Don't worry, I don't want to put stick or tab in the niche. I was searching for how to take the light out of niche and the last post mentioned blasting water around the light for 3 days in a row before taking it out.
Day one stuff came out around it. Day two did, then day three the flush was clear. When they finally got the light out the niche was clean.
So I'd like to give it a try till I can get a helper to help me get the light out.
Explain to me how the poster used their vac hose to blast the light housing if you would please?
