Review: WORKS -- all that matters - Zep is my 'go to' for a clogged toilet. Might not work on first try ... or second ... even third ... BUT it eventually works and isn't as 'messy' or gross as using a snake. ~half bottle, 12 hour wait, HOT water chaser for 15 minutes ... flush *use when the house has multiple toilets because the clogged toilet will be unavailable **IF you need immediate results, use a snake or call a plumber

## Questions & Answers

**Q: can you use this to clean the washing machine drain pipe?**
A: The Drain Care Buildup Remover help prevent clogs and remove years of buildup restoring the flow to slow running and partial clogged drains. For Drain Care® to work properly, you need to establish a partial flow so the enzymes can reach further down the pipes and start the cleaning process. 

To treat laundry lines: Pour 1 ounce of Drain Care into laundry line then flush with 16 ounces of warm water. Do not use for 6 hours. Repeat this process for 3 consecutive days. 

Use the Drain Care once a month in sinks, toilets, garbage disposal and grease traps to keep lines flowing freely.
