2002 Bayliner Capri 2150. I read somewhere that muriatic acid (can be bought at HW stores) will clean algae off the bottom. Is it safe?
Its safe for the fiberglass. Its not safe for you, your trailer's finish and any plant life it might drip on.
Wear goggles, gloves and dispose of properly.
Now, while muriatic acid works great, its usually reserved for those hard brown waterline stains that nothing else works on. A pressure washer oughta make quick work of algae. If you don't own one, you can rent one. I'd try that first.
Thanks. I do have a pressure washer and use it first. I was buying ToonBrite for fiberglass but it went from $30 a gallon to $50 this year. Since I like to leave my boat in the river for weeknight use, it gets pretty bad at times. I have been trying to find either the ToonBrite or the Zing Ahead cleaner on-line in something larger than a gallon, but so far no luck.
Capt Phab makes a great bottom cleaner, it's the only one I use, it's not as harsh on the environment,and your lungs, if you do use muriatic acid make sure you are up wind,myself I would not use muriatic acid I would use the Capt Phab, it will also remove the "tea staining" that you get sometimes when your boat sits in mineral laden water (water that looks brown) also the Capt Phab is thick and wont run off as soon as you put it on like the acid would.
