so I have found P21-S Wheel Cleaner Power Gel - Dr. O.K. Wack Chemie GmbH Online Shop and in north america we have the p21s wheel cleaning gel. are they the same brand at all? or the same product at all? they ship liters internationally thus eventually I may try this.
it is the same brand. the red gel is stronger than the green one NA gets i believe, but its just as safe apparently.
The red power gel is stronger than the standard gel. It seems to have iron dissolving properties . Tried power gel after using standard gel for years and it's so good I bought a 5ltr size.
P21S Wheel Cleaner (422) Red Gel Formula (pH 9.5) was a precusor to products like IronX and Wolf Chemicals Brake Duster. Originally there were some problems with international shipment
i went to checkout with a 5L container of powergel and a small note at the bottom says they cannot ship it to the US
OK. Now I understand why some of the S2000 wash & wax wackos rave about p21s and I was not impressed by it. I have been using Sonax in the US. It works much better than the US version of p21s.
