    Question Bug that won't die

    I recently rescued three little phal's from a nasty awful nursery here in my area that had allowed several forms of bugs to infest the plants, they were also in bright sunlight and potted way wrong. So far I have managed to get a healthy color back into the little things, and most of the buggies are now gone. However, every morning i get up and there is a white powdery substance on the leaves again. I have soaped them, sprayed them with bug sprays, dunked them and re-soaped them and I still get up to powdery white stuff in the morning. Sigh...
    What kind of bug is this that I am missing???? And what on earth kills it?? Help...
    Here are pictures of them....

    that looks like spray residue to me.I have that same and nothing that I do will remove it,when its wet it can not be seen and you think that you have got rid of it.That is until the leaves dry

    My first guess would be mineral deposits. Doesn't look like any bug I know...

    Those are unfortunately stains from insecticide, hard water or concentrated fertilizer, and usually can't be removed. I have some on a few of my orchids too, but it doesn't seem to bother them at all. Just be happy to know that your new leaves won't have any burns!! :-)

    Looks like hard water to me too. What does everyone think about wiping them down with a solution of 1 qt of distilled H2O with a couple of drops of dish soap and a TBL of vinegar.

    You can also use Sunoil to get rid of the water mineral spots. When we sold commercially, it was very important to make sure the plants went out super shinny and clean. It is just normal, Connie. A good spray and wipe-down with some Sun Oil will make them look clean.

    Cheers,

    I use a wet cotton pad with a drop of lemon juice and the spots disappear magically, plus the leaves are shinier than ever. Don't leave those deposits for long or they start to burn the tips of the leaves.Try it.

    Thank You All so much....I will try the lemon juice...after inspection I would have to agree with the water spot thing. We have a system here where they re-use captured water and I'm guessing that would leave a water spot. I've really been on them every day looking for more bugs and haven't found any so far.
    Thanks Again

    I did look at them and the first thing I thought was vinegar (well I use it to get rid of scale in my kettle - so obviously that should be great for orchids right? ), but seriously so I imagine lemon juice would work really well. I shall have to look up BD's sunoil as I don't know that I have seen anything like that.

    Some of our garden centres do little packets of plant wipes which I think is quite funny. How many packets would I need to go through to keep my small collection bright and shiny?
