Multipurpose Cleaners

Use these cleaners to remove dirt, grime, and stains from most surfaces.

Powder and gel cleaners are abrasive to scour surfaces such as porcelain and tile. Powder is more abrasive than gel and contains bleach to power out tough stains.

Cleaners in dissolvable packets are sized for dilution in 32-fl. oz. spray bottles. Their concentrated design means they take up less storage space than liquid concentrate cleaners, and they don’t require the use of gloves during mixing.

Parsley scented cleaners cut through scum and grease on granite, marble, and other high-shine surfaces without leaving streaks or residue.

Harsh cleaners are more acidic than other multipurpose cleaners. They are often used in lavatories to remove mineral deposits and soap scum.

Cleaners that meet Green Seal GS-37 are certified as environmentally safe for industrial use. USDA biobased cleaners are made from plant-based and pH-balanced ingredients. Cleaners that meet the EPA Safer Choice Standard are made of environmentally friendly ingredients. These cleaners also help you meet LEED Green Building standards.

Toilet Bowl and Urinal Cleaners

Dissolve mineral deposits and erase stains in toilets and urinals with these acid-based cleaners.

Cleaners with 9% hydrochloric acid are suitable for most cleaning jobs.

Cleaners with 10-30% hydrochloric acid remove even the toughest stains and mineral buildups. Note: Use on acid-resistant surfaces only.

Cleaners with 20% phosphoric acid handle a variety of cleaning jobs. You can use them where hydrochloric acid cannot be used.

Cleaners with 3-7% citric acid are good for light duty cleaning. They contain cedar oil to deodorize as they clean.
