Hello again...

It's been a while since I posted here. I have 2 lemon trees (one I started from seed, and a 2nd tree grown from a cutting off the first tree). Since I had them in my kitchen during the winter, the leaves have developed a layer of grease and dust. What's a suitable way to clean the leaves? Is there something I can spray on them? I gently sprayed them with plain water, and although the dust came off, the leave remain greasy.

Thanks for the help!

Spray the tree with a Horticultural Oil, (UltraFine or Volk Oil), then after several hours flush the tree with the hose. The oil will soften the grease, and the hose spray will clean them. Apply the oil either early in the morning or just before dark, or on a cloudy day. never apply oil during the heat of the day. - Millet (1,333-)

Thanks, Millet! I will try it!
