Why not have a go its not hard, and the results are pretty good IMO, all you need is a cheap wet/dry vacuum, some duct tape to blank of the end of the hoover attachment and some glue to fix the velvet ribbon. I used a carefully held curved flooring stanley knife to cut the slit (be very careful it does not slip), the slit only needs to be about 2-3mm wide.
Order some 99.9% Isopoyl Alcohol, get some Distilled water, and some bottles, these are great

https://www.ebay.co.uk/itm/VINYL-REC...oAAOSw8d5ZS-LT mix up some cleaning fluid to the correct mix and off you go (I have found about 30% Isopropyl to Distilled Water works well. In 500ml of cleaning solution you only need 2.5ml of the Ilford wetting agent, it is important as it breaks the surface tension of the fluid and allows it to enter the grooves and free the dirt, and for it to be removed easier with the hoover. The brush to gently hold on the record and spread the fluid is one of these cut into 3
https://www.ebay.co.uk/itm/Paint-Pad...UAAOSwv0tVJBE2, after cutting make sure that you use a small clean brush to get rid of any small bits of plastic before using and keep fingers off the pad head, regularly hoover it off between cleaning, when it starts to discolour throw it away and start with a new one.
Hoovering will get about 99% of the cleaning fluid off so any residual gently remove by wiping around the record with one of these
https://www.amazon.co.uk/Extra-Large...ds=micro+cloth and change them regularly as they will get dirty. If you wash them out then rinse them in distilled water, no soap products and leave to dry naturally.
In extreme case I have found that some really dirty records can take 3-5 cleans, if a record is obviously dusty and dirty then I will clean it first using a mix of L'Art Du Son first
https://www.amazon.co.uk/s/ref=nb_sb...=1ED0A3N2O5B4D and then rinsing with distilled water, and then clean with the above cleaning solution. I suspect that the L'Art Du Son has some form of detergent in it that helps remove tobacco smoke residue and grease, I keep separate brush pads and microfibre for use with this solution. Some people don't like L'Art Du Son but it seems to be a very effective cleaner IMO, but make sure you rinse the record after to not leave any residue behind.
Remember if you are disappointed after your first clean of a record do not give up on it, it may take several cleans before it gets really good. Even though it looks clean you can still have dirt left in the grooves causing crackles. Having said that if the record has marks/scratches across it and you can feel these with you finger tip then these may be the issue. But you'd be surprised, I have some records that if you looked at them you would say that they will sound bad because of the marks on them, but when played they actually pretty quiet. I know some people advocate cleaning a record before playing because they believe it immediately becomes contaminated once out the sleeve. Personally I think this is a bit extreme, but I do think that cleaning after 15-20 plays is worth doing. After cleaning pop into a new sleeve liner like this
