I did a demo for a local store on one of their pumps and the results are decent from what I feel. Any opinions or advice on how to get the stains to clear up a little more. I DS caustic (hot mix, 1gallon water, 5 cups of caustic), hot water, dwell time of about 10 min due to traffic at this store. I also went back over the area again with a wand in bad areas to brighten them up even more. Suggestions also the last pic is a different pump but just as dirty as the one before I cleaned it
