Large amount of deposits clogged steamer 

I purchased this Wagner Model 905 Steam Cleaner used. A short time after using it, I noticed little white specs of debris clogging up the spout. I would clear this with a toothpick. It got to where I was doing this every 5 seconds or so. I thought I'd better clean it. I put 1 part distilled white vinegar and 2 parts distilled hot water and filled the machine. I let it run with the cap loosened so it could steam completely out. You may have to loosen the cap more and more as it goes to keep the pressure up. Please use waterproof gloves and a rag so not to get scalded. Then tip steamer to dump out mineral and calcium deposits. You may have to shake it vigorously and put a plastic pick in there to work some debris out. Flush with water and repeat. If yours is as bad as mine then repeat the entire process till clean. Baking soda can also be used instead of white distilled vinegar. Fill the machine with hot distilled water. Heat helps to dissolve all the baking soda. Then1/4 cup baking soda. let sit in machine for 3 to 4 hours and then rinse with water till clean.
