Allow etchant to remain in place for 15 seconds. Etching time should be monitored with a stopwatch. Begin timing at the end of application. Option: Place etchant on enamel first, then proceed to cover dentin, for a slightly longer enamel etching time. 3. Rinse thoroughly (at least 5 seconds) to completely remove all traces of etchant. 4.
