Just wanted to share with you a cleaning solution I've come up with. I'll probably make a How to/Informational youtube video in the near future, in case anyone is interested.
This is the most economical, effective, and safe method that I've found in my search for a cleaning solution. The following concentration will sanitize[SUP]1[/SUP]. Make sure that it says "Cleans and Disinfects", and that there is an EPA registration number on the label of the original bleach bottle.
Desired Final Concentration
Concentration = 0.02%This is the CFOC National Health and Safety Performance Standard used in child care centers for food-contact items (eg. dishes, utensils, etc).
Dilution equation
C[SUB]1[/SUB]V[SUB]1[/SUB] = C[SUB]2[/SUB]V[SUB]2[/SUB]
(Concentration of original bleach)(Volume needed of original bleach) = (Final Concentration)(Final Volume of Diluted Bleach Solution)
Example:
Original Bottle of Bleach
Concentration = 8.25%
*Note: I'm using a concentrated bottle of bleach. Check the concentration of your starting bleach (found on the back label), as regular bleach is usually 5-6%
Desired Final Volume
32 oz Converted to mL = 946.353 mL
*I chose this final volume since I have a spray bottle of that size
(0.0825)(X)=(0.0002)(946.353mL)
X = 2.3 mL of bleach
Add 2.3 mL of bleach to spray bottle. Fill with water up to 32 oz mark.
*Note that you are not adding 32 oz of water to 2.3 mL of bleach; you are adding enough water so that 32 oz is your final volume.
I used a spare syringe to measure the 2.3 mL.
NOTE:
You do have to make this solution daily, or as needed, for maximum effectiveness, as bleach will break down into salt and water[SUP]2[/SUP].
[HR][/HR][SUP]Footnotes:
1 [/SUP]Meaning, kill 99.9% of germs on a surface in a shorter period of time; whereas 'disinfect' means to kill all germs listed on the label in a longer period of time or with a stronger solution. Spray onto pre-cleaned surface, allow to sit for 2 minutes, then wipe off or air dry.
[SUP]2 [/SUP]There are different factors that affect the degradation of diluted bleach solutions, including temperature and light, which is why bleach is sold in opaque bottles. The pre-diluted solutions of bleach available on the market contain stabilizing agents. The one that I currently use (since I have a bottle left) is Clorox Anywhere Hard Surface, because it's safe to use on food-contact surfaces. Note that the bleach concentration is 0.0095%. It's also kind of expensive, since I use it liberally, which is why I started researching to make my own.
[HR][/HR]DO NOT MIX BLEACH WITH ANY OTHER CLEANING CHEMICALS.
Please, please follow safety protocols and instructions found on the manufacturer label.
