How should runner guides be cleaned?

The appropriate method for cleaning runner guides involves using a cloth dampened in mineral spirits. This technique is effective because mineral spirits are a solvent that can dissolve oils, dirt, and other residues that might accumulate on the guides during use. The gentle action of wiping with a damp cloth helps avoid damage to the material while ensuring a thorough cleaning.

Using a stiff brush, as suggested in another option, could risk scratching or damaging the surface of the runner guides, particularly if they are made from sensitive or softer materials. Similarly, soaking them in water might lead to water damage or warping, depending on the materials used in the guides. Using chemical cleaners could potentially leave harmful residues or damage the guides, especially if they contain harsh ingredients not suitable for the materials of the runner guides. Therefore, the use of mineral spirits strikes a balance between effective cleaning and preservation of the runner guides' integrity.
