Sunnats and aadaab of wudhu

Washing the limbs of wudu without wasting water

Q: When I make wudhu it takes too long at times as I feel I am not wetting or covering all parts of the limb I am washing. This is also causing the wastage of water. What can I do to ensure that I do not waste water and over wash? If I rub water over my arms or legs 3 times (and try to cover all areas of the arm or leg) but not every single hair gets wet will this count as still being wet and my wudhu accepted? I would say my arms and legs take the longest.
