I had some 'shadow' staining on chrome that persisted, no matter what I used on it. A dab of Metal on a MF cloth, with minimal elbow grease added, and it was gone. I'm very pleased with this product.
Having used several metal polishes over the years, I thought I had found the best, I have been using the same product for the last 20+ years. Then I gave the M & K Metal a try. To be honest, I wasn't actually needing it, but helped boost me to the next level for freebies in my order. But having used Metal on my Porsche Boxster exhaust tip...... WOW..... so clean, bright & shines like new. A bonus is it stays cleaner, for longer. I haven't had to re-polish yet after several weeks.
Ohh did I mention I love M & K Metal ?
I used it for the plated part. The dirt was easily removed and the towel turned black.
Very easy to apply. Great results
