Rectorseal 45009 Acid-Away Its robust construction ensures consistentThe Rectorseal 45009 Acid Away is a professional grade compressor burnout acid neutralizer designed to address residual acid buildup in polyolester (POE) refrigeration oils. In the field, acid contamination is a primary cause of repeat compressor failure following a burnout. Unlike standard flushing agents, this chemical treatment chemically neutralizes acid molecules rather than just coagulating them, circulating through the AC and refrigeration
