Perhaps a new topic should be raised re: Dry cleaning, but I find the general misinformation about it, interesting to say the least.
Going back more than 30 years when I started, there were many Cotton Velvet and Viscose Velvet suites. The only way to Safely clean these is by Dry Cleaning, ie: using solvent, either by machine or hand. I used to hand clean them, until it became obvious that this was not only very unhealthy, but also leaving a solvent wetted suite in someones house was not the best thing to do.
Today there is much talk and promotion about dry cleaning, when in fact some if not all the processes include the use of 'Water', either as a concentrate in the container, or diluted in a sprayer or machine solution tank. No matter how fast these methods dry, they are not Dry cleaning, they are wet cleaning. They get away with it because no one has yet challenged them on the issue, it costs money to do so.
Following the Trade Descriptions Act some 30 odd years ago, carpet cleaners had to refrain from calling 'Hot Water Extraction' method 'Steam Cleaning' as the only steam generated was from the hot water and not a cleaning method. Some still ignore this fact today.
