Use dry shampoo and waterless cleansing towelettes or no-rinse liquid cleanser (sometimes called waterless bath) that you don’t need to rinse off, to feel clean. They’ll usually have those in personal hygiene sections of major pharmacies or in some larger groceries. We used those for my bedridden, blind grandmother for awhile before she agreed to get in-home care, then go to the nursing home.

In the meantime, does the townhome community have a gym/rec area that has a shower you can use? What about a nearby JCC, township rec ctr, or indoor pool that serves a community nearby? Sometimes you can pay a visitor/guest fee to use those. And if there are showers at work or your nearby church-run community center, use those.

If what is cluttering up your home is mostly garbage, maybe start there. Save the stuff you know you need to keep or use later, to sort later. It’s too much to deal with all at once. So don’t.

Even if you can’t make it spotless, make it useable and safe. Keep walkways and stairs open. Bag things. Box them. Open windows to get fresh air in to make it smell better. Throw out any garbage in the bin. Wash dirty dishes, pitch pizza boxes, take out containers, plastic wrappers. Wipe or dust things off. One thing at a time and first things first. Pick one thing per hour. Two things in the morning, two things in the afternoon. Whatever you can do.

And good luck.
