Surface Disinfection
In order to disinfect your working surfaces, you may use either chlorine solutions, or alcohol. I prefer not to use alcohol, due to the fumes, expense, and flammability. It is much easier to make a disinfection solution in the following manner using chlorine bleach.
Using a measuring cup, take 2 parts (by volume) of 5.25% sodium hypochlorite bleach. Add to this 24 parts of distilled water. Mix thoroughly. Add to this 2 parts of household vinegar (5% acetic acid). Do NOT add the vinegar until the bleach has been diluted by the addition of the water! This solution is then added to a spray bottle. The solution is applied liberally to all surfaces that require disinfection; use of hand towels (inexpensive white dish towels from a discount store are perfect) to mop up the excess and wipe down surfaces is recommended.
When finished with the solution, unscrew the spray head, and pump clean water through the sprayer. There is no reason to clean the reservoir; as long as the bottle is tightly sealed and refrigerated while not in use, the solution remains stable for at least two months. However, the solution will corrode the working parts of the sprayer if left inside the pump, so flush it by pumping plenty of water through it.
