does anybody have a suggestion for this? What is it exactly, and how do I remove it? Here is a before and after picture from today. Here is what I tried: F9 Efflo at max recommended strength, NMD 80 at 4:1 as directed, and Aluminum Brightener as a last resort. As you can see, there is little difference. Does anybody have another suggestion. Thanks
If it isn’t efflorescence I’m assuming it would be calcite?
Send the pictures with what you have described here to customer support at Eacochem. They will usually have a response with an answer or more questions in short order.
Thanks, I just forwarded the information to them. I am thinking it must be calcite, which would require their presoak followed by nmd 80. I will let you know what they say.
Thank you
