You can not thoroughly remove the contaminants on the surface of a newly pressed Lp, an old shellac disc, a Diamond Disc, lacquer or acetate disc by running them under the tap even if the tap was RO-filtered or distilled water.
Unfortunately you can't thoroughly remove mold & mildew from any disc recording by simply playing it.
