I’ve encountered this same situation in two of my clients houses, and I’ve got to find a way around it. Basically, a housekeeping client of mine will have a bathroom mirror with a row of lightbulbs directly above it. The mirror will invariably be covered in a ton of dust, just little white micro particles or hair, and I try to wipe it down with a rag and alcohol, (my typical method for glass that doesn’t involve wearing window cleaning BOAB on me when I clean their house) and that doesn’t work. As soon as any rag I have touches the glass, it just sucks up tons of little micoparticles from the rag, and the light shining down on it makes it extremely noticeable. So I end up going to the van and getting my window cleaning supplies, and I try it with a scrubber and squeegee. This gets about 60% of the particles, another 30% slide right under the squeegee, and another 10% just get dislodged into the air, and just magnetically attract themselves back onto the mirror. It drives me nuts. It’s impossible, by these means, to get a clean mirror, and because of the direct illumination of the dust and fibers, it looks horribly noticeable and I need to find a work-around, fast.
I’m not 100% on the science, but I"m guessing the mirror is negatively charged. Perhaps the answer may have something to do with using a balloon, perhaps using it to statically charge or discharge a rag or something? Or using a really high quality microfiber rag, fresh out of the package, before it’s had time to latch on, and subsequently shed, other fibers, (like they all seem to do in my experience)?
Has anybody else encountered this, or have any ideas?
