A.) ___sq.ft.divided by 500=_____ gallons of daily
cleaner used per day. (One gallon should do 750 sq.ft. Using 1 gal per 500 500sq. Ft.
provides for a margin of safety).
B.) To determine which drum to use, start with a 15, 30 55 gal.
Drum. Mix 6 parts water and 1 part cleaner for unglazed tile and and mix 12 parts water
and 1 part cleaner for glazed tile. Use the formulas below to determine the time that a
15, 30, or 55gal. Drum will last.
i) Drum Size X Ratio
=
Drum Size Total
_________X_____= ________+________=______
1 55 gal drum at 6:1 yields 385 gal.
1 55-gal drum at 12:1 yields 715 gal.
1 30-gal drum at 6:1 yields 210 gal.
1 30-gal drum at 12:1 yields 390 gal.
ii) Gallons of cleaner available (i
