8 years, 1 month ago8 years, 1 month agoAhhh ,@jkallmeyer, @john-christian, I forgot to mention that it is not biodegradable and ecologically harmful in it’s original high concentration. But you can release it very low concentrated with water. Just make sure that you reach a similar concentration like with laundry detergent (like I said it’s the same just higher concentrated. One last…[Read more]

8 years, 1 month ago8 years, 1 month agoHey guys,@jkallmeyer, @john-christian,
you can use Rewoquat diluted with Isopropanol up to 20% but the results are way better with the full strength. Like I said it is just a very high concentrated detergent (tenside) similar to the one used for laundry but much higher concentrated. The more you dilute it the worst it works. A good thing is that…[Read more]

I re-read the paper you gave us but I interpret it differently. The authors say they used “Rewoquat, a 75% solution of ….” So I read that as the Rewoquat itself is a 75% solution of the active ingredient.

8 years, 2 months ago8 years, 2 months agoHey @john-christian, it also very important to let dry wet fossils and especially fossil containing sediment blocks before using hydrogen peroxide. That way the pore space is free of water and ready to soak the H2O2. Otherwise the pore space is kind of blocked and the H2O2 will not enter … . The drier the sediment block the better.
cheers

8 years, 2 months ago8 years, 2 months agoHi Case (@case-miller) and John (@john-christian):
I have started a new forum for this topic you two suggested. I had to manually copy-and-paste your posts into the new forum, so it looks a little funky but it still works! 🙂 Keep the ideas coming!
Cheers,

I like to soak my fossils in hydrogen peroxide (cheap at Walmart). After it has soaked awhile and the bubbles have helped to get rid of the clay and silt in the nooks and crannies, I brush the fossil with an old toothbrush.
