There have been several posters over the years who have expressed and interest in trying this and I have never seen one follow up with a message that they were successful. Theoretically, you could take the sds sheet of any chemical you like and emulate it, but chemical manufacturers are very careful not to post exact percentages and often list some things as “ trade secret”, so you never would able to copy something - and rightfully so.
This is something I would leave to the professional chemical companies. Save money by doing your own repairs, plumbing, electrical, do your own clean up, pits, etc. Don’t try to save money is a specialty area like this. It will end up costing you money and business because you will not be able to compete with CSI,
JBS, Simoniz, Quest, Chemquest etc. it’s not even worth trying.
