Extreme Acid Wash the Bio-Dex Way: See the Awesome Results!

An Acid Wash is a great way to renew your pool’s overall look without re-plastering it. The acid mix will take off a layer of the plaster and if done correctly with the right mixture, it will also remove 95% of the metal stains and another staining. That is one reason I use Bio-Dex products when I do my Acid Washes. Their products actually do what they say, and you can see the stains coming right off the surface of the pool.
The Acid Wash mix is the most important element of Acid Wash. Here are the products that you need for a successful acid wash. You will need 31.45% Muriatic Acid mixed with water in a 2 to 1 water to acid mix. Bio-Dex Plaster White ‘n Brite to help thicken up the acid solution so that it runs smoothly down the walls of the pool and to reduce the acid fumes. Bio-Dex AquaDex 50 Stain-Off which helps to remove iron and another metal staining from the surface. If you use this Acid Wash mix you will have great results and the plaster or Pebble Tec will look as good as new!
You can prep the pool to remove some of the calcium build up on the tile with the Bio-Dex Protect-All-Supreme which will require you to raise the water level over the pool tile calcium line, pour in 1 or 2 gallons of the Protect-All-Supreme into the pool and then run the pool for 24-48 hours. In most cases, this is probably not something that most customers will opt to do since almost all of the acid washes I have done were in pools that needed to be drained straight away. But it is a part of the treatment and something that you can do as the first step.
Here are the detailed instructions from Bio-Dex on how to do an Acid Wash the Bio-Dex way:

Acid Wash Tips:
Always wear protective gear as the fumes and acid are hazardous.
The first thing you should know when you go to do an Acid Wash is that the results cannot be predicted. I can look at a pool now and pretty much predict the outcome. But each pool is different, and results vary.
You only want to Acid Wash a pool if the entire plaster or Pebble Tec is intact. This means no cracks or chips are present. And acid wash will make the chipping even worse so if the surface is full of cracks and holes in the plaster, I would pass on Acid Wash and move straight to resurfacing it.
You also do not want to drain and Acid Wash a pool if the air temperature is over 90 degrees as the surface can be damaged by the extreme heat exposure. Nor do you want to leave the pool drained for more than one day in hot weather. You also do not want to drain a pool when the water table is high- basically, if you have 3-6 inches of rain coming your way, do not drain a pool as it could potentially pop-out. You also don’t want to drain the water into an area around the pool. The ground can absorb the water, and this can also create a situation where the pool can pop-out. This is rare and something you really don’t need to worry about. You of course only want to Acid Wash a plaster of Pebble Tec pool and never acid wash a Fiberglass pool.
If the pool has heavy calcium staining on the surface, organic and metal staining can be trapped under the calcium. You can check for calcium before draining the pool simply by feeling the pool surface.
The basin in the deep end is very critical. I always add Soda Ash to the basin and leave the Sump Pump (Submersible Pump) running so that the acid running off the walls does not pool up and stain the plaster. If this happens, once the pool is filled you will see a discolored ring around the deep end of the pool. So, keep the basin filled with Soda Ash or Baking Soda to neutralize the acid as it runs into the deep end basin and out through the Sump Pump.

My boss can learn a thing or two from this video! Great work 👏🏽

[@dirkhartman9465]

Awesome results! I'm going to try this on my next job!

That is a great video I am going to try this before next swimming season thank you for sharing.👍👍👍👍

Wow, amazing results!!! 💪🏼💪🏼

Havew a beadcrete surface...what is your recommendation for that finish?

[@SPL]

You can safely acid wash that if needed.

[@garypick]

Hi, great work. For the calcium, you mentioned a soft mineral-based cleaner called ?????? I didn't catch that. I'm looking for new cleaners to remove buildup on brick and tile. Thanks.

[@SPL]

Biodex 300 Tile Cleaner works well.

[@TommyP-s9n]

Love your videos, but why would you want to protect and remove scale prior to an acid wash? Also, I found 8 ounces is way too much. It makes it too thick and very soapy.

[@ryanlundrigan2580]

does this method work for heavy calcium build up on pool plaster?

[@SPL]

No. For that you will need to power sand it or hire a bead blasting service.

[@ryanlundrigan2580]

@@SPL Thanks! Do you have any videos on the power sanding method?

