Indeed,there's no way to repair a damaged groove.
There are a LOT of products, solutions, machines on the market to clean. Here are some advices:
MAIN TIPS FOR KEEPING AND CLEANING VYNILS
First, a tool to use each time you play your record, is the felt brush, like the one pictured below. It's much better than the cloth cause it doesn't loose it hairs. This kind of brush removes both dust and static electricity.
There's no specific brand, but the one provided with the "Metanac" (see further, and picture below) is good.
TO CLEAN THE VYNILS:
There are many products. The "Metanac" is a good and efficient product that you simply apply directly on the record with the felt brush.
Another way is to do his own cleaning liquid, proceeding as follow:
-1/3 90°c alcohol
-2/3 distilled water
-A few drops of neutral soap (without detergent, very important).
You have to wash your records with that liquid, using a soft matter to softly rub, or throwing the liquid on the vynil using a kind of water gun. Then there's the drying issue, which is to find a way to remove water without adding hairs by rubbing with a cloth.
Then, for the cartridge keeping, there are two things:
-Cartridge demagnetizer (any brand, make a search on the net). You have to do it from times to times.
-Cartidge stylus cleaner liquid (any brand, make a search on the net). You have to do it from times to times.
Here are the main products to start, considering that there are many products, solutions for it.
There are even sophisticated and expensive record cleaner machines.
