Zep ZUATB128 Toilet Bowl Cleaner, 1 gal, Liquid, Fresh Wintergreen, Mint, Blue (Pack of 4)

Acidic toilet bowl cleaner quickly removes rust, dissolves organic stains and eliminates hard water residue from toilets and urinals. Its powerful 10% acid gel formula enables the cleaner to tackle even the most stubborn of stains. The thick gel clings to vertical surfaces, while its squirt top makes for an easy under-the-rim application. The formula's fresh wintergreen scent eliminates the harsh odor associated with most cleansers.
