But I still don't know if the "phosphorized" steel spot is to be rinsed with pure water afterwards! Any idea??? I heard that acid is still "eating" rust if not rinsed with water! But info or intox? All the best Bertie! …. see you in ….October???? In Ciney, if we are still alive! lol ! Thierry"

Hello Thierry

yes, I leave the rust remover on the helmet for about 30 minutes and rinse it off with water. If necessary I repeat the process again.
stay safe and we will meet in Ciney (I hope we see Walter also again)
