In the name of Allah, the most Beneficent, the most Merciful.
An object rendered impure by a solid impurity shall be washed until the body of the solid impurity has been removed. If after thorough ordinary washing (i.e. without soap, liquid etc) some impression like the colour or odour of the impurity still remains, then too the object will be regarded as purified.
An object rendered impure by an impure liquid, shall be washed and squeezed until one feels satisfied that the impurity has been eliminated. (Maraqi Falah p.64)
