Do you know if OxyClean is as effective? I can find it for half the price of Oxy-Septic (per pound). Looking a the ingredients, Oxy-Septic contains sodium percarbonate and sodium carbonate. OxyClean contains those same two ingredients plus hydrogen peroxide. I don't know ratios of ingredients.
If I were to start with 30% hydrogen peroxide, do you know how much I would need for my pit? Thanks.
