Will this sandblaster remove hard lime buildup on a swamp cooler? I've tried everything from a wire brush to muriatic acid with little results.

I see no reason why it wouldn't. If sand isn't abrasive enough, you can switch to silicon carbide or other materials that will cut through the lime.

I would imagine so. It works well for removing layers of old paint. It needs a real good air supply @ 90psi though.

I used it to take thick rust off a trailer frame that was in a fire. Cleaned it up very nicely. I have also used it to remove paint and rust from the body of a truck before patching holes in the body. These were both done with play sand form Home Depot. The sand is a little coarse and sometimes clogs the gun but with enough air pressure I'm sure it will rip through some scale no problem. It's also going to eat rust, paint, etc

Have only used it on older rusted tanks. The brown rust turns a grey metal colour when I use caustic soda (NaOH) to remove the white sludge deposits. the The product works well coating for further use.I personally would rinse out with a grease remover such as acetone to make clean the metal for bonding. Good luck.

The sealer is very tough to remove and I have no idea if it will harm a good paint job. . I did not care as my tanks needed re-painting anyway. I did 2 tanks and both came out perfect. Make sure you do it right by the book and have a heat gun!

Yes. I use tap water and the demineralization cartridges and I have had no lime build up at all.

It might work if you are trying to remove a small rust stain from a bobby pin or bbs. My recommendation is do not let acid sit very long on the vinyl. I purchased it to use in a plaster pool and it worked well.

This is a great glass cleaner, but it is not a lime and scale remover. So if you have hard water and mineral deposits, this probably won't do the job. But if you want clean glass, this is the best stuff I have found.

I am not going to represent myself as an expert but, I own a Marina that does a lot of restoration on painted and fiberglass boats. If you use this grinder for buffing you should only do it at the slowest speed usable. This machine is a chain saw of sorts and will get you in trouble fast. The speed is the only unknown by me. I would tell you a orbital polisher is your best bet.

The steamer will certainly HELP break up the old mildew and guke but may NOT completely remove it. After steaming, I would go over the build up with a slightly scratchy pad and a product called "Eliminate" that you can get at Home Depot. Eliminate is similar to muriatic acid so use CAREFULLY - - - it is designed to cut through the white calcium build up that you sometimes see around pots on patios. It also works well to clean glass shower doors but - - - again - - - - wear gloves and don't get it in your eyes! Hope this helps - WO

Yea I agree with that previous answer, I was using it for my viquarium maintenance and it did take off the weaker hard water deposits but not the caked on stuff that you really wanna get out you know?

I'm removing the original paint on a commercial cart, the same one you see at Home depot. The paint is really tough to remove down to metal, looks like I'm using up most of the woven pad. And this is before using hand scraper, needle scaler and hard disk grinder. However Norton is the fastest but most expensive - it's a trade off. Next time I'll try torching the paint off then follow up with a diamond grinder.

I would think it would but I would be careful about etching the surface you are removing the lime deposits from.

I`ve used it on glass and other things. Its abrasive so it wont leave your glass looking pristine, but it will clean the hard water residue, it did for me anyway. Glass blocks are pretty tough... it should do the trick. If you are worried about scratches, try a little on one block.Can`t hurt. Its worth buying.

If the clog is from hard water as in lime and calcium buildup, unscrew the jets and soak then in CRW or Lime Away overnight. The buildup left over will flake off easily. Make sure to thoroughly rinse the jets before reinstalling

I know somebody that removed it from fiberglass - they used a plastic paint scrapper - it took some effort but it did not damage it. May be able to use wd40 or some other adhesive remover to make it easier. I have not tried to remove mine yet and I have a porcelain tub.

I tried it on the calcium ring around my pool. It was much slower to work than Muriatic acid and required more scrubbing. I'm going to try ascorbic acid next as KT suggested.

I live in a area where lime builds up fast. I use filtered water but it still builds. Once a month I run the tool to break up any build up. I unplug it then tilt the unit over the sink to drain it. I then unscrew the top two screws to clean the top container. I have used vinegar, and coffee cleaning products. Just be sure to run clean water to get it all out of the tanks. Most of the country doesn't have this problem but if you live in the south you may have to use bottled water if you don't want to really clean it. It makes great coffee I had mine for about three years.

I did just that this weekend. I put two thick coats of HNR then used dynamat extreme and it stuck very well. The only advice I could give is... make sure the surface is painted before applying HNR. You will see rust bleed through the next day if you don't. Happy sound deadening!
