Freeze wedges or whole citrus fruit in a heavy plastic freezer bag. When you need to use one, remove it and put into the microwave for a minute or two and then let stand for about 10 minutes before using.
Start with fresh cold water. Use the correct of amount of coffee (usually 2 teaspoons per cup) and choose the proper grind for the method of brewing. Drink coffee when it's fresh (if it sits around too long, it doesn't taste good). Wash coffeepot as often as you can - don't let coffee oils build up.
To remove large amounts, first sprinkle cornstarch or talcum powder onto the stain and pat in. When grease is absorbed, brush off. Use a prewash spray to further treat any remaining stain and then wash in the hottest water okay for the fabric (check care label). Check the stained area before putting into the dryer to make sure stain is gone. If not, give it a second treatment.
You can remove it simply by pouring a bit of cheap hair shampoo on a sponge. Then rub the filmy area, let it sit for a while and rinse with clear water. Try to do this after each bath or shower you take, so there won't be a buildup.
If you discover that you can't get a candle out of a votive holder, put it into the freezer until it's cold. Then the candle should pop right out. If small candlesticks have wax left on them that you can't remove easily, put them into the freezer too. When the wax is solid, it can be flicked off.
