Product overview
Zep Commercial Liquid Heat Drain Unblocker 1L Professional Strength for Grease Fat & Food Build-Up
Zep Commercial Liquid Heat Drain Unblocker is a professional-strength liquid drain cleaner formulated for stubborn blockages caused by grease, fat and food build-up. The heavy-duty formula reacts with water and the blockage to help break down and melt away accumulated organic residue, restoring flow through kitchen drains and pipes. Zep identifies the product as particularly suitable for kitchen drainage applications and states that it is safe for use in plastic pipes.
The 1-litre bottle is designed for practical household and professional use. For general applications, Zep's instructions recommend removing excess standing water where possible, pouring approximately half the bottle directly into the plughole, allowing the product to work for at least one hour—ideally overnight—and then flushing the drain with hot water. If the blockage remains, the treatment can be repeated.
