Yes a large number of our laundromats around NZ have a dedicated animal blanket washer.  These are 28kg super large washers that have special Pet Blanket Wash Cycles (warm or cold) for $10 a wash. These wash cycles have 2 extra pre wash steps and 1 extra rinse step (total of 3 wash steps + 3 rinse steps). These heavy duty wash cycles can be used for extra dirty laundry as well. Please refer to our website to see if your nearest laundromat has one available.
