I did a complete detail two weeks ago (clayed, #81, and topped with #26). I just got some #21 that I'd love to try out and I'm wondering what the best way to remove the #26 is? I have a bottle of Sonus Paintwork Cleanser that I received as part of a promotion. A buddy of mine has a bottle of Meguiar's Medallion Paint Cleaner that he'd give me so I could do the job. Are either of these products right for the job? Is one better than the other? I don't need it to correct anything, I just want to remove the previous layer of wax to get a perfectly clean finish so I can try out this #21. Thanks.
