Treat the ice cream stains immediately to get the best results and avoid it from setting in permanently. If it is a washable cloth, put it into cold water for 5-10 minutes. If the stain is dried, then let is remain soaked in the cold water for 15 to 20 minutes. Avoid hot water, as it will cause the protein stain set in.
If the stain still remains, sprinkle lemon juice on it. Make sure that you do it while the fabric remains wet. Lemon juice should be enough to cover the stain. Hang the cloth in the open air to allow the sun to dry it.
If you can still see any remains of the stain, use an enzyme detergent. Take 1 table spoon of the enzyme detergent in a bowl and add two cups of water to it. Mix until the detergent is diluted. Using this mixture, blot the stain with a washcloth. Do not rub the strain as it can cause the stain to set in.
Rinse the cloth under running water.
Now add stain remover gel or spray to the stained area, and leave it aside for 7 to 10 minutes.
Repeat these steps until no ice cream is left in the cloth.
