Cleaning External Tranducer

I have an external transducer that has some barnicles attached to the bottom surface. Will I harm the transducer if I scrape or use Muratic acid to remove the critters?

What material is the transducer made of?

Gently scrape, I'd say. I've seen bronze, plastic and hard rubber. The critters should come off easily.

Oooo. No muriatic acid on bronze. Maybe phosphoric or nitric. Muriatic makes chlorides, which are ugly. And dissolves one alloy out leaving something other than bronze behind. Just scrape it clean.

G'Day DRS,

If it is bronze it is pretty impervious to insult. As daddle says, scraping will get most of the crap off. We often soak our knotmeter impeller in white vinegar to get tubeworm and shell off its innards (easier than disassembly) and that would also work for a DS transducer. Don't knnow if it would remove the leftover "footprint" from a barnie, though...

Cheers,
