Example Input: [header] How to remove paint from a car exterior [title] Park the car on top of a large tarp or drop cloth to contain the old paint. [step] The old paint should be disposed of instead of letting it contaminate the ground. If an open area is not available, park the car inside a garage, but open all of the garage's windows and doors for ventilation. <sep> (A) Cover objects inside the garage to protect them from the paint dust. [title] Use masking tape to cover the areas of the car that won't be sanded. (B) Alternatively, use a flashlight to check beneath the tarp. [title] Use an old baseball bat, crowbar, pry bar, or other large object to push the old paint off of the vehicle. (C) [title] Wipe the paint with a wet cloth, a roller wrap or an old towel to protect it from oil and water.

(D) If your garage is not well ventilated, a ventilation device will block your windows when the old paint has dried to a mud-like consistency. [title] Pour a small amount of vinegar into a small bucket.

Example Input: [header] How to lance and drain a blister [title] Assess the blister before choosing to drain it. [step] Not every blister needs to be lanced. In fact, some experts recommend that you should only drain blisters that are exceedingly painful, in weight-bearing or high-contact areas, or larger than 0.8 inches (2 centimeters) in diameter. <sep> (A) [substeps] If the blister is intact and manageable, try to keep it intact. Apply a piece of moleskin, adhesive felt, or tape. (B) In these instances, you need to check the blister to determine if it needs a leak-proof drain. [substeps] See the " how to drain a blister " section of this article for instructions. (C) [title] Make a decision whether or not to drain the blister. [step] If the blister is very painful, medical sterilization is an option. (D) [substeps] There is no one right way to do this, so you have to be sure that you have the right technique. It is not as easy to clean a blister as to rinse with water and applying a sterile dressing.
