I haven't posted in a while, so figured I'd make up for it with some good old fashioned pic/post whoring
Couple weeks ago, got an email coupon from HF about their handheld steamer. Had been kicking around the idea of getting one, mainly for my countertop grill cuz the plates never come 100% clean out of the dishwasher. Figured something like this would be good for cleaning small stuff like that.
Since you're 'supposed' to use distilled water to prevent deposits from clogging up the machine, I looked up some YT videos on how to make your own. Most people used a large pot of water, placed a smaller bowl inside, put the lid on upside down and fire up the stove. Water boils, collects on the lid, and whatever condenses drips into the bowl for you to use. Pretty easy, but the mod bug yawned. Saw some more complicated videos, one in particular where a guy used a throwaway pressure cooker, drilled a hole in the lid to screw in a barb fitting, use some tubing to connect to a copper coil in a small bucket as a condenser, that fed into a mason jar. Mod bug liked that idea
Wanted to keep it cheap, in case is was a miserable failure, so here's the route I went. I have an InstantPot with a pressure cooker lid. One of the pressure valves leaves a 3/8" hole when removed, so I bought a length of clear vinyl tubing to fit that. I have my old aux transmission cooler that I took out of the EXT (that I suspected had a clogged thermal bypass) and some 3/8" hose pieces left over. Grabbed an old 2.5 gallon bucket, drilled an outlet hole near the bottom and started piecing stuff together.
Had to cut the clear tubing at a 45* angle to insert it into the lid. Used short sections of the transmission line to use as couplers for the clear tubing into/out of the cooler.
Set up everything at the sink, since I figured there was going to be water coming out of the bucket, and if anything went sideways, best place for hot water would be right there. Setup a plastic bottle in the sink and inserted the drain tube after dropping the cooler into the bucket.
I had a bunch of ice packs, to brought them all out. Placed those around the cooler, and then emptied about 3/4 of the ice maker on top of everything.
Fired up the pressure cooker, and could slowly see condensation working its way up the clear tube. After about 10 minutes, there was a steady stream of steam pushing through to the cooler, and eventually through the drain tube. It started melting the plastic bottle as it wasn't condensing in the cooler at all. Switched to a glass that was nearby, and then noticed some goop starting to flush out. I had flushed the cooler with water to get the rest of the Dexron out of it, so I assumed this is what had clogged things up and caused the cooler to stop helping my transmission. Good old steam cleaning for the win!
I added some water into the ice bucket, and that solved the steam output issue, after a few moments, it turned into a steady drip, but some of that was due to the non-seal where the exit tube passed through the bucket. Used a water bottle to put a slight rise in the tube so the melt water didn't run down the tube where the distilled water was draining.
I still had some more sludge make its way out of the cooler, but the proof of concept seemed to work the way I wanted it to. As long as there was a decent amount of water to submerge the cooler, the steam condensed completely and the exit tubing wasn't warm at all. Just need to address that bulkhead to prevent leaking and I think I could boil off as much water as I needed without needing to add more ice. Doing this would have also saved my plastic bottle the first time around. But live and learn.
Granted, I don't NEED a ton of distilled water at the moment. This steam cleaner only holds ~12 fl oz at a time, but if I ever buy something for larger jobs, like steam cleaning the floors or upholstery on the couches or anything like that, having a gallon or 2 at the ready, or being able to make enough ahead of time would be quite convenient.
Was able to clean out the glass with some Dawn and hot water, and I had a pipe cleaner that took care of the tubing, so the only casualty was the plastic spray bottle.
