I find many of the popular products are easier to use when they are transfered to smaller containers like the 4oz flip-top soft plastic travel-size containers sold at Wal-Mart in the cosmetics section. Easy to open & close with one hand and dispensing just the right amount of product on a foam pad or MF applicator is a snap.
Personally, I found AIO & SG to be the worst because both products are so thin. You have to squeeze the bottle a bit when you pick it up and, if the AIO or SG is new, you can count on sending a geyser of product onto your work bench. Transferring both products to smaller containers made them easier to handle & dispense the small amounts of product that is needed.
I've read somewhere that Poorboy recommended flushing the sprayers with water (cold or warm ... don't remember) after using them or they could clog. I get a cup of warm water, unscrew the sprayer, put the plastic pick-up tube in the water & pull the trigger 10 or 12 times. Never had a problem with S&W, S&G, or BNB. I suspect the wheel cleaner is pretty caustic (never used it) so that sprayer should be flushed each time.
