No. This is a very harsh acid based product. If left on surfaces even when mixed in with standing water, an etching process will take place and permanently damage the finished surface of the fixture.
While the active ingredients are very similar, there are subtle differences that make them better suited for each applications.   For example:  Liquid Glug for the Kitchen uses a deodorizer designed to eliminate the smell of leftover food in the DWV system.
Spills/Leak Control: Spill area should be isolated to avoid possible exposure, and remove all ignition sources.  For small spills; neutralize with soda ash or lime, then absorb with sand, clay or diatomaceous earth.  Dike large spills; collect into an acid resistant container if possible otherwise cautiously dilute and neutralize with soda ash or lime, then collect or sweep neutralized material into an acid safe container for proper disposal.  Wash the area with large amount of water.
PT 4 or PT Bio1 are both designed for this application, but PT 4 is fast acting and PT Bio1 is better cleaning.
Glug is safe and easy to use for most common kitchen sink clogs.  If you think the clog is grease related, PT Bio1 may be your best option.
The most common Clog Buster failures occur because it was inserted into the drain pipe improperly. Clog Busters must be fully inserted into the drain pipe and not into an 90 degree elbow, or Tee fitting. These fittings allow for uneven expansion and eventual failure. 
This product is an herbicide and therefore must be registered with each state’s EPA.  Some states do not allow copper sulfate to be used as an herbicide.
PT Bio1 uses bacteria blends to completely digest and eliminate grease.  PT-4 uses solvents to liquefy it and move it out of the system.  PT-4 acts faster but does not completely digest the grease, it simply moves the grease out of the system.
Glug is composed of sodium hydroxide flake.  Many other similar products use sodium hydroxide prill (little beads).  The prill is denser and has less surface area.  Unlike the flake, it does not get caught in the clog as easily and therefore can pass through the clog without dissolving it.
Oatey believes that due to the dangerous nature of Clobber; it should only be used by professionals who know how to use, handle and store the product. Clobber should never be used by an individual that is not trained, and does not understand the dangers of sulfuric acid.
