Cold water with a little bit of dishwashing soap or hand soap is a handy and effective way of cleaning a spot. The exception here is silk as it tends to leave rings where areas are moistened. Most other fabrics can be beautifully spot cleaned. Watch That Heat Heat is one of the most destructive components in the cleaning process. The water, the dryer, the iron and its steam when too hot, all help shorten the life of a garment.
Fabrics are sensitive.
Too much heat at any stage can cause shrinking, yellowing, static, weakening, limpness and fading of colours. Washing Water at a low temperature is not as damaging to fabric as heat. Clean the spots off your garment first, then wash the overall garment in cold or tepid water. Drying I rarely put things in the dryer. If it is a fabric that needs to be fluffed up, I put it in for a few minutes.
