Shurhold Series Multipurpose Marine Cleaner - SMC Concentrate - 1 Gallon

Shoe marks are tough, but this does the trick!

While it cleans well, I found that it's not "spray on / hose off" as described on the bottle. I tried a garden sprayer with 1 to 4 ratio as directed. Sprayed the some of the boat bottom, waited a minute the sprayed off with a hose. Nada. Still stained and dirty (but just a film. Not like it was years of accumulation) so spraying on / hosing off won't get the job done. When I switched to a bucket and bristle broom grime started coming off fast. So, took a star off because the directions are incorrect. Still, I'll be purchasing more when I run out so I DO RECOMMEND.

Ease of use and finished product

One of the best all around marine cleaners I have used. The best part about it is you only need one bottle on the boat. You can use it on paint ad gel coated surfaces, glass, electronics, wood, Formica, vinyl, metal. One cleaner for all surfaces! Even in the engine room.We had an exhaust leak and when we got back in and to cleaning up the engine room everyone was telling us how hard it was going to be to get the diesel soot off of everything. I mixed up an extra strong batch of SMC and sprayed down the engine room, let it sit a couple of minutes and for the most part just rinsed everything off. A few spots need a second application and some light scrubbing with a brush but it made extremely quick work of cleaning up a very dirty mess.

Worked well Hard dirt didn’t come off

This is the second bottle of this shipped to me. Both times the bottle has been cracked and I’ve lost the product as it was on its side in the box. Unfortunately, I’ve been out of town both times it was delivered and the return window has closed to return it. I love the cleaner for my boat, I’m just tired of cracked, thin, hard plastic containers.

This cleaner works as advertised. It is great. I have a 10 meter 1988 Trojan International Express Cruiser and this is the only cleaner that I use on the exterior of the boat. Be sure to follow the mixing instructions of 1 part cleaner to 4 parts water and follow the instructions on how to use it.. It is a strong concentrate. Much cheaper to buy the concentrate and mix it yourself than to buy the smaller spray bottles of premixed cleaner.

Normally I am a big fan of shurhold products however this product does not stack up. there are better overall cleaners available on the market.
