If you've returned to your car to discover it's been dented, try using this guide to remove car dents using common household items. If one of these approaches works, it could save you hundreds of dollars in repair costs.

Step 1 - Car Dent Size

For this guide, the differentiating factor will be the size and texture of the dent in question. If the dent is larger than three inches and does not have a crease running anywhere through its body—then canned air will be your best bet. For smaller dents that do not have creases, you can utilize a plunger or your own brute force carefully to remove the dent successfully. Dents with creases pose a bigger problem and are a lot harder to remove than clean indentations—however, dry ice's many uses manage to stretch this far.

Step 2 - Larger Dents

Now that you have measured and examined the dent in question, you must obtain the appropriate product. For those removing clean dents with a span larger than three inches, apply your hairdryer to the area for one minute. Don't heat the paint so much that it begins to melt.

Next, spray the entire canned air contents onto the affected area—leaving the solution to dry. The dent should then pop out itself due to the opposition of hot and cold. Try up to three times—if you're still unsuccessful, the dent may be too small or creased to invert.

Step 3 - Smaller Dents

Try using a plunger on the affected area for those dents less than three inches in size. Whilst this may seem rudimentary and even laughable, the extent of a plunger's efficiency when it comes to this task is endless. Apply suction around the area and plunge repeatedly.

If the plunger cannot secure a clean attachment around the whole dent—it may not be an option. If this is the case and you can easily access the inside of the car panel, try gently using a rubber mallet.

Step 4 - Persistent Creases

For smaller dents that may also be creased, there is a sure solution to impress anyone who has the faith to try it. Dry ice is dangerous to handle and should only be touched when wearing thick protective gloves. The burns it produces are excruciating and anything but conducive to a pleasant day. Place the block of dry ice over the affected area and allow it to sit for a few minutes.

Repeat this process every few minutes until the dent pops out. Even fairly serious creased dents will manage to work their way back to the correct contours if given enough time. Even though there will be dents that are inevitably too severe to be removed in such a simple fashion—you will be amazed by the practicality and results these methods produce.
