Every situation can be slightly different, from elevation to how dirty your HXStomp was before putting a switch on it. We've abused our personal HXStomp with about every cleaner under our sink and the finish is still flawless. That said, we cannot guarentee or warranty your personal device since we're not the ones working on it.
How we personally use this cleanup kit: Angle your HXStomp like it's on a pedal stand. Get some paper towels, and protect any encoder knob/switches to make sure any rogue cleaner gets absorbed.
The GooGone is in a dropper bottle. Squeeze the top, fill the dropper, and put just a few small drops on any left over adhesive. Let it sit for a few minutes, use the scraper, and gently clean/remove any soft adhesive. Repeat until it's nice and clean.
