If you don't mind flooding your bathroom and having water dripping off everything in it, that's the entire Instructable... Skip the rest and go clean some records.
If, however, you want to keep peace with your family, read how I made a container to keep the destruction to a minimum. I pieced my container together with odds and ends lying around my shop, so you won't necessarily have the same ingredients as me. Use creativity to make your own container. The most important thing to remember is, you'll want to be able to clean both sides of your record easily.
Step 1: The Parts I Used Include:
2. You don't have to make a label cover, but I'm pretty sure a paper label would lose in a battle with a high pressure water jet. A 4-1/2" diameter wire spool is about the right size. Also, try to pick up an empty Cool-Aid jar. The cover is slightly smaller than the wire spool and is thick enough to hold the record away from the box wall so you can clean both sides.
3. Stuff to put it all together. Here's what I used: Plastic to make the mount, a 90 degree 1/4-20 threaded rod, a plastic endcap, a heavy plastic spacer, closed-cell foam tape, assorted nuts, bolts, washers and epoxy.
Step 2: Putting the Box Together
Cut the Cool-Aid container in half. As you can see in the pictures, I left the cover on the jar and cut at the point they met. This leaves a portion of the jar inside the cover, adding strength. Drill a 1/4" hole through the center of the top.
Next, cut the wire spool in half. One of these halves will be permanently mounted on top of the Cool-Aid cover. In order for the record to fit, the nuts holding it on need to be below the mounting surface. This is where the endcap comes in. These caps are commonly used to close up the ends of tubes and plug holes in sheet metal. Whenever I come across one, I'll save it. If you don't have any, you might try poking around an automotive or hardware store. You'll need something that looks like a thimble with a brim (or a mini stove-pipe hat). It also needs to be large enough to accept a 1/4-20 nut and socket-wrench socket.
Drill a hole in the center of one of your wire spool halves, large enough for the endcap to fit snugly. Place a steel washer in the bottom of the endcap and push them into the hole.
On the other wire spool half, you need to add something solid enough to withstand some compression. I had a spacer that fit perfectly, but anything with some beef to it will work. Drill a hole through the center, sized to fit a 1/4-20 threaded rod or bolt. On this spool, plug any holes where high pressure water can enter. I used marine epoxy. It went on smoothly and it's been holding for over 2 years.
Wrap closed-cell foam tape around the perimeter of both spool halves. This will seal the label from most of the water and all of the high pressure water.
You'll need a bolt long enough to reach through all of the components plus it's own mounting. I happened to have a SS 1/4-20 threaded rod with a 90 degree bend to it. I fashioned a mounting plate from plastic to hold it and was able to be bolted to the side of the case. A block of wood, with a straight bolt running through it would work just as well... Only one caveat... Use stainless hardware.
Once the bolt is mounted, slip the Cool-Aid cover and the spool half with the endcap onto it. Thread a nut onto the bolt and slide a wrench socket down on top of it. The socket will allow you to snug the nut into the endcap. When that's done, run another nut on top of it to lock them in place.
That's it. You're ready to clean records.
Step 3: Cleaning:
Put everything into the bathtub, or as in my case, the shop sink (had to have an Oral Breeze in there too... Power washing is a very, very handy thing).
If you normally use a wetting agent, spread it around before turning the power washer on. I wet the record and spread a small amount of Dawn dishwashing detergent on the playing surface.
Fire up the Oral Breeze and hold the spray at about 30 degrees to the record. By turning the record and spraying a pattern you can cover the entire surface in a few minutes. Try not to spend too much time near the center, as some water will make it through the tape and onto the label.
When you're done, pull the record out and dry it with a soft towel. Store the washing box away, or do as I do and fill it with cables or other home theater detritus... And then store the washing box away.
