Hello Hello,

Our concrete pool deck is pretty grungy so we're going to pressure wash it tomorrow. The dirt comes off alright with a high-pressure hose setting, so I think our brand-new electric pressure washer (2030 PSI) will work great. Here's the thing: The washer recommends using special detergent or plain water. I want to use plain water because it won't mess up our supremely balanced pool chem. My husband bought some Scotts Outdoor Cleaner. It boasts "fast-foaming action" and seems to contain hydrogen peroxide as its main active ingredient. What kind of effect could this have on our pool if it gets in there? I don't want to take any chances, but my husband thinks I'm overreacting. (He has zero knowledge of or responsibility for the pool, but he also doesn't trust my intuition because "the manufacturer recommends...". He thinks that because the stuff is "safe for plants" it won't have any effect on our pool water. :suspect:) BTW, if I'm being unreasonable, please set me straight.

For reference, here's a link to the cleaner's label: https://www.scotts.com/sites/g/file.../Scotts/image/Scotts_Cleaners_1gal_Refill.pdf

On a side note, I plan to bring the pool up to shock level before the cleaning and hold it there for a day or two afterwards just in case any loose organics make their way into the water. That way, I can monitor my FC, CC, and OCL to make sure no nasties get a foothold. (I'm wishing we had done this when I was slamming right after opening, but procrastination is our household style.)

Urgh,

Hydrogen peroxide will neutralize the chlorine in the water.

The surfactants will make your pool foamy.
 
Uh, fertilizer, and all sort of things, are "safe for plants" but can absolutely trash a pool, in short order, so that logic is flawed (at best). If you can get your deck clean without detergent, no matter the ingredients, why subject either your plants or your pool to it? And "the manufacturer recommends..." can't possibly have anything to do with them trying to sell you stuff, can it? ;)

Unreasonable? Well, if I have to take sides, I say the one who maintains the pool is "Lord of the Yard and All Things In It!" Period.

You might hold off on your shock idea until a TFP expert weighs in. That might not be necessary, unless you're expecting a huge amount of organics. Pools are sanitized to handle such things, so maybe you're already doing what needs to be done.
