•What type of wheels to be cleaned, is one of the "determinates" for wheel-cleaner selection---homemade, or not.
•Just the other day there was a thread where an Ohio-based company's specifically formulated to be a non-acid wheel cleaner (that contained sodium hydroxide) was being used.
-One of the results of doing so, was that the end-user of this product received several painful chemical burns.
•Now even though they are not specifically formulated to do so...I will say that the same result can be obtained when using most NaOH-based drain cleaners, as homemade wheel-cleaners.
