The Kitchen!
I think this is the room you do the majority of the cleaning in just because it is used so much. I have a few tips to help get it clean without you doing the work.
1. To clean your microwave place lemon juice (if you have fresh lemon's use the juice of 1 and put the rest of the lemon in as well after it is squeezed. If you have bottled lemon juice use about 3 Tbs. ) in a microwave safe bowl and add 3/4 Cup water. Microwave for a good 3 or 4 Min's. Take the bowl out - be careful it will be hot!! Wipe with a cloth to remove all the gunk. Because of the steam it should wipe off with no problem. Plus you aren't using chemicals where you cook food so it is way better for you! You can also use vinegar but the lemon's make it smell so good!
3. Stainless Steel - There is no way around this one. If you truly want a streak free and shiny stainless steel you MUST buy a specific for stainless steel cleaning product. I have tried everything else and nothing works quite like the one's made for it. I like the Weiman Stainless steel wipes.
4. Sink - It seems like every kitchen sink could always use a good scrub. Whether you have stainless or porcelain I recommend Bar Keepers Friend. It is pretty inexpensive and it does all the work for you. You just wet the sink, put the powder on, rub it in and let it sit. I just spray it down with my spray nozzle and give it a quick scrub with my dish brush and it is done it a matter of a minute of work. I also always like to put some lemon's down the garbage disposal so it smells nice.
5. Dishwasher - Yep it needs to be cleaned too! Once a month I run mine on empty until the bottom is filled with water then open it. Add 2 cups vinegar and finish the cycle. It does all the cleaning for you, and I promise it will keep your dishes looking better than ever!
Happy Cleaning!
