That sucks on your PJ. That advice wasn't from me. I have used the pre-moistened that I mentioned in previous post on my Samsung LCD and it worked great for me, but those do claim to be made for that task.
But, in general, I think you gave very, very good advice. Here's some more details:
1) Use the minimum necessary to get the job done. Good advice, min chems, pressure, wiping, etc. First, be sure you do no harm!
2) Good point to use only DI water! Tap water can / will leave residual ions, and it could be visible depending on the quality of your tap water. And if you use water, don't spray the electronics, like you said.
3) Yes, the best part about ivory is that it is a mild detergent and if I remember correctly perfume free too?
4) One place I disagree is on the dusting. The swiffer duster picks it up pretty well and removes it, not just spreading it around more. That being said, the no-rinse wash that you linked looks promising. I may grab some to try on your rec.
5) Those do look like very nice MF cloths, I may pick some up on your rec
Which brewing book are you reading. The classic rec is "The Complete Joy of Homebrewing"
The Complete Joy of Homebrewing Third Edition: Charles Papazian: 9780060531058: Amazon.com: Books
However, I have found one that is incredible. I have read maybe 10 books on homebrewing and this is by far the best that I have seen:
How to Brew
How to Brew - By John Palmer
How to Brew: Everything You Need To Know To Brew Beer Right The First Time: John J. Palmer: 9780937381885: Amazon.com: Books
I think this is a newer version than mine, as the cover is different. Anyway, after I read this one, I sold all my others except Joy. He is an engineer, and is passionate and thorough on the topic.
I am a chemist by profession and have been brewing beer for 10+ years. I used to brew every couple of weeks and have about 50 gallons on hand at all times. Now, I only brew a couple times a year. I mostly prefer the mini-mash method for the time savings. If you ever want to PM me on brews, I would offer any help that I could, but I'm not an expert in the all-grain arena, though I have done it a few times.
