Follow the Manufacturers Instructions :
On going Cleaning/Care Instructions. Heritage strongly recommend that the tub is cleaned after every use with an acid free cleaner & wiped dry with a soft cloth. They recommend the utilization of VEA (Vitreous Enamel Association) approved cleaners. You can find these cleaners on the following website: http://www.vea.org.uk/enamel-care-list
Use a soft cloth or sponge for brushing effect. Don’t use wire brushes, steel wool & abrasive sponge pads. Rinse thoroughly with water immediately after the application of cleaners & wipe the surface leaving it completely dry after utilization.
Do not allow cleaners to sit or soak on the surface & avoid drippings taps. Failure to do so may result in small brown particles building on the enamel surface of the tub. The appearance of these particles may appear to be rust spots due to the manufacturing process, which we employ rust spots cannot appear within the enamel surface. These spots will actually be a build up of limestone & ferrous residues.
