Is TFR also alkaline based then?
In the ph scale below 5 is acidic above 8 is alkaline
Neutral ph cleaner are in the range of 6-7 usually.
Ubic 2000 and most other cleaners are alkaline. After saying that some TRF's are caustic so are not ideal to go spraying on the likes of plastics or glass. Like most chems you should not allow them to dry on surfaces especially glass. Acid based cleaners will etch glass straight away as some have found out to their cost doing acid washes on buildings.
Safest type chems to use is Neutral ph cleaners.
