sort of the first step now okay and then once you uh pull that caulking out i like to use a plastic putty knife the beauty behind these is they actually have a pretty good sharp edge on there but it won't scratch the tile and it won't scratch the tub and so you're going to sort of take your time and dig out that old caulking and work your way you know between kind of digging out and if you see a spot maybe that the knife didn't get the caulking you can then take that knife again and try and clean up that area as as best as you can the more of the old caulking you get out and see that little gap that i'm creating that means that when you come back to re-cock it which will be a different video there's more for the new caulking to hang on to which is key you don't just want to put caulking over the old caulking because it just won't stick and it won't last and you know it's a good idea to keep the drain on the tub closed so that you don't put all this down the drain put a rag down over that and then you can sweep that up or clean it up and use that plastic putty knife again to kind of scrape away as much as you can with that sharp edge and you just continue to do this to go all the way around removing all the caulking that you cut out of there you may notice that when the stuff's really old it's very brittle and hard just take your time and clean it up as best you can sometimes if there's residue left in there where you just can't quite scrape it off there are some of these
