Have a natural pond in my backyard and am wondering what's the best/safest/most effective way to make sure it doesn't become a mosquito haven. With all the health risks from those bugs lately, I don't want to risk that.
Got some seriously dirty grout in the bathroom. What is the easiest way to clean it without spending hours scrubbing? I hate to use nasty chemicals but I think I'd rather do that than spend days scrubbing the stuff.
