This machine works great, leaves vinyl records as though you just bought them. Deep cleans the grooves and removes dirt, dust and grime. Eliminates surface noise caused by sediment or dust build up. I used a mixture of 70% alcohol, spin clean fluid and a bit of clear, dye and fragrance free dish washing detergent. 50 year old records I have sound much better with no more pops due to dirt. Highly recommended, if you find an demo video on this machine, view it follow the instructions and you will have success so that you may enjoy your records for more years to come.
