How long are most people using the detox pads for?

Last year my parents got some (very expensive) detox pads through an MLM. They worked great but at $10 a pad I never considered them. They were told you should use them every night for a month (minimum) or until the pads were clean in the morning. Does anyone know how long other companies are recommending to use? Anyone on this forum that has been using them for awhile, how long is it/ has it been taking to see improvement in the color of the pads in the a.m. when you take them off?
