The only method of removing the fur from the inside of a kettle is to chip it out with a chisel or other sharp-ended tool. An efficient method of preventing the deposition of the fur has yet to be discovered. An old-fashioned remedy is to have a marble rolling about in the kettle; when this has increased in size by the deposit it maybe removed and the chalky matter chipped from it before replacing.

A simple plan for removing fur from a kettle is to boil some common whiting in the vessel (watch carefully, as it soon froths over) and wash out. If necessary, repeat the process and then scrape out the softened fur. This does not damage the vessel as chiselling is apt to do. A wire should be passed up and down the spout until clean.
