I think Weiman used to be the recommended cleaner -- we still have our can from 518! A little goes a LONG way with that stuff!!! Just the lightest of sprays. Using more will just mean a lot more paper towels and not any cleaner....the towel to quantity ratio was exponential.
Cary told us during his orientation for 518 that they had a rental unit -- they would send out sometimes. WHen they hired a new employee, it was their job to prepare it when it came back so it was ready for the next trip. Part of the initiation was to tell them to use more than they needed so it would take a tremendous amount of effort to clean up the cleaner.
Barkeepers friend is my personal favorite thought at least when things get ....bad.
Aluminum cleaners. I'm not sure there is consensus yet. But, and this is NOT blessed by the nest....my choice is Sprayway glass cleaner. Its a aerosol can foam cleaner available at walmart and just about everywhere else. I use a disposable microfiber towel (also from walmart -- think microfiber meets paper towel in teh auto detailing section) I have been using it for a full year now and have had good results. However, as with any cleaner -- caution is always advised and you are using it at your own risk
