## Description

GLB 71428A

Review: Small round granules - 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.
Review: Water - Perfect for emergency water purification

### ⭐⭐⭐⭐⭐ SuperShock
*by K***N on August 8, 2011*

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!
