Pur Kleen Descaler or Old Orange Juice

[Bushbeater]

Had planned on taking my old Fish and Ski in for service today, but decided it needed some cleaning first. I had a sample bottle of the Pur Kleen which I proceeded to use on the lower unit. After a few sprays and some elbow grease the scale was not affected but I was getting paint on my scrub brush and wiping rag. At that point my better half decided to help and came out with a tub of old orange juice. In 15 minutes she had all the white scale off the lower unit and was cleaning the transom. Who wooda thunk it.
