How to remove IE's Select Drop-down box arrow icon

Select {
   width:100%;
   height:34px;
   Border:solid 1px #0086EA;
   /* For the dropdown small arrows to leave a little position, to avoid being covered with text
   /padding-right:34px;
   padding-left:10px;
   /* Clear the Default Select selection box style
   /appearance:none;
   -moz-appearance:none;
   -webkit-appearance:none;
   Background:url ("/assets/img/caret.png") no-repeat scroll right center transparent;
}
/* Clear IE Default selection box style clear, Hidden Drop-down arrow
/select::-ms-expand {Display:none}

Suitable for use with projects, with pictures for select background. Clears the default style for individual browser select.

Currently applicable to Ie10 and above
