GLB71428A Calcium-Hypochlorite Super Charge Shock, 1 lb

I did not use this for a pool... I saw a tiktok video wherein the guy used pool chlorine to clean his wood picnic table. So curiosity led me to try these shock granules because it was cheaper then buying a gallon of liquid pool chlorine/shock. I tried to dissolve the granules (little whitish bb-like balls) in hot water in the pressure washer solution canister. Mostly worked but I will do it on the stove the next time. I sprayed the fence completely and waited about 30min before rinsing off with the 4000psi pressure washer (cold water). AMAZING!!! The wood look like I just installed it from buying wood at the store. It's been over a year later and its just starting to look dull again.

Perfect for emergency water purification

Have an above ground pool and this stuff is great to put in the pool for a quick clean. No skin irritations and I feel safe using it with my 4 year old and her friends. Plus, it saves on the water bill and having to dump the water all summer. Great buy when purchasing online from Amazon!

One of the most important items to have around the house when an emergency happens, is the ability to provide drinking/potable water. This product has proven itself time and time again as a great way to do so. I recommend having a couple of these around the house just in case.

I purchased this product because the listing stated it was 100% Calcium Hypochlorite. It arrived today ... 65% Calcium Hypochlorite, 35% inert ingredients. Very disappointed!

What can I say, the item seems made well and seems to function properly. I will get some use out of it and if I have any problems I will update my review.

If you need to shock that pool or spa, this is the product to use.

I bought these for survival reasons to purify water. Works great, I wouldn’t be without them.
