Different Chemicals than both Wichinox and Ospho. Both of these use Phosphoric Acid which is a good rust remover but will not remove the "free iron". Ospho is used where I live to remove rust on Carbon Steel
(barges) before applying a coating such as paint
. Phosphoric Acid will not remove "free iron" also confirmed by ASTM A 970 and Ospho. Give them a call.. Great product for removing rust from Carbon Steel
. They have been around for a very long time. I have never used it on Stainless.. I have used Wichinox with good success. We were looking for an easier way and more protection this is why we began working with different chemistry. We are working with surface Chemists who have long experience with cleaning/extending the life of Stainless Steel in aerospace, food
processing and pharma. The standard for removing rouge (rust), "free iron" and enabling a protective layer over the Stainless is quite high in these industries. Especially in products (food/pharma) digested by humans.
Hmmm.. I thought the photos show the metal to be shiny.. Maybe I need to do more crusing or take a photography
Obviously we are not professional photographers.
The welds in the photo
are from the anchor
carrier of a boat in eastern NC. I don't think the carrier was polished stainless. The owner recently purchased the boat and told us the Stainless has not been cleaned in over 20 years. At one time there was wood and varnish
on carrier. Spotless Stainless will not remove varnish
. It has been over three months and the welds look the same as in the after photo
. I speak with the owner monthly. He is quite pleased and using Spotless Stainless on all his Stainless.
We have had good success with stainless after cleaning
and get months before we see rust spots re-appearing. The spotting gets less and less as we continue to bath our Stainless with Spotless Stainless. We are in salt water
Nick we love Sundeers! They are the most beautiful boats I have ever been around. At one time we were considering a Sundeer 56. We have a soft spot for Dashew's boats..
Thanks all for your comments and good luck..
