Do I risk pissing him off and clean, or do I turn my back and shrug? [View all]

I'm visiting my Dad this weekend. He lives in N.Y. and I'm 8+ hours away in Virginia. I drove up to visit and as it was the last time I was here, his house is dirty and needs a good cleaning. It's not a situation where he is in danger, but it's dirty - scum on sinks, tub, dust on everything. The last time my sister-in-law visited and tried to clean, he was furious.

It could be that he doesn't see the dirt and dust that I can see, and more likely that he doesn't have the energy or desire to clean. My brother and I, along with our spouses, would happily pay for someone to come in and clean, but he won't allow it.

So, tomorrow, should I just hole myself up in the bathroom and clean it, and then just go from there?
