Trial #4
To measure amount of cleaner delivered per spray.
Three clean beakers were pre-weighed. The selected cleaner was then held directly above the opening of the beaker and sprayed into each beaker for 2 seconds. The beakers were then reweighed and delivery amounts were calculated. A second test was conducted while holding the aerosol can upright and tipping the beaker to collect the cleaning product
