Question:

how do i keep soap build up out of the pressure sensing tubes?

I have speed queen commercial washers and the pressure sensing system becomes compromised by soap build up in the tubes that lead to the pressure switches. I have removed and manually cleaned each tube. Does anyone have experience with a chemical I can run through a wash that will disolve the continual build up and that chemical will not do damage to the rubber/plastic tubing?

Answer:

Soaps are soluble in mildy basic solutions, like ammonia. You might try that. Of course, if you're getting a build-up, it may mean your water is running high on calcium magnesium ions (i.e., it's 'hard'). In that case, water softeners may be your best best.
