Thanks Kurt!

Looks like the manufacturer is fine with any mild cleaner. We'll let the painter have the fun!

Cheers,
Louis

Latex paint can be removed with alcohol. Probably a rag damped with it would do the trick. It evaporates quickly. Still better check with manufacturer 1st.

    Thanks all! We're working on getting in touch with someone from
    the module manufacturer who can tell us something substantive
    before proceeding.

    paint is still curing and hardening.  Paint doesn't stick well
    to glass, so probably mild soap and water ( manufacturer
    approved) and a nylon scrubby pad will  cure the problem.

    I agree with Jason -- call the manufacturer. If the modules

    If I am the customer, that painter just bought himself a row
    of modules.

    As a practical matter, I bet there is little problem with
    careful use of some kind of solvent, but who knows what the
    long term effects would be, and I certainly wouldn't take on
    that liability. Warranty could be an issue, if not some risk
    immediate damage.

    Call the manufacturer. They would be the best reference in
    this case.

    Hi Wrenches,

    We have an existing customer who just had their house
    repainted, and the painter oversprayed significantly on a row
    of modules. I haven't run into this particular problem before,
    and am at a bit of a loss about what to recommend to our
    customer for cleaning up this mess.

    Anyone have recommendations of cleaning products or techniques
    to use that won't damage the AR coatings or anything else on
    the module, yet will remove paint? Or for that matter, what to
    avoid?

    Thanks,
