No Nonsense Paint & Varnish Stripper 2.5Ltr (724GT)

Hello ClaireS, This should be used with wire wool as it can very corrode the wool which will leave brown marks on the surface you're using it on. If this isn't a concern that you can use it but if you're using it on something you don't want stained then you would be better of using a stainless steel wool. Thank you for using Q&A

Hello, Hard wax oil is essentially a combination of wax and oil. Regretfully we have not tested this product for its performance in removing either wax or oils from wood, so we are not able to comment on how well (if at all) it would perform. Generally, for the removal of hard wax oil it is recommended to thoroughly wipe with white spirits and then sand away the rest (the white spirit helps to remove the initial layer of wax oil so that the sanding sheets will not get bunged up with the wax oil). If you are resolved to try this stripper we would strongly recommend conducting a patch test on a small, inconspicuous area first, to ensure the finished results are satisfactory BEFORE applying to the entire wooden surface. We would also strongly recommend consulting with a tradesperson for additional advise how to best remove hard wax oil finish from wood. Thanks for using Q&A

Yes , just be careful if it is glass in a window frame , because it may attack the UPVC frame and if a wooden frame and putty is used , it may react with this .

Thank you providing this information , this tells me it is one of two things either not enough Stripper has been applied or not enough time has been given. Applying more Stripper is the only solution adding any water at this stage will only stop the reaction and cause the problem you are having
