I thought it might be a good idea to gather our greatest handy little tips and share them all. I discovered a good way to give the outside a great clean this morning. I couldn't locate the windex and rather than search, I tried a lazy alternative that worked so well. I got a wet wad if paper kitchen towel and poured a small drop of dishwasher rinse aid onto it. Gave my small tanks a good rub down and then a buff with dry paper towl afterwards and they are SO clear! figures, in hindsight, given what it does for dishes, lol. Please share any you might have!
