, or you sneeze the moment you lie down and stop the moment you get up, do not blame the cold air. Look at the blanket. That reaction is your body arguing with what lives in the cloth.

Kids feel it first. The child who sleeps fine in the hall but wakes up sniffling in the AC room is telling you something about the bedding, not the temperature.

What to do about it

Wash it. Properly, and more than once a summer.

A cotton dohar can go in the machine on a normal cycle. Warm water lifts the oil better than cold. The real work is the drying. It has to dry all the way through, folds and all, or the damp that stays inside turns into that same sour smell within a day. Half-dry is worse than not washed. Open it right out in full sun, turn it once, and give it hours, not minutes.

Twice through the summer is the honest minimum. Once when you first pull it out in March, once mid-season. If someone in the house has a runny nose that only shows up in the AC room, make it more.

And clean the AC filter while you are at it. A blanket you just washed does not deserve a fresh coat of dust the first night back.

When you just can't dry it

This is where most people are stuck, and it is a fair place to be stuck. You know the blanket needs a wash. You have nowhere to dry a heavy dohar in July, no long stretch of sun, no line that holds the weight. So it stays dirty because the alternative is a wet blanket hanging in a damp room for three days, smelling worse than when you started.

That is the exact job to hand off. A dohar, a razai cover, the heavy things that will not dry on your line, come back to you washed right through and folded. You get the clean blanket without the two-day battle.

Go turn yours over right now and smell the side that faces you. Then decide whether it waits until March.
