Insert 23-INCH flexible TOOL into drain opening as far as it will go. Never force tool into drain. (Some drain stoppers may need to be removed to accommodate tool.)
Move the tool up and down two inches to loosen clog.
Carefully remove tool from drain as clog material may be attached. Immediately dispose of tool before proceeding. Do NOT attempt to use tool after pouring Pro Concentrate Gel down drain, as product could splash up during tool use.
After discarding tool, slowly pour entire contents of Pro Concentrate Gel bottle down the drain.
Allow to work for 30 minutes.
Flush drain with hot water to clean away remaining clog material.
IMPORTANT: Open carefully. Do not squeeze bottle, avoid splashing, and clean spills at once. Never use a plunger during or after use of DRANO® PRO CONCENTRATE GEL because product may still be present if drain is not clear. Do not reuse empty container. Replace cap before discarding.
Do not mix DRANO® PRO CONCENTRATE GEL with other household cleaners as hazardous gases may be released. If gases are released, leave area immediately—ventilate if possible.
