Clean an Extremely dirty acrylic tank

My parents bought me a 50 gallon tank and cabinet stand at an auction for $5. They are bringing it to me today. Woohoo! First I am filling it with water to see if it leaks. Then I need to clean it because it is aweful looking.

I know I can't use soap or abrasive scrubbers. I don't think water will get off the dirtiness. Any suggestions? My mom said it is acrylic. Thanks!

 

Vinegar, hot water, and an acrylic-safe sponge will help!

Can't be just any old dishwashing sponge, though, even if it is acrylic-safe. They'd have to buy a new sponge for fish-only purposes and never use it for anything else, because, you know, soap.

Welcome to the forum, Misscap!

Wishing the best for you and your fishies!

 

Acrylic-safe sponges are sold as aquarium stores - not sure any ordinary sponges will do (also most say don't use for aquariums). That's why I didn't say kitchen sponge

 

Depending on what is the "dirt" I use vinegar and hydrogen peroxide. If it's biotic I use hydrogen peroxide and then vinegar for hard water and everything else, I use a clean rag and elbow grease, rinse frequently.
