I have 200 bottles of this Redex Diesel System Cleaner, which my autistic son accumulated in our garden shed when he bought his first car, a 2nd hand diesel.
Without asking me, he thought that he should add a bottle each time he visited the garage. We are now moving house, and have no storage room to keep them.
