What Customers Are Saying
Customers are divided on this drain cleaner's effectiveness. Many praise its success with light to moderate clogs, noting immediate or overnight results and ease of use without harsh chemicals. However, a substantial group reports complete failure on severe, grease-heavy, or deep blockages, often requiring professional plumbing services. Several users describe it as a waste of money when facing serious clogs. While some appreciate its simplicity and safety for garbage disposals, others note the cap is difficult to open. Overall, reviewers recommend it only for minor drainage issues, not persistent or severe obstructions.

Did not cut through grease
This product was our final attempt to clear our kitchen sink drain with chemicals. It did not work. We ended up physically routing out the drain which appeared to have a grease clog.
