If you already have a coal boiler, only use high-grade coal lower-grade coal contains high levels of sulphur it can corrode and shorten the life of the boiler. Unblock those drains with ease with the unblok sink & drain unblocker gel! it doesn't just work in bathrooms, oh no, it also works in kitchens too, so anywhere where you have a drain can be clean and freshened up after all, is there anything more horrible and annoying than a clogged up drain? We have a model.
