Bio-Dex #300 Tile Cleaner, 1 qt. BD300

Great product, works well with Biodex pretreatment.

This product raised my phosphate levels to 1,000. Just be aware once u finished the tile cleaning to check ur levels and add phosphate neutralizer agents.I poured the Bio Dec directly on tile and after a minute used a power drill with brass wire brush attachments. Got 90% of calcium removed. Water here is extremely hard so build up heavy. I am pleased with result

I do NOT usually do reviews but wholly cow! I had one year of salt build up on my pool tiles and was planning to just scrub w the pumice stone to get it off, but even at that the line does not come all the way off. I looked at several of these kinds of products and read reviews and finally thought i’d give this one a shot.. Let me tell you! I LITERALLY wiped the product carefully on a hand towel over the line; it started coming off instantly.. however I willl say I think there was a dust coat on top that would come off easily anyway. I let it sit on the tile for a minute (probably should have done longer but was excited lol..) and it came RIGHT OFF.. as in a couple passes with the pumice stone and BAM! GONE! I’m floored. I HIGHLY recommend this product

This is the only cleaner that actually dissolves scale but it still a lot of work scrubbing.

Just noted a little difference.

A friend recommended this for car oil on the driveway and it’s amazing. I bought actual oil cleaner for driveways from HomeDepot and tried about 5 applications including scrubbing and it didn’t do anything. This stuff sat for a few minutes and you could see it turn oily. I scrubbed just a little and did it one more time (it probably wasn’t necessary) and all five of my spots came up—even on two different kinds of driveway cement. The area is a little bleached but all the oil is gone.

I purchased two bottles of this as I have a fairly large pool, and I live in Brentwood, Ca. We have very hard water (over 30 grains per gallon hard) and our pool had developed a pretty significant ring of calcium deposits around it. It looked bad, and I thought this stuff would help get rid of the hard water deposits around the pool.I followed the directions, and started working on one corner of the pool... 4 hours later, I gave up with this stuff.This product not only did nothing to loosen the deposits, the main thing it did was bleach the deposits super white... So after 4 hours of hard labor, my pool looked significantly worse than when I started. That was a fun Saturday!Seriously, Biodex 300 did absolutely nothing to clean up the tile...I have since gone back to Muriatic Acid and a straight razor blade gasket scraper... That sucks, but at least it works. I have spent quite a bit of time, and I am not done yet... But at least I am making progress! The Biodex 300 made absoluely no progress at all... My wife was almost crying when she went out to see how it was coming along and she saw the super white deposits left behind after I had worked for hours with the Biodex...Save your money... This stuff sucks worse than any product I have tried in years...

I had hard water Calcium build up on my pool tiles. I had to also use a pumice stone to help the process alittle bit to scrub it off. But this product made the scrubbing not so bad. It did most of the work but not all of the work. I had to scrub aliitle bit. My Calcium build up was pretty bad. I have used just a pumice stone on my pool tiles before WITHOUT this product, it was exhausting!!! This product helps you not have to scrub so hard, helps to loosen up the Calcium build up. I would definitely buy this product again!!
