Machine wash in warm (not hot) water on gentle cycle. You may use any mild detergent or soap. Use enzyme reactive stain removers only. Do not use chlorine, bleach, stain removers or detergents with lighteners. Never pour detergent or soap directly on your textiles. Either pour it in when the tub is full or dilute it. Do not use fabric softeners. These only coat the fibers and make them "appear" to be soft. Use one cup of white vinegar in the rinse water to remove any traces of soap and leave fabrics smelling fresh.
The ideal way to dry textiles is air only. A line or rod is perfect, but you can use a railing or shower rod as well. If you must use a dryer, use the lowest setting and never, never dry completely. During the last few minutes of a dryer cycle the fabric overheats and dries out, making it brittle and lifeless over time. Always remove them from the dryer while still damp.
We all take a towel for granted. Right? A towel is a tool. One of the first textile tools invented. It is almost certain that the original towel was hand loomed from linen.
The towel was used for drying after bathing long before soap was invented. Then approximately 600 years ago, the Turks began to weave the first towel that is still recognizable today, the pestamel. There are still some small factories hand weaving these flat woven cotton towels, used primarily in the Hammans. These pestamels have become popular recently outside Turkey.
As the Ottoman Empire grew, so did the use of the towel. Weavers were asked to embroider more elaborate designs, aided by their knowledge of carpet-weaving. By the 18th century, towels began to feature loops sticking up from the pile of the material.
So the looped cotton Terry towel that we know today was original invented as a decoration. Having said that, it was invented in Turkey and Turkey still makes the best looped terry available.
