Before applying new caulk, all existing caulk must be thoroughly removed. Begin by manually pulling off any large, already detached sections of old caulk. For caulk still adhered to the surface, you can score it with a utility knife to break its seal. A sharp painter's tool can then be used to scrape and break up the connection between the caulk and the surface. For areas that are difficult to clean, a specialized caulk remover tool can be effective, especially on hard surfaces like ceramic or porcelain tile. If removing caulk from softer surfaces like acrylic tubs, be extremely careful not to scratch or damage them; a plastic caulk remover tool might be safer. For stubborn residue, you can use isopropyl alcohol (91% or higher) applied with a spray bottle and wiped with a sponge, allowing it to sit for a few seconds first. Vinegar is another common household substance that can help loosen caulk. Some specialized chemical caulk removers like 'Goo Gone Caulk Remover' are also available, but carefully read their labels as some can damage acrylic surfaces. WD-40 is not recommended as it leaves a lubricant residue that prevents new caulk from adhering properly. A heat gun can also be used to soften caulk, making it easier to scrape, but use caution to avoid heat damage to surrounding materials.

old caulk before we can start applying this as far as removing the cot goes there's a lot of different techniques that you can use by I'm going to share with you the ones that I know work for sure so the first thing you should do is when you're removing the caucus to try and remove any large sections of caulk that you can that are already detached now anything that's still adhered to the surface you still need to get rid of you can't just caulk over it you have to make sure the surface is completely free and clear of any type of old or any old residue so you want to be sure to remove that as best as you can the most common way to get rid of caulk is to either score it with a utility knife or you can even use a sharp painters tool to kind of get in there and break up that connection between the surfaces and the caulk itself once you do that you should be able to remove most of it now you're still going to have some residue left over that you're probably going to have to scrape on a bit in order to get it completely removed but the painters tool works really really well in this case now if you're removing caulk from something other than porcelain or ceramic based tile you're going to want to be really careful that you don't scratch the surface with any kind of a tool that you use to remove the caulk things like acrylic tubs can be really easy to scratch scratch and damage so you want to make sure to take your time here and not get super aggressive with it they also make a specialized caulk remover tool that you can get now this can be a great option especially if you're removing the caulk from ceramic or porcelain tile if you're going to be removing it from other surfaces I'd be really careful because again these blades can be pretty sharp and they can damage softer surfaces now I will say while these can be a Time Saver you're still probably going to have to remove the rest of the residue with some other method either Again by scraping it off with a putty knife or some other techniques that we're going to talk about here you can use a special chemical that's designed to help you remove caulk but you have to be careful because again if you're removing caulk from something like an acrylic based tub some of these cleaners some of these caulk removers can actually eat through those tubs and destroy it so you need to be really careful and really read the fine print on those caulk removing chemicals now in addition to these harsh chemicals there are also some…
