Works!

This is my second order as the the first proved that it works!

So far so good

I have used the cleaner around the boat for a week or so and it works very well. I have used it on different surfaces and found it to be effective on vinyl seats as well. One issue I have noted is it tends to leave streaks on the outboard motor cowling.

Serious Multipurpose Cleaner

I have been using Serious Multipurpose Cleaner for about 3 years now to clean a number of areas of my boat and it works very well. I will keep buying it!

Problem solved

I bought a 10 yr old 31ft cruiser that only had 100hrs on it but shameful maintenance and care. Mold, grease, droppings of all kind, unknown substances, and things hard to describe. Someone left an almost empty spray bottle of SMC on the dock. I read the label and tried it. The result was just like the other reviews read. Five Star. It is hands down, with out a doubt, no questions asked, seriously the best cleaner I have ever used! For ANYTHING! I Immediately ordered a gal. of the concentrate. I was disappointed when my order arrived with about a third of the product having leaked out and all over the inside of the box. I liked the product so much that I just ordered another gal. Fortunately the second one arrived with no leaks.
The boat looks brand new, topside, below, bilge, hull, canvas, glass, upholstery. I found a bargain in both the boat and the cleaner. It's now my go to cleaner for everything.
