# Is Affresh & Tide Washing Machine Cleaner Tablets Safe for Septic Tanks?

Affresh and Tide washing machine cleaning tablets use oxygen bleach (sodium percarbonate), sodium carbonate, and mild boric acid descalers to break down detergent residues, mildew, and limescale inside washing machines. When dissolved across a complete 15-to-20-gallon hot water cycle, the resulting chemical dilution is completely safe for septic bacteria.
