In order to clean your vinyl effectively using a goat brush is best because it is very soft and doesn’t scratch the vinyl being cleaned. There are many different brands to choose from and this brush has worked well for my albums. When using the brush you want to go in circular motion consistent with the groves of the album. If sound quality hasn’t improved repeat the process and depending on how dirty the album is a few times will be necessary. https://joeaudio.co.uk/products/joe-audio-premium-wet-goat-record-brushÂ
