Question

I know there is a dilution ratio with chemicals when diluted with water, but recently my staff is putting less water in their mop buckets due to worry about spillage. . This concerns me due to not only the waste of chemicals but to the dilution not being effective. Are there procedures for properly wringing out a wet mop? Example: You should have enough water to rinse mop out before wringing out the mop. We typically use a 26-31 quart bucket.


Answer

You may have to provide a written procedure for your staff, since they obviously need to follow one that will avoid wasting time and chemical.
The first problem with only having a small amount of water in the mop bucket is accelerated saturation levels in the cleaning solution. Let me explain. If you have a 26 quart mop bucket and fill it half full, you would have 13 quarts of clean water. If the disinfectant mix ratio called for oz. per gal, you would add 1.625 oz. of disinfectant.
Now, at this dilution ratio, you should be able to mop a given amount of floor (usually 600-2,000 sq. ft. depending upon the soil load and type of soil being removed). If you add only 6 quarts of water to the bucket, the cleaning solution would reach a soil saturation level much faster and you will have to change the solution sooner.
Secondly, using less water sets you up for mopping with a dirty solution as well as a dirty mop. With only a slight amount of water, there will be insufficient rinsing action of the mop head. How often would you take a bath with only 1 inch of water in the tub?
If the workers are concerned about spillage, ask them to curtail filling above the halfway point. Always push by the mophandle with the mop in the bottom of the bucket, never in the press. Carry the setup over thresholds.
