I brought my classical records out of long storage, and was pleased that the ones I had cleaned with my VPI machine 15+ years ago (and kept in boxes in climate controlled storage) still sounded great. And the VPI still worked as well. I bought some of the MoFi cleaner (both the super and the regular...all of which is the same as the RRL, I think), and some new sleeves, and started acquiring more Lps (mostly 2nd hand). The VPI and the MoFi have worked great. They can't cure a scratch, but they can get the crud up almost always, giving me very quiet surfaces, and the process is easy.
I've never tried steam, so I know nothing about it.
