Electronic cleaners safe for use inside iPhone

I just repaired a broken screen & bad battery on my iphone6 & while I was in there used CRC Contact Cleaner 2000 to clean a prior liquid incident that didn't kill the phone. The contact cleaner flushed a lot of contaminants out, but damaged the speaker housing. The phone works fine but the speaker sounds horrible. Clearly this was too agressive a cleaner, thought

Anyhow, are there any aerosol cleaners that are safe for the plastics used in the iphone6?
