The next time you make salad dressing, you can whip up an eco-friendly cleaner for glass, too. Just mix one part water, one part white vinegar and squeeze in half a lemon. Pour the concoction into a spray bottle. Shake it up, spray it all over your glass and mirrored surfaces and wipe it off with a cotton rag or sheets of newspaper. Just keep in mind that since the mixture is perishable, you'll need to use it up within 24 hours. But its lemony fresh smell will make you want to clean, clean, clean until it's all gone!
