another experiment the test fabrics were immersed in the water solvent mixture as described in example 1 followed by agitation in a rotating cylinder for one minute in yet another experiment the test fabrics were immersed in the ultrasonic bath in the water solvent mixture as described in example 1 followed by agitation using ultrasound for one minute the reflectance results are given in the following table cleaning of mg35 cleaning of feox experiment delta r delta r water only ultrasound 10 7 19 9 solvent only ultrasound 1 1 0 5 water solvent agitation 7 8 16 2 in cylinder water solvent 20 22 9 ultrasound agitation the results demonstrate the synergistic action of the water solvent mixture and ultrasound the 75 25 mixture of water and hydrocarbon solvent df 2000 solvent from exxon was first subjected to one minute ultrasound agitation before adding the test fabrics in the next phase the test fabrics were added to the emulsion the fabrics with the emulsion were then agitated for one or 15 minutes in the cylinder a control experiment was done by agitating the test fabrics in the water solvent mixture in a rotating cylinder also for one or 15 minutes the reflectance results are given in the following table cleaning of mg 35 cleaning of mg.
