Potassium permanganate tablets, 10 tablets

Tablets: 0.2g/tablet
Dissolves to 6% in water. Use only the supernatant from saturated wool. Apply to stained areas (yellowing or mold) and leave on (use at room temperature, 25°C or below). Dissolving at higher temperatures can cause holes, but I like it for removing yellowing from wool knits at room temperature. Be careful in summer when room temperature is high. Always test in an inconspicuous area before use.
