Apply ACHM04-HG to ACF

After about 30 minutes, scrape off with a plastic knife.

Then wipe clean with a paper towel. It was found that although the ACF had been removed, the SR had been injured.

in conclusion:

Although ACHM04-HG ACF removal gel can remove ACF, it can also damage SR.
Recommendations for improvement:

1. When using ACHM04-HG ACF Clear Gel to dispense, be careful not to touch SR. In this regard, because ACHM04-HG belongs to the gel dosage form, it is possible to control the exposure range of the drug. And when using a plastic spatula to scrape off the ACF, pay attention to the direction of the scraper and scrape the gel to the outside to avoid contact with the SR.
2. Look for other agents that can remove ACF but not harm SR.
