زجاجة مطوّر/مزيل برو-إيتش من مايكرو-مارك®، 16 أونصة

This sodium hydroxide solution cuts through my etched resist in under five minutes, and the 16 oz bottle has lasted through several boards without losing strength. It’s straightforward chemistry that just works—no fussing with ratios or heating.

The 16 oz bottle was enough to strip the resist off three of my circuit boards without any issues. I just let them soak for about 10 minutes and they came out clean.

Got my etch boards cleaned in one soak with the sodium hydroxide mix, no scrubbing needed. The 16 oz bottle lasted through a full batch of resists and the solution worked fast even at room temp.
