I have gone through a lot of Sweets and it did an excellent job.
A few years ago I found Wipe-Out, all I can say is WOW
I don't know what Wipeout has in it but it smells awfully strong to me-much like ammonia. I have it but the liquid, not the foam.
XI. WIPE-OUT "PATCH-OUT" ™ contains NO ACID and NO AMMONIA.
