184. To clean Ermine and Minivar.—Take a piece of soft flannel, dip it in common flour, and rub the fur with it, being careful to rub it against the grain. Shake it well and rub again with the flannel till all the flour is out of it.
185. To clean Swansdown.—White swansdown may be washed in soap and water; after washing, shake it out, and when the down is somewhat raised, shake it before a clear fire to dry.
186. To clean Leather Cases.—To clean hat cases, writing-desks, &c., dissolve in warm water a small quantity of oxalic acid, and wash the articles with a sponge wet in the solution. When dry they will look almost equal to new.
187. To take Stains out of Linen.—Stains caused by Acids can be removed by wetting the part, and laying on it some salt of wormwood; then rub it without diluting it with more water.
Or, let the cloth imbibe a little water without dipping, and hold the part over a lighted match, at a due distance. The spots will be removed by the sulphureous gas.
