Elsan special promotion twin pack double toilet fluid includes one 2l Double Blue and one 2l Double Rinse, making this great value for money.

Double Blue is double concentrated so whilst it gives exactly the same unbeatable anti-bacterial performance as Elsan Blue, it provides twice the doses making it especially good value. Elsan Double Blue is also pleasantly fragranced, non-staining and suitable for all chemical toilets and cassettes.
