How to Get Dried Slime Out of Carpet
To get dried slime out of carpet, start by scraping and chipping away as much of the slime as possible with a butter knife or old credit card. Then, run a vacuum over the area to suck up some of the slime, and apply goo remover, WD-40, rubbing alcohol, or citrus solvent all over the area. Allow the cleaner to soak in for 10-15 minutes and then use a towel to wipe the slime and solvent away. After you wipe up the cleaner, blot the area with warm water to remove the cleaning solution. Be sure to let the area dry completely.
Scrape away the excess slime. If there's a giant blob of slime on your carpet, you should remove as much of it as possible. Scoop the excess away with a spoon or scrape it off with a knife, working from the outside to the center. Vacuum the area. Using your vacuum can help remove the slime so you can get to the stain. Vacuum the area in several directions to suck up as much of the dried slime as possible. You can use an upright vacuum or a handheld variety. Be sure the slime is dry before vacuuming so you don't clog up the vacuum. Choose your cleaning solution. Vinegar, rubbing alcohol, goo remover, citrus solvent, and WD-40 can all be used to remove slime and stains from carpet. Choose whatever you have on hand, or pick up the product of your choice from your local hardware store or superstore. Put on gloves and spot-test the cleaner. Wear gloves to protect your hands from the chemicals and the dye in the slime. Be sure to test the solution on an inconspicuous spot before treating the stain. Apply the cleaning solution to the carpet. Rubbing alcohol, distilled white vinegar, and WD-40 can be poured or sprayed directly on the carpet as they won't harm the carpet backing. Be sure to saturate the entire area. However, if you are using citrus solvent or goo remover, pour the product on a towel and press it into the carpet. Use just enough product to wet the slime and stain. This keeps the product from soaking through and dissolving the carpet backing. Let the solution soak for 10 to 15 minutes. It's important to allow the cleaning solution time to soften dried slime and penetrate the carpet fibers to remove the color. Wipe away the slime and stain with an old towel. After 10 to 15 minutes, use an old kitchen towel or a paper towel to wipe away the slime and the stain. You shouldn't even need to do much scrubbing! Toss the towel out when you're done. If stubborn spots remain, repeat the process. Rinse the area with hot water. Wet an old towel with hot water and wring out the excess. Blot the carpet with the towel to remove the cleaning solution and any remaining slime from the carpet. Remove excess liquid and allow the carpet to dry. Press a dry towel into the carpet to soak up as much liquid as you can. Then, allow the area to air dry completely.
