Hi Adam,
Just came across your post, as I seldon view this section. As regards carpet cleaning training, for what its worth when my brother and I started carpet cleaning in the early 1980s, there were very few companies then doing training. However, we were recommened the training courses in carpet and upholstery training run by Prochem and its founder Ron Tilley, by a chemical suppilier we used at the time. All I can say is the training given By Ron back them was first class and Ron covered all aspects of carpet cleaning on the training courses he ran. He had a great knack of imparting his wealth of cleaning knowledge in a friendly and informal manner, which as a cleaning newby, helped us a great deal. If Prochem still carry on their training in the same manner I don't know, but I hope so. I am hoping to go back to Prochem later this year to see if their training is still as good as the "old days". As you say there are now a far bigger range of companies offering training and I do feel being trained to a certified level such as the NCCA, TACCA and IICRC courses are very beneficial to have as you progress in the business. But as a new starter I would recommend looking at Prochem.
Good luck Phil Pettican
