If you are picking up groove dust after using the VPI, it may be coming from old inner sleeves. I recommend you buy rice paper sleeves and change out the old sleeve after cleaning your record. Also, I like multi step cleaning systems like Lloyd Walker's Prelude System. It's a bit more time consuming, but once cleaned, it will be a long time before you will have to do it again. You will get improved sonics and cleaner grooves. I used the solid stylus cleaner you are using years ago under a different brand name. It is supoose to last forever and it is suppose to be cleanable. I found it lost its tack after one cleaning and was of no use thereafter.
