Abstract (en)
A composition and method for cleaning papermill wire and felt are disclosed which use surprisingly effective combinations of organic cleaning components, such as N-methyl-2-pyrrolidone and gamma -butyrolactone (and certain of their structurally related compounds) with an alkali, such as sodium metasilicate and sodium hydroxide (and other alkali metal hydroxides), in both water and an organic cosolvent such as isopropanol, acetone, and 2-butoxyethanol (and other glycol ethers).
