Mildew growth on my sealer under sink

I have an under the counter sink. I have had mildew growing on the silicone sealer ever since the "professions" put it in. Can anyone tell me how to treat this w/out harming the silicone? I've tried just about everything, including bleach; which, my husband get furious w/me doing that because he said it will breakdown the silicone too fast. I personally think the installers used the wrong silicone; never had this problem before on anything. Thank you for your help....

I think you may be right. There are different silicones and acrylic caulks for any job. I have never had mildew grow on silicone for baths and kitchens. Usually on caulking which has the acrylic in it. you may want to have the caulk removed and go buy and put in the 100% silicone made for kitchen applications. Bleach usually kills everything and the mildew may be coming from under the sink and behind the silicone. Is it too late to call the professionals back in?

@C Renee Thank you for responding. I think replacing the silicone is going to be our only option :( I've done the bleach thing but & you can tell that it is inside the caulk. It is a very expensive counter & I waited too long to call the "outside" contractor back. When I contacted the company who we bought it from, said there ws nothing they could do. Sometimes you just have to learn in life... Again thank you Renee...

Renee is correct on this. The mildew if it is that will not or can not be removed once in the caulk itself. The lower quality silicons can stain easy causing them to appear that mildew is growing on it. IT needs to be cut off and away and then properly sealed using a high end sealant that has a anti-microbial added to it to prevent mold growth. Depending upon how long ago they did the sink I would insist that they come back and fix the issue. If they have used the proper materials. this would not even be an issue. As far as bleach. It will not harm the material you now have installed. Although all it will do is bleach the dark stain to a clear color. This makes you believe that the mold is gone, when in fact its simply bleached clear. Also even if the bleach did something to the caulk currently there, It would not matter because the proper fix is to remove it anyway and replace with a better quality material
