Being new to 'soft washing ' I'm trying to figure out a formula for mixing 12% hypo. Is this accurate? Formula in 25 litre mixture.
12%. --- Hypo/litres ----Water/litres 5%. --- 7.5 ------- 17.5. 4%. ---- 6.25. ------- 18.75. 3%. ----- 5. ------- 20. 2%. ----- 4. ------- 21. 1%. ----- 2. ------- 23. For example. 4%= 3:1 ratio. Hypo= ( 25×1) / (3+1)= 6.25 litres. Water= (25×3) / (3+1)= 18.75 litres
