Can I Leave Drano Max Gel Overnight?

Yes. In the case of a difficult clog, it is safe to let the Drano max gel sit overnight. Drano max gel clog remover is used on garbage disposals and other drains to remove any clogs. The gel takes about 15 to 60 minutes to unblock the pipes depending on the clog’s kind and size. 

In other cases, however, the gel can cause PVC pipes to break by loosening the glue that binds them. This is because of its corrosive nature. Generally, synthetic cleaners contain chemical components such as sodium hydroxide (NaOH) and sulphuric acid (H2SO4). These chemicals are corrosive therefore eat away both metallic and plastic pipes. Nonetheless, they work faster on clogs and are cheaper but cause problems. 

How Do Drano Works?

Drano max gel contains sodium hydroxide, sodium nitrate, aluminum, and sodium chloride. When the chemical cleaners come in contact with water, it generates heat. As a result, the heat melts or dissolves the clogs. Hot water rinses off the dissolved clogs, therefore, unblocking the drainage.

How To Use The Drano Max Gel

First, open the cap by pushing it down and turn it anticlockwise. In case of spillage, clean up immediately. Pour the gel over the drain slowly; for slower drains or difficult clogs, pour more. Then give it 15 minutes or 30 for tougher days. Finally, flush or rinse it with water. Repeat the above steps if it is not completely unclogged.
