Rinse water reuse system and methods of use

A method for reusing water in a wash machine comprising:

• dispensing a cleaning composition into wash water of a wash tank;
• removing the wash water from a wash tank with a drain water transfer pump;
• moving the removed wash water to at least one reservoir tank in fluid communication with the wash tank with the drain water transfer pump;
• and
• transferring water from the at least one reservoir tank back to the wash tank with a reservoir tank water pump, wherein the at least one reservoir tank comprises an inner and outer chamber, the inner and outer chambers slope towards at least one reservoir tank water trap, and the at least one reservoir tank water trap moves water from the at least one reservoir tank to the drain or moves water from the at least one reservoir tank to the reservoir tank water transfer pump.

A method for reusing water in a wash machine comprising:

• preparing a chelating or sequestering agent and detersive ingredients in an aqueous pre-mix;
• mixing the aqueous pre-mix with water from a water supply during at least one wash cycle of the wash machine;
• removing ions from hard water that is a byproduct of the at least one wash cycle of the wash machine;
• binding metal ions in the hard water to prevent the metal ions from interfering with the action of the detersive ingredients other than the chelating or sequestering agent;
• removing wash water from a wash tank with a drain water transfer pump;
• transferring a recycled, about-0 grain water producing from using the water softening device and the chelating or sequestering agent from the reservoir tank into the wash tank using the reservoir tank water pump.
