iron and steel cleansing - Iron and Steel cleansing; iron and steel cleansing -
Take a spongy piece of fig-tree wood, and saturate it with a mixture of sweet-oil and finely powdered emery, and with this well rub all the rusty parts. This will not only clean the article, but will at the same time polish it, and so render the use of whiting unnecessary.
Bright iron or steel goods (as polished grates and fire-irons) may be preserved from rust in the following manner. Having first been thoroughly cleaned, they should be dusted over with powdered quicklime, and thus left until ready for use. Coils of piano-wire are covered in this manner, and will keep free from rust for many years.
Dissolve ½ oz. camphor in 1 lb. hog's lard, and take off the scum; then mix with the lard as much black-lead as will give the mixture an iron colour. Rub the articles all over with this mixture, and let them lie for 24 hours; then dry with a linen cloth, and they will keep clean for months.
Table knives which are not in constant use should be put in a case containing a depth of about 8 in. of quick lime. They are to be plunged into this to the top of the blades, but the lime must not touch the handles.
Steel bits that are tarnished, but not rusty, can be cleaned with rotten- stone, common hard soap, and a woollen cloth.
Brightening Iron Articles
When taken from the forge or rolls, the articles are placed in dilute sulphuric acid (1 to 20) for an hour; they are then washed clean in water, dried with sawdust, dipped for a second or so in nitrous acid, washed and dried as before, and finally rubbed clean.
