Elsan Double Blue Toilet Fluid Caravan Motorhome 1L
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.
And because it is concentrated, it also takes up less valuable storage space. Elsan Double Blue is also pleasantly fragranced, non-staining and suitable for all chemical toilets and cassettes.
