I think if the counter top is oily then we need to use a hot water with bleach to dissolve it properly. If we use a cold water then the oily part will not clean.<a href="http://www.thertastore.com/Kitchen_Cabinets_s/857.htm" rel="nofollow">Laundry Room Cabinets</a> Fri, 24 May 2013 15:57:44 -0700 Larry Lopez http://www.europeanopticalsociety.org/dr-laundry/bleach-granite-countertops/#comment-841 http://www.europeanopticalsociety.org/dr-laundry/bleach-granite-countertops/#comment-842 This is a great question that is really two questions in one: how to solubilize oily residue on counters for easy removal, and is hot water suitable for a disinfecting bleach solution. It’s important to note that when using Clorox Regular-Bleach to disinfect counters, they should be cleaned first before applying the bleach solution (which by the way is ¾ cup Clorox Regular-Bleach per gallon of water). Water from the “cold” line should be used to mix bleach solutions. Since water doesn’t solubilize oil but heat does help with this, using hot water to provide the heat to break up the oil is one approach, and you could do this prior to bleaching the counters. However, if you want a one-step cleaning product for your kitchen counters, I recommend Clorox Clean-Up, a sodium hypochlorite based spray cleaner that in addition to bleach also has a surfactant to break up oily stains. It comes in a spray bottle, is super convenient to use, and is very effective. Hopefully this helps!
