You may know some or even all of these, but these are some tips and tricks that I use and love.
1) If you don't have a cake tester and are out of toothpicks, you can use a raw spaghetti noodle to test your cake.
2) If you have dried food splatter in your microwave that feels like it has been plastered on, take a coffee mug and fill it 1/2 full of water, and put it in the microwave and "cook" at 30 second intervals until the mess just wipes right out.
3) If you have food "glued" on your child's high chair tray, take a dish cloth/towel and run it under hot tap water. Lay the cloth on your child's high chair tray (completely covering the dried food) for just a few minutes and wipe clean.
4) If you use the right kind of soap in the bathtub/shower, it will leave little or no soap scum which makes clean up easier (I found out Dove soap is great). *I do not get anything from Dove for making that statement, it is purely my observation.
