How to Wash Flannel Sheets

Flannel sheets are a great alternative to turning the heating on at night. Thanks to the use of cotton, wool and synthetic fibres, they give the sheets a great feeling of softness and warmth which will turn them into your favourite winter sheets. However, they are winter sheets that require special care due to the mixture of fibres. If washed and dried properly, they will last longer and you will be able to enjoy them for many more years. OneHowTo will tell you how to wash flannel sheets so they won't go out of shape, lose their original quality or create lint.

Steps to follow:

1

Put your flannel sheets inside out in the washing machine to protect the fibres, and avoid lint appearing in the first few washes. Put your new sheets in on a low temperature wash at first, with a short programme which avoids using an intensive spin. For subsequent washes, the ideal temperature for washing flannel sheets is 60 degrees if the sheets are white, 40 degrees if they are coloured and 30 degrees if the fabric is very delicate. However, always use short programmes with a gentle spin cycle. Additionally, using a mild detergent specifically designed for delicate fabrics can further safeguard the integrity of the sheets, ensuring their softness is preserved.

If your flannel sheets are embroidered or frilly, you should take more care with how you wash them, as they could get damaged. You are best using a net. Place them inside this net before putting them in the washing machine. In this way, the embroidery won't spoil and will stay as new. For extra precaution, consider using a laundry bag, which offers even more protection against potential snags and tears during the wash cycle.

It is always recommended that you wash sheets separately in the washer without mixing them with other clothes so they have enough space to wash more easily and safely. In fact, given they require a special washing temperature and the use of detergents, it is not advisable to mix them given they are not washed in the same way as other clothing items. To enhance washing efficiency, ensure that the washer is not overloaded, allowing the sheets to move freely within the drum.

There may be traces of lint left inside the washing machine after washing your flannel sheets. If you're going to put another wash on, watch the clothes that you place inside so there is no lint remaining from the flannel sheets. It is best to rinse the machine before placing any other clothing inside. Consider running an empty rinse cycle with a bit of water and vinegar to thoroughly clean the drum and remove any lingering lint or detergent residue.

Don't use softener when you place your flannel sheets in on their own, as this product can cause balls of fibre, filling your sheets with lint and making them look older. Only use delicate fabric detergent. Moreover, to maintain the natural fluffiness of the sheets, consider adding a half-cup of baking soda to the wash cycle. This can help soften the sheets without the need for chemical fabric softeners.

5

When you take them out of the washing machine, as they haven't spin much, don't wring them out as you could make them go out of shape. You must hang them out straight away. If you place them in a dryer, do it on a low, almost cool, temperature. When taking them out, smooth out the creases with your hands and fold them up for storage. To further reduce wrinkles, consider laying the sheets flat on a large surface immediately after drying, and gently press out any remaining creases with your hands before folding.

6

One trick to make your flannel sheets last longer is to pour a cup of white vinegar into the washer and then insert the sheets. Vinegar sets the colour and prevents your sheets from fading after washing them. Instead of pouring vinegar directly into the washing machine, another option is to soak the sheets overnight in a little vinegar, and then wash them the next day with delicate fabric detergent. It should be noted that vinegar not only helps in maintaining the colour but also acts as a natural deodorizer, keeping your sheets fresh and clean smelling.
