Can I pour drano down my washing machine drain?

No, you should never pour chemical drain cleaners like Drano down a washing machine drain pipe. Commercial chemical drain openers rely on harsh caustic soda or sulfuric acid designed to dissolve hair and grease in bathroom sinks, but they do not solve the root mechanical clogs common in laundry standpipes, such as lint compaction or long textile fibers. Furthermore, if the chemical fails to clear the clog and you have to disconnect the plumbing pipe manually, standing caustic chemicals can splash onto your skin and cause severe chemical burns or ruin appliance hoses. You can troubleshoot clogs safely using a mechanical plumber's snake auger. You can verify that your clearing method is successful when mechanical snaking breaks up lint blockages and allows water to flow down the standpipe without backing up.
