Good calls all the way around except for the tshirts. No matter how soft they have become it is the cotton fiber that over time can cause fine scratching.
I really like the lenspen. Once you get any junk off like dust or dirt off the lens the microfiber tips in theory have some sort of cleaning solution on them, but the microfiber alone works just great.
I have solutions from a bunch of companies and they are all good but I use them sparingly.
