I can't say for sure whether that's just dirt, or something more insidious. I agree that combined with the odd patterns here, your interior paint problems worry me. If it's just dirt, I've tried pressure washing and I still find that the quickest and most thorough way to clean vinyl siding is with ordinary dish soap in warm water, and a scrub brush. To minimize the need for ladders, you can get scrub brushes that can be threaded onto extension poles, both at hardware stores. Telescoping extension poles meant for paint rollers fit these brushes. If necessary you can even lash a couple of poles together for a good long reach. Dampen the siding with a spray from the hose, scrub an area, rinse with hose, done. Don't go overboard with the hose pressure.

How to clean and remove spice stains from polymar white kitchen cabinets?

The fragility is not in the glass but in the lead came. windex will clean the glass and not harm it, but the ammonia in it may cause the caming to further deteriorate. They really need to be restored. Distilled water is not going to remove greasy grime. I would use a cotton ball and windex and be very careful to avoid the lead between the pieces of glass,

Hi Richard. For what it's worth, I looked at this bag, and I must say, I do like it myself. I could see myself purchasing it, going though the effort to clean it. Anyway, as for those stains. This one is complicated. For one, this bag appears to have a slight leather exterior, so it can't be soaked, or washed. And... I'm not sure that it would survive a dry-cleaning process either. Would I would attempt anyway is, taking a toothbrush, and full-strength rubbing alcohol and attempting to scrub the affected area in the interior of the bag, while keeping the exterior under a dry bath towel, to absorb any moisture and protect the leather. You could than attempt a very diluted dish soap soap solution, with some hydrogen peroxide on the stain, if the rubbing alcohol doesn't provide any relief. I'll say this though. It's my opinion unfortunately, that you will not be able to completely remove the stain, and you should only expect to be able to fade it, especially if this has been set in for a while. I hope this helps. :)
