Polishing up the pipes

[j3gq_imp]

I am not a chemist, so take my words with a grain of salt. But that much should be clear to all “pipe cleaners”. The better, more effortless a product does the job, the more aggressive it has to be. Whether it’s achieved with abrasive particles, or acid or a “special” formula. Short term speed may come at a price. Just my 2 bits.
(PS: my really stained pipes + my wide’s household wipe, ... it took me 2min per header, not exactly excessive).
