How do you remove the default Bootstrap 3 carousel control background gradients?

Question

I'm pretty sure this is the code I need to modify, but for some reason I can't get the gradients to disappear in IE. I want them completely gone!

.carousel-control {
text-shadow: none;
opacity: 1;
filter: alpha(opacity=100)
}
.carousel-control.left {
background-image: -webkit-gradient(linear, 0 top, 100% top, from(rgba(0,0,0,0.5)), to(rgba(0,0,0,0.0001)));
background-image: -webkit-linear-gradient(left, color-stop(rgba(0,0,0,0.5) 0), color-stop(rgba(0,0,0,0.0001) 100%));
background-image: -moz-linear-gradient(left, rgba(0,0,0,0.5) 0, rgba(0,0,0,0.0001) 100%);
background-image: linear-gradient(to right, rgba(0,0,0,0.5) 0, rgba(0,0,0,0.0001) 100%);
background-repeat: repeat-x;
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#80000000', endColorstr='#00000000', GradientType=1)
}
.carousel-control.right {
background-image: -webkit-gradient(linear, 0 top, 100% top, from(rgba(0,0,0,0.0001)), to(rgba(0,0,0,0.5)));
background-image: -webkit-linear-gradient(left, color-stop(rgba(0,0,0,0.0001) 0), color-stop(rgba(0,0,0,0.5) 100%));
background-image: -moz-linear-gradient(left, rgba(0,0,0,0.0001) 0, rgba(0,0,0,0.5) 100%);
background-image: linear-gradient(to right, rgba(0,0,0,0.0001) 0, rgba(0,0,0,0.5) 100%);
background-repeat: repeat-x;
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#00000000', endColorstr='#80000000', GradientType=1)
}
.carousel-control:hover, .carousel-control:focus {
opacity: 1;
filter: alpha(opacity=100)
}
