What I've found that works the best is to use the Mother's Back to Black CLEANER...not the normal B2B product but the cleaner. Then is use a product called Solution Finish. It's the best product that I ever used. It's about $30 on Amazon for the 12 oz size. I bought it in 2015 and still have over half of the bottle. I've done 2 VXs with it and given some away. It goes a long way and last a long time.
