To remove stains of vegetables or fruits of any kind from cloth or wood, the following method is very good: The stained piece is first moistened with water and then placed in a jar or pail that can be covered. A lump of sulphur is ignited and dropped into the jar. Place the sulphur on a fire shovel when lighting it to avoid burns. The burning sulphur should be placed in the receptacle on the side where the stain will be exposed to the fumes.
The sulphur burns slowly so that the articles will not be harmed.
After the sulphur has burned away, the jar should be kept closed for a few minutes and when the articles are removed, the stains will be gone. This is harmless to try, and the cloth will not be injured if it is in a dry condition. The articles should be washed and dried as soon as they are taken out of the jar.
