Do you always have to wash clothes after wearing them just once?

There is reportedly a proper washing cycle for each type of clothing, so let's take a look at some useful laundry tips to keep in mind.

According to a laundry and cleaning cycle guide provided by the American Cleaning Institute (ACI), underwear, socks, and T-shirts are best washed after being worn once.

On the other hand, pajamas should be washed after wearing them 3 to 4 times, and jeans after about 3 times, though they should be washed immediately if they get dirty.

It is recommended to wash coats 1 to 2 times per season, and bed sheets at least once every two weeks.

However, you should not judge solely by the smell; it is best to check for stains, sweat, and how long the garment has been worn, and wash it as needed.
