          A:  I had no luck with it. I had removed the main caulk stripping from my shower and needed to get rid of the old residue before reapplying new caulking. It did not help at all

              A:  I used KRUD KUTTER on a fiberglass tub and it worked as specified. I first followed the directions on the bottle and tested it in an inconspicuous area before doing the grout between the tubs top surface and the wall tile. It came out fine.

              This helps
              I wanted to remove the caulk the previous owner applied with a shovel, and bought this product. Did it make the caulk melt like magic? No, I still needed razors, pliers, and a caulk removing tool. Definitely helped make it a little bit softer.

                Works great
                Works exactly as intended, just let it sit for a while before attempting to remove the caulk.

                  No odor, biodegradable, environment friendly
                  Fix up for poor work on a drop in sink where the silicon stuck to the sink but not the cabinet. Don’t trust the instruction times. You have to leave this soaking for a long time- silicon adhesives don’t peel off unfinished porcelain easily. Squirted out nice and thick. This variety of silicon remover is biodegradable and has surprisingly little odor if any at all. It's an earth friendly option (a little more time and effort). There’s a learning curve and you need the right tools- especially for corners. Due to leaky shut off valves, I did this without removing the sink. The picture is from under the cabinet. You can see it is not as simple to scrape out from the recessed crevice next to the flat surface. Overall, not too bad

                    Removed caulk but not the residue that was left behind(Reminds me of the gunk left behind from a sticker, but way stronger.) However, this made removing caulk easier than without. If you have removed the caulk & looking for something to remove the residue, this might not do the trick.

                    We appreciate your feedback, Jeremi! Once the caulk has been removed from the surface, we recommend repeating soaking with Rust-Oleum Krud Kutter Caulk Remover as needed to remove any stubborn residue on the surface.

                    Worked really well on latex and silicone caulk. I found after scoring and applying I needed to wait about 30 minutes before attempting removal. I used a utility knife, single edge razor blade scraper and a metal putty knife I sharpened. Follow directions on the bottle and you will be good to go.

                    Felt compelled to write review mid project-- removal of mildewed caulk in 2.5' x 6' walk in shower just installed in 2015. Mix of latex-silicone mixed caulking and silicone caulking. I like Krud Kutter products in general, bought because it was my only option as I have used different products for same task in the past with straight latex caulk. Followed directions on packaging, scored and removed as much caulk as possible, spray, sit, scrape... repeat....multiple times. I found it works better after multiple applications and maximum wait time. It helps to have a scrubber of some sort and for me has worked better to focus on small section at a time versus whole area.I will probably need whole bottle to complete a small job. What I expected to take a few hours to complete has turned into a multiple day project. I did not expect caulking to come off miraculously ,but also did not expect job to take up so much time.

                      Krud Kutter Calk Remover Works Kinda ! Spray is a gel needed to sit for a while on dried caulk and scrubbed with a brush etc. Fresh caulk it worked much better, but if its fresh warm water or mineral oil is better. Dried silicone no good on dry fresh was ok. Foam sealant fresh stains works great dry not so much . So all in all this works well when cleaning uncured product ,not so well on dried. Its non toxic and Biodegradable

                      Thank you for your feedback, Frankie! When removing dry caulk or sealant with Rust-Oleum Krud Kutter Caulk Remover, we do recommend to scrape, cut, or pull away any caulk that can be easily removed and score the edge of remaining caulk. Please keep in mind that the product may need to be allowed to soak longer depending on the condition and the amount of sealant on the surface.

                      Grouting is easy and fun, but De-Grouting has always been tough. With Krud-Kutter grout remover allows me to un-grout with ease. We love the ease and quickness of this. I just sprayed the gel like substance, let it sit ten minutes, and it came off very easy with a grout remover(see pictures below). It will work on many surfaces, and many types of grout. Always do a test area in a remote area first. But, you can get years out of the bottle. First I sprayed the gel like spritz, waited 15 minutes and scraped it off.

                      Cleaned Up last bits of silicone caulk
                      After I removed majority of caulk I applied Krud Kutter Caulk remover on the little bits of residue. I did need to let sit for 20-30 minutes for it to come off easily by wiping, otherwise I used a dull plastic scraper. Stubborn spots I reapplied twice. This did absolutely nothing to the grout so no worries about softening the grout.

                        Didn't do well on silicone caulk. After 3 applications it only softened it a bit so still lots of scraping involved. Might work better on rubber-type caulks.

                        Oh no, not what we like to hear! Rust-Oleum Krud Kutter Caulk Remover is a specially formulated remover that aids in the removal of caulks and sealants from a variety of surfaces. For best results start by removing any loose caulk, then score (cut) the edge of the remaining caulk. Thoroughly saturate the caulk and allow it to soak for 5 to 20 minutes, or until the caulk softens. Scarp away the loosened caulk with a scraper, stiff bristled brush or flexible blade. Repeat as necessary to remove residue.
