Traditionally, the actual cleaning process was carried out at centralized "factories"; high street cleaners shops received garments from customers, sent them to the factory, and then had them returned to the shop, where the customer could collect them.[link widoczny dla zalogowanych] This was due mainly to the risk of fire or dangerous fumes created by the cleaning process. At this time, dry-cleaning was carried out in two different machines — one for the cleaning process itself and the second to dry the garments.
This changed when the British dry-cleaning equipment company Spencer introduced the first in-shop machines (which, like modern dry cleaning machines, both clean and dry in one machine). Though the Spencer machines were large, they were suitably sized and vented to be fitted into shops. In general, three models, the Spencer Minor,[link widoczny dla zalogowanych] Spencer Junior and Spencer Major,[link widoczny dla zalogowanych], were used (larger models, the Spencer Senior and Spencer Mammoth, were intended for factory use). The cleaning and drying process was controlled by a punch-card, which fed through the "Spencermatic" reader on the machine. Also, Spencer introduced much smaller 6 kg capacity machines, including the Spencer Solitaire and one simply called the Spencer Dry Cleaning Machine, for use in coin-operated launderettes. These machines resembled coin-operated tumble dryers; to be as small as they were, they simply filtered used perc, rather than distilling it like the commercial Spencer machines. Solvent had to be changed far more frequently as, without distillation, it quickly became discoloured and could cause yellowing of pale items being cleaned. A coin-operated version of the Spencer Minor,[link widoczny dla zalogowanych] which automatically carried out all the distillation and solvent-cleaning operations of the standard version, was available but rarely seen, presumably[citation needed] due to its greater cost and size than the other coin-operated machines.
