To measure amount of cleaner delivered per spray.
Six 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.
Table 1. Beaker & Cleaner Weights
|Cleaner Name||Initial Wt. (g)||Final Wt. (g)||Cleaner Wt. (g)||Average Cleaner Wt. (g)|
|Jenny Glass Cleaner||101.1578||102.0659||0.91||0.95|
|Rejoice Glass Cleaner||102.25||103.90||1.65||1.82|
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
Both systems did not deliver cleaner at similar rates. Jenny Glass Cleaner’s average cleaner weight delivered almost 1 gram less (0.95g) when sprayed for 2 seconds when compared to Rejoice Glass Cleaner’s average cleaner weight of 1.82g when sprayed for 2 seconds.
