How exactly should I apply this 1% salicylic acid solution for spot treatment?

Apply the solution directly onto the specific rough patch, congested area, or blemish-prone zone you wish to address. Use a clean fingertip or a cotton swab to dab a very small amount – a thin layer is sufficient. The formula contains alcohol, which helps it dry quickly, so you will likely feel it dry down within a minute. Since it's a 1% concentration designed for milder, targeted use, it can be applied once daily, or every other day, depending on how your skin responds. Always avoid the delicate eye area, mucous membranes, and any broken or damaged skin. It's best applied to clean, dry skin. After it dries, you can follow with your regular moisturizer if desired, especially if you experience any dryness.
