Ideal choice for monthly drain maintenance, to prevent odors, rust, and future clogs. Proudly made in the USA and lab tested for guaranteed drain opening performance. Starts working on contact to cut through blockages and clear slow flowing drains. Dissolves minor hair clogs and grease allowing drains to flow freely again. Cuts through standing water to reach clogs. Great for kitchen, bathroom, shower, and tub drains. “No-glug” bottle with specially designed handle virtually eliminates splashing and makes pouring easy. Phosphate free and is safe for garbage disposals, septic tanks, and all pipes…even plastic pipes! Usage directions: 1) Pour half of bottle slowly into drain. 2) Allow to work for 15-minutes (tough clogs allow 30-minutes). 3) Flush with hot water. Repeat 1, 2, 3 if clog persists. For garbage disposal drains follow the same directions. ***Do not run disposal if drain hasn't cleared, Mr. Plumber could splash up and out: consider contacting a plumber. Pour directly into drain to clear clogs with standing water. Mister Plumber is formulated for light clogs and monthly maintenance, for heavy clogs we recommend our gel drain opener.
