Grungy mini blinds need super strength cleaning. But professional ultra-sonic cleaning can cost upwards of $65 per blind. That's more than half the cost of new blinds! My blinds are too long to fit in the bathtub, so I built a soaking tank and cleaned all the blinds in my house for around $60. I bought a 10-ft. section of 6-in. diameter PVC drain pipe, along with two cleanout adapters and caps. Start by applying PVC primer to one end of the pipe and the inside of the cleanout adapter. Then coat the pipe and inside of cleanout with PVC cement. Here are more mini blinds tips and fixes. Photo: Kevin Sweeny