[@alanevans6483]

I love the video! Does acid washing make the plaster more rough?

[@SPL]

It can be a little rough after an acid wash.

[@alanevans6483]

Thanks for the reply! Im assuming there would be little I could do to smooth out the roughness of the plaster after acid washing?

[@Andrew-vc5kk]

Look like new! Wow, What do you do with acid water mixture pump it to the street or a drain? Dose it need to be neutralized?

[@SPL]

Yes, it needs to be neutralized in the basin where the sump pump is with Baking Soda or soda Ash and pumped out to the sewer line.

[@garyfritter9150]

Can you address how to drain the pool before hand? How much risk is there with regard to hydrostatic pressure? How do I determine if that is a huge risk for me vice just draining the pool?

[@SPL]

The risk of the pool popping out is rare. The ground needs to be pretty soaked for this to happen. Like 6-8 inches of rain that day. So very unlikely.

[@itsamemario833]

Do you have your customer sign a waiver just Incase the pool pop out? How do you go about informing them about the risk? @@SPL

[@MrFlores78]

Do u have a video on how to clean scale on tile without having to drain the pool thank u these are very useful videos.

[@adamc9147]

Part of the problem might be the pool water might need to be drained if you clean the tile and have high calcium level in your pool then the tile clean job will come up even faster due to the high calcium level.

[@SPL]

That is hard to do if the build up is severe. That is why I showed the Bead Blasting option.

[@adamc9147]

@@SPL So true that's what I tell most of my clients. There isn't much you can do once the scale is really build up

[@johnsalt9864]

Great video. Do we have to relief the hydrostatic valve if we are doing it in 1 day?

[@SPL]

I wouldn't. Sometimes those can be tough to get back in.

[@johnsalt9864]

@@SPL Thanks a million

[@georgehernandez7619]

How many bottles of acid , stain off , and plaster white and bright for a 28000 gallon pool. Im going to use the 2 gallon watering pot method. thanks

[@SPL]

pretty big pool I would have 2 cases of acid on hand just to have enough - 8 gallons. although you probably won't use all of that. When I do an acid wash I always have at least 2 cases on hand. 1 qt of the Plaster White N Bright should be enough - again, I would have 2 qts on hand. And for the Aqua-Dex 50 have 2 qts on hand also.

[@georgehernandez7619]

Thank you

[@mairakhan3772]

Hello! I need help with pool can I have you look at my pool?

[@LsL7121]

Would this work the same with a pebble tec pool?

[@SPL]

In most cases yes with one thing to note - in Pebbletec pools there tends to be more calcium build-up so in some cases you will get even better results with a complete bead blasting of the surface.

[@KBP120]

Hey, do you know if is possible to use plaster white and brite to thicken liquid chlorine?

[@SPL]

Good question, you will have to contact Bio-Dex on that one

[@topnotchpoolservice6534]

Have you ever done the no drain deep clean by Bio-Dex? Just curious to see results. Thanks

[@SPL]

I've had good results with it for certain stains. But for something like this it wouldn't do anything.

[@edmondb851]

Would a 5 gallon mixture be enough to acid wash an approximatly 1K gallon, two-level spa? How much muriatic acid would you suggest?

[@SPL]

It probably would require 1/2 gallon of acid for that size spa or less.

[@jesuspazmino6948]

Will this remove rust stains

[@SPL]

Most of the time. You may need a little stronger solution over some stains.

[@curtdixon3]

Will acid washing remove black algae?

[@SPL]

No. You would need a chlorine wash first.

[@felixrachel]

Will an acid wash clear up calcium scale that is in the pebble finish crevices? I don’t have a calcium scale ring.

[@SPL]

More than likely not. In most cases with calcium on a PebbleTec surface the entire pool needs to be Bead Blasted. Very good results. In fact my dad just drained his pool again and is having it entirely bead blasted today. He does this every two years in Indio CA where the water is very hard.

[@felixrachel]

Thanks for the quick reply. I’ll look for somebody who does it in my area.

[@eagleone0123]

Can you recommend a bead blaster fellow in Rancho Cucamonga. Have calcium and stains in my pool. Thanks.

[@eagleone0123]

Would this work for pebble tech surface?

[@SPL]

Yes. It will work pretty much the same.
