Our pool patio area is stone with sand "grout". The sand has gotten moldy. Will this remove the mold? Will it remove the sand in between the stones?

It will work just like using a pressure washer without the flat surface cleaner except it covers more area at one time and Will keep it contained

I think bleach water painted on the sand joints may remove it after it sets & then is washed with just a garden hose before it drys out. If the sand grout is old some may be washed out {some}? with any pressure washer! A wire scrub brush could work with bleach water also!

Yes, this little gadget help clean more with the smaller nozzle , definitely worth the low cost. Must go slow but better than just the nozzle alone.

Hi, I have an unground pool and the deck is called cool deck I think. Basically, it is a cement coating with texture and I have used concrete stain on it several times and can pressure wash it safely. I would recommend that you get some liquid chlorine at your neighborhood pool store and use a garden sprayer that you can pump and mix the chlorine with water- probably half-strength is sufficient. You can buy one of those pump sprayers at Lowe's that is made to use with chlorine for around $20. This is a great way to clean any concrete as well. I also recommend that you use the spray wand instead of the deck cleaning tool. This way you are able to control the pressure and spray pattern. The chlorine mix will do alot of the job for you and allow you to clean it with less chance of damaging the grout. Hope that helps! Tim

Jacqueline, I used Zeolite instead of sand and the only problem I had was some kept settling in the pool for several weeks after installation. It's been two years, no more settlement, and it filters better than sand(It's possible I may have put too much in to begin with). I can't remember how many sacks of Zeolite I used but it was less than the amount of sand required. Rodney Constant

It depends on how heavy your mold is, how long it will take, but yes, it does work, and very well. It dries the mold up so you can wipe it away.

Yes, Suzi. This is a good maintenance cleaner for your limestone and won't strip your sealer as it's ph neutral. Please, keep in mind that this is a maintenance cleaner and not a heavy duty cleaner so if you're looking to remove mold, mildew or soap scum, you would need to use something stronger like our Ultimate Grout Cleaner or our Intensive Cleaner.

Hard to say, but it works amazing on tile for mold. If you have mold, it should take it off.

this will do the job perfectly. buy a spatula and apply it. have had great success it filling gaps of that size around the pool.

My home has always had a sand mound system and PVC pipes. Our water has acid in it and we do not treat our well water. The stuff has worked for us. We have had no problem but we do not put a lot of grease or bathroom/kitchen chemicals down the drain either.

I remove it immediately...make sure the concrete is not too wet when you mix it! Shimmy and shake the mold as you pull up on it and it lifts up easily and fast!

I don't know your reason for purchase but I got this to kill mold in an old mobile home we bought? it did remove some but as for the claim that it will linger and kill the source I don't think so.

Not this. Just use a tile and grout cleaner and those Magic eraser sponges are awesome. Don't use simple green cleaner because it colors the grout!

It helps eliminate moisture in an enclosed area. Not sure about stopping mold; don't think so.

I do not have sand stone so I'm not able to help. I suggest contacting the company.

It should, most mold will fluorescent. However I don't think it will work all that well. I might be mistaken, but I believe that any mold on the interior side of drywall should be visible to the eye, and mold in the carpet fibers will mostly be removed by the vacuum cleaner. Its the mold inside of the wall cavity (very common because of poor vapor barriers and failed weather stripping) and under the carpet (in the reinforced webbing and padding) that you wont be able to see at all. You can check the drywall at the seams and edges, and you can leave the carpet un-vacuumed for a couple of weeks, if you have mold then that is the only way you should be able to detect it with UV light. Ammonia and other safer botanical chemicals can be used for the carpet, but the drywall will most certainly be ruined as the mold will be inside of the calcium sulfate substrate. This would definitely work for grout and tile, but the key is that UV light will only cause fluorescence in what the light can hit.

Yes, but I would spray it with a bleaching agent first. If there is some grout missing, sometimes the mold is not reachable without some type of fine instrument to help. Overall, this does a good job. You can work with it for about 10 minutes at a time and then you need to unplug it for a few minutes to refill. It heats up faster than you think, but you will be able to tell if too much water comes out. I did my shower while doing other tasks and went back and forth between the two.

Hi. It will remove most the seal and paint. There is a video on their website showing it remove permenant from grout.

It kills bacteria and algae...if your "mold" is bacteria or algae then yes it will stop that with weekly shocks during your summer months.

I was told it does remove mold particules in the air. So I believe the answer is yes.
