When my pool service closed my inground pool, they were unable to remove 8 of the loop-loc anchors in my concrete deck. Some of the bolts are stripped so they couldn't get them to budge when they attempted to loosen them from the concrete deck, and some of them just wouldn't budge because the person who closed the pool tightened them too much when the cover was removed this Spring. Is there anything that I can spray on the ones that won't budge to make them easier to remove? Does anyone have any suggestions on how to remove the anchors that appear to be stripped so I can put another anchor in the hole that will work appropriately? I'd also like to know what tool to use to remove them since I don't want to have to pay my pool professional to come back out here. There are 8 anchors that are currently stuck so I'd like to get this fixed if possible.
