Pickling agent is the top product for removing traces of dirt from dinghy tubulars. The power with which the pickling agent is able to act and clean any surface is really remarkable but don't worry. The pickling agent is made from acid and alkaline components that cannot in any way ruin the tubulars. In short, the pickling agent cleans and does not affect. On the contrary, the correct use of the pickling agent avoids the use of other non-specific products that could be too aggressive.
