We are aiming to include water for sanitization of wet areas, such as kitchens, restaurants and toilets. Calculations/ assumptions:

- 01 bucket (15L) containing Water,

- 01 bucket (15L) containing Soap and Water, and

- 01 bucket (15L) containing Disinfectant Product and Water.

Thus, 45L of Water (03 buckets) as a set to sanitize 40 m2.
Do you agree with these numbers? Different perspectives are welcome.  
Thank you in advance.
