Perhaps some of the bottles are for occasional use, rather than every day, but even for hard to remove rust or hard water I just found out about "Bar Keepers Friend" which is an all purpose cleanser/polish. It was recommended for stains on my pots/pans (which it worked wonders on) and the website says it works for "stainless steel, porcelain, ceramic tile, plastic, copper, china, fiberglass, imitation marble, tile, grout, chrome, and composition sinks." It's derived from rhubarb and biodegradable. Some people even use it in their laundry as bleach. Especially now, when people are looking for ways to trim their budgets, it makes so much more sense to buy one thing that can serve multiple purposes than finding a separate tool for each and every mutation of the same basic problem (in this case- something needs to be cleaned).
On another note- it's spring! Instead of grading and planning this afternoon, I plotted out my balcony garden. The biggest difficulty at this point is figuring out if I really have space to leave the hammock set up all the time. I drew it to nearly to scale, but I haven't measured the hammock, so I'm not sure if I'll have room to tend to everything with it up.

I have full sun all day since my apartment is South facing. I tried to grow all of these things last year to varying amounts of success, except the strawberries, which are new. A school fundraiser was selling hanging strawberry kits, so I decided to try them out. Last year that spot was used for swedish ivy (another decorative) which will survive just fine in its indoor location. Now I just have to retrieve the soil from school (we're running an experiment growing peas in various conditions) and start the seeds. Except the carrots. I realize now that repotting carrots is highly unintelligent, so they will wait, and hopefully will be much less twisted this year.
