Ink
Did your pen explode on the carpet? You can get ink out of your carpet by using lemon juice and cream of tarter. Making this a paste and then letting it sit for about an hour on the stain; you can then begin the rinsing with cold water that will lift the stain out so you can blot it up.
Rust
Have you been moving things around in your home only to discover rust rings in your carpet from a piece of furniture? You can get rust rings out of your carpet by using a paste that you make from milk, lemon juice, cream of tarter and baking soda. Making a thick paste, rub this on the effected area and let it sit for about three minutes. Then you can rinse the carpet area with cold water and watch the rust wash away. Be sure to test this method for staining in a corner of carpet you never see in case it would bleed the colors in your carpet.
Grass stains
No matter where you live you might have a challenge known as a grass stain on your carpet. Most often you will get this type of stain right after the lawn has been mowed and then someone will wear his or her shoes into the house. So if you have a grass stain on your carpet use rubbing alcohol and warm water, pouring this solution on like you would a pre treat for a stain and then rubbing gently will pull out this stain. If you don’t have any rubbing alcohol in the house, you can use vinegar and cold water to pull out a grass stain by mixing ½ and ½ of each ingredient and then rubbing gently on the effected area.
Wax
To remove wax from carpeting you should first scrape away any excess. Then, using a warm iron and a clean cloth or even a paper bag simply place the iron on top of the cloth over the wax and as you iron the wax will adhere to the cloth instead of the carpet. Continue moving the cloth around as you pick up the wax so you are always using a clean section of cloth. If a little grease stain remains sprinkle on baking soda and let sit overnight before vacuuming which will remove the grease residue and deodorize at the same time!
Nail polish
Nail polish on carpets is a difficult situation to tackle, but with most cases you will find that straight vinegar (apple vinegar) will work the best on this nail paint while it is still wet.
White wine
White wine will leave a stain in your carpet. If you have discovered an area where a white wine or clear alcohol wine was spilled, you can use a cup of vinegar to four cups of water and pour over this area. Blot up and you will never know that wine had been there.
