Remove carpet stains

You can lift out many stains from your carpet with vinegar:
Rub light carpet stains with a mixture of 2 tablespoons salt dissolved in 1/2 cup white vinegar. Let the solution dry, then vacuum.

For larger or darker stains, add 2 tablespoons borax to the mixture and use in the same way.

For tough, ground-in dirt and other stains, make a paste of 1 tablespoon vinegar with 1 tablespoon cornstarch, and rub it into the stain using a dry cloth. Let it set for two days, then vacuum.

To make spray-on spot and stain remover, fill a spray bottle with 5 parts water and 1 part vinegar. Fill a second spray bottle with 1 part nonsudsy ammonia and 5 parts water. Saturate a stain with the vinegar solution. Let it settle for a few minutes, then blot thoroughly with a clean, dry cloth. Then spray and blot using the ammonia solution. Repeat until the stain is gone.

Get out rug stains

Remove stubborn stains from rugs and carpets. Thoroughly dampen the area, then rub in some borax. Let the area dry, then vacuum or blot it with a solution of equal parts vinegar and soapy water and let dry. Repeat if necessary. Don't forget to first test the procedure on an inconspicuous corner of the rug or on a carpet scrap before applying it to the stain.
Give carpets a fresh scent

Then after you tried above tips Before vacuuming a room, sprinkle a little cornstarch on your carpeting. Wait about half an hour and then vacuum normally.

Deodorize rugs and carpets

How's this for a simple way to freshen up your carpets or rugs? Lightly sprinkle them with baking soda, let it settle in for 15 minutes or so, then vacuum up. Nothing to it!

Remove protein-based stains

Try a little tenderness to remove protein-based stains like milk, chocolate, and blood from clothes. For fresh wet stains, sprinkle on enough meat tenderizer to cover the area and let it sit for an hour. Then brush off the dried tenderizer and launder as usual. For stains that are already set, mix water and meat tenderizer to make a paste and rub it into the stain. Wait an hour before laundering as usual.

Good Luck !
