New Washing Machine
If you are getting a new machine and want to start out under control follow these steps:
Note: These instructions essentially kick start the control process.
Use TechnoFresh® in the first three loads at 3 capfuls per load.
Then use normally as needed.
Since you are going to get detergent film on the plumbing as soon as you use the machine, you should put down a coating that has a high concentration of TechnoFresh® in it.
That would be the most effective way of starting out using the machine.
Even if the machine had been used already, a couple of TechnoFresh® shock treatment flushes, should get you back to a clean enough surface for this to also work.
It seems the contamination level is affected more by idle time rather than loads run.
So try to do this treatment within 2-3 weeks of starting to use the machine.
