What Customers Are Saying

Customers overwhelmingly praise the product for quickly clearing grease and hair clogs in sinks, bathtubs, and drains, often on the first try within minutes. Many describe it as highly effective for stubborn blockages that other products failed to resolve. However, a notable group report complete failure despite following instructions, particularly with deep clogs or older plumbing, forcing them to use alternative solutions. Reviewers consistently warn of its caustic nature and emphasize the need for ventilation and caution. Overall, most customers find it effective, though results vary significantly by clog type.
