These Smart Sponges are both hilarious to me… and actually a really good idea. How many times have you cleaned your toilet and then a few days later forgot which sponge you used? Well I have! Even though cleaning is my husband’s department… the odd time will arise where I’ll feel the need to clean what has become of the loo and will look for the sponge/cleaning articles under the sink. But how do I know which sponge is for the toilet and which for the sink? Quite frankly I don’t… and for 95% of you out there… you know you are just like me and guess! But hey, we don’t need to scare our guests away any longer… the smart sponge… our solution to the unknown!
