Hard water marks on phrag leaves

[SlipperFan]

This is all interesting. I use milk applied with cotton balls and have had good success. If the spots don't come off right away, don't rub. Just leave a little on for awhile and then wipe it off.

And the winner is... drum roll please...

WD40!

Citrus base cleaners work well on all orchids. I use the stuff to clean up my plants to display at local orchid shows. Mainly lemon juice but I have used grapefuit juice too. Suger base juices tend to allow sootie mold to grow on the leaves after putting them back into the greenhouse. I've had bad luck with milk, if you don't get all the milk off. It will spoil and smell bad on the plants. Whatever you use follow up with plenty of water.

Thank you SlipperKing. The milk didn't work for me and I haven't been to the store to pick up lemon juice yet but I will.
