removing scaling from air cooler

Aaj Kal bahut agrmi lag rahi hai aapko ? 

Cooler mein kaai kaise jam gai bhai

scaling and kai are different things, if its scaling use atomic washing machine cleaner powder with hot water and let it sit for 2 hrs

Toilet cleaner wala acid. ( HCL)

You haven't mentioned or posted a photo of what kind of cooler you got.

If its a regular cooler, scaling forms in the upper tray and the water tank at the bottom. These are plastic parts and can be disassembled easily. Just need to remove some screws. A cooler is a very basic appliance. Nothing complicated. Once you have dissembled and separated the water pump from the bottom tank, use bathroom acid or any toilet cleaner like harpic, to dissolve the scale. They will be gone in a minute and will be shining like new. Wash the plastic parts and reassemble.

Bhai.. kai ka pata nhi.. but scaling k lie kisi metal like rod, spoon, ka use kr skte ho.

Clean cooler once in season starting. Nothing special is required for that.

Cooler ki party Bhai?? Paytm krdo 4-500😺

22g cooler kabhi use nhi kara 20+ saal se, how can I help? Harpic try karlo. 😂

AC ke time mein ye gareeb cooler waale log kaha se aa gaye? 😜Vikas kaha hai? Joking though😛

Sprinkle bleaching power in cooler water tank leave it for a few hours or a day then use a hard brush to remove Kai. Don't use acid if the tank is of metal.

Plastic - harpic

Lohe ka - use diluted content of  acid bottle (tezab ki bottle usually u will find this on hardware stores )
