I've been using some simple CSS and it seems to remove them and work fine.
input[type=number]::-webkit-inner-spin-button, _x000D_
input[type=number]::-webkit-outer-spin-button { _x000D_
-webkit-appearance: none;_x000D_
-moz-appearance: none;_x000D_
appearance: none;_x000D_
margin: 0; _x000D_
}
_x000D_
<input type="number" step="0.01"/>
_x000D_
