I have an extech pH meter that I would like to use to identify the spot prior to selecting a spotting solution. Should I identify the spot prior to cleaning or can I still get a proper reading after the initial cleaning?
Your normal cleaning routine will likely remove most spots without the need for any special treatment. Therefore you could spend a lot of time getting a pH reading on every spot prior to cleaning.
There are several ways that each help identify a spot / stain. pH is one of the ways. Using a pH meter on a particularly difficult to remove / identify stain can also be great marketing that sets your process and your business apart from others.
The presence of prespray or other cleaning agents will affect the pH. If you want to get a true pH reading after initial cleaning attempts, rinse out whatever else may be there beside the stain.
As much as you may think that a customer may appreciate a dog and pony show with lab coats, beekers, pH strips and pocket protectors and an explanation of their situation in Latin...
