It seems that my trees love the water here in Southern New Jersey, and the taste is terrific, but the water leaves a nice coating on the pots.
I know that if you wipe baby oil or Mineral oil on the pots, it does seem to slow down the process of the accumulation of the "white stuff", which I think is Calcium carbonate.
However, sometime one forgets to do the oiling, and the results is never noticed until a tree has been potted.
My question to all of you out there in Bonsai Land, has anyone ever found a commercial product that works? I have tried "Lime away", CLR, vinegar and elbow grease and a few others, but the results are lousy!
My solution is to mount a drill in a vise with a steel brush and slowly grind away the deposits. It does take time, but does not seem to hurt the glaze on the pots. I have used this method on unglazed pots and it makes them look like I had just oiled them.
Any other suggestions for the future
? I, and I think a few others would be most appreciative.
Here is one of my Shohin pots, which I wanted to show the before and after results.
