Chappy 138 Report post Posted May 9, 2007 This fence along with the rails and some benches was added to a deck I finished in Dec. Only needed cleaning so I used efc 38 and did not neutralize. Question is, How would you neutralize this fence as the spindles are copper? any acid will discolor them and may cause permanent damage? I did put a drop on one where it wouldnt be seen and got an instant color change. Share this post Link to post Share on other sites
0 bigchaz 157 Report post Posted May 9, 2007 With efc I thought you dont necessarily need to neutralize? Maybe you could just stain as is for this one Or maybe brushing acid on then rinsing? Share this post Link to post Share on other sites

0 Greg R 82 Report post Posted May 14, 2007 Try Citric Acid as opposed to Oxalic. Haven't done it but Citric is a much weaker and safer acid and it may not have the same effect oxalic does on the metals. Share this post Link to post Share on other sites
