How long can I leave soap on plants?

Hi. I'm wondering how long I can leave soap on houseplants?

For instance, I recently sprayed a lemon tree that had some scale bugs on it with diluted simple green. I figured it would kill more of them if I left it on for a while.

Hi Laurie, I only use ivory on plants. I found this on the simple green site, says its safe. Heres what else it said.

Grass or Plants� Is Simple Green� safe for vegetation?
Diluted Simple Green will not harm grass or flowers, but it�s always a good idea to rinse foliage after it has had contact with Simple Green and to water-in Simple Green into the soil. The wetting agents in Simple Green will help retain moisture in soil.

I spray with soap-treatments after the sun has passed, and I rinse in the morning
before the sun hits the plants again.
