Tonyg 14 Report post Posted October 15, 2011 I have been given a couple hundred pounds of a d-Limonene based degreaserthat was sold to one of the dealerships for their garage. I have tried using on restaurant concrete but am unsure of the mix ratios and concentration. I typically use NaOH and hot water bhut thought I could use this to help with the surfactant, and maybe a little extra cleaning power. The 'orange' seemed to separate and float to the to and I didn't see any advantage and don't think the detergent by itself would be strong enough to downstream. I have contacted the manufacturer about some data sheets. Can NaOH and d-limonene be mixed? Share this post Link to post Share on other sites
