Abstract
The present invention 10 discloses a cleaning device having a base portion 14 with a peel and stick adhesive 20 underside and a clear permeable topside 22 having a color reactive substance 24 contained therein wherein the base portion 14 further includes a malleable flap 12 disposed thereon. The present invention is to be placed in areas to be cleaned such as floors, walls, counters and the like for the purpose of monitoring the efficiency of the people that will be doing the cleaning. The peel and stick adhesive base 20 will maintain the cleaning detector 10 in place and the user will put the malleable flap 12 into a substantially perpendicular position relative to the base portion 14. The malleable flap 12 will be deformed away from the substantially perpendicular position if the area proximal to the present invention 10 has been properly swept, mopped, dusted, etc. Furthermore, the reactive material 24 beneath the permeable top sheet 22 will change color when a substantial amount of moisture has been introduced therein providing the user with useful information regarding areas to be wet mopped and/or wiped down with a liquid.
