Diluted Simple Green will not harm grass or flowers, but it's always a good idea not to saturate foliage. The wetting agents in Simple Green will help retain moisture in soil.
Simple Green should be diluted 150 parts water to 1 part Simple Green before use on any glass, mirrored or reflective surface. If used too strong, it will leave filmy, streaky, hazy marks. First attempt to remove this by wiping the surface down with a clean cloth and hot water. If the problem persists, Bon Ami, a common non-abrasive cleansing powder, will remove any stubborn residue, haze or streaks that may be left if Simple Green was inadvertently applied too strong.
Regular Simple Green contains synthetic sassafras (which is also found in root beer). Other Simple Green products (Multi-Surface Antibacterial, Lime Scale Remover, Pro Series Automotive, etc.) contain "masks", which are not as strong as fragrances, in floral, herbal or woody scents. Industrial Crystal Simple Green contains no added fragrance.
If you are experiencing foul odors from your dip tank/parts washer, you may have a bacterial contamination. We recommend adding an antibacterial agent in order to prevent bacterial growth and foul odors in dip tanks.
A word of caution: when adding foreign material into Simple Green, be aware that biodegradability, toxicity and sewerability issues need to be addressed by the additive manufacturer. Another option is to switch to Simple Green d, which contains a quaternary-ammonium disinfectant and takes much, much longer to become fouled by bacteria.
Simple Green evaporates at the same rate as water.
An aqueous additive used to keep soils dispersed throughout the cleaning fluid. Simple Green is an effective emulsifier.
Electrolysis - as it relates to use of Simple Green or other water-based cleaners
Electrolysis is the transfer of metal ions from one type of metal to another. Electrolysis needs a medium through which these ions can travel, and water is a good medium for this. Therefore, when cleaning metal parts or equipment, particularly in parts washing scenarios, it is best not to allow multiple metals to soak in the solution for any extended period of time. Evidence of electrolysis can be black or dull streaking on metal parts/equipment after prolonged soaking with other kinds of metals.

Disposal - Public Owned Treatment Works (POTW)
Simple Green is sewer disposable, however, the contaminant emulsified in the Simple Green/water solution may not be. Check with your local POTW before disposing effluent into drains.
Disposal - Storm drains
Clean Water Act of 1995 protects surface water and groundwater quality by forbidding putting any foreign material down storm drains. Do not dispose of degreasing rinseates into or near storm drains.
(Here's a tip: For home vehicle washing or exterior home cleaning, allow the used Simple Green/water mixture to fall onto the ground or grass. The non-toxic formula won't harm grass, plants, shrubs or trees, and the indigenous bacteria in the soil will consume the hydrocarbons [greases & oils] that come off in the rinse.)
