So I think you know this guy but forgot his ag name. He has like a black BMW z and his favorite wax is fusion. He taught me how to soak it in mineral spirits for 12 hours then rinse it out and then soak in alcohol or isprorply however you spell it for another 12 hours. Then rinse out
That's me, but I've combined the IPA / mineral spirits into 1 soak
I have found only one way to completely remove all / any LSPs (including sealants and tire shine) from applicators / pads. Most of these will come out brand new looking and 100% free of all polymers, sealants, silicones, etc... using this method.
Before you start, get as much product out of the pad / applicator using APC / pad cleaner you can - don't use dishwashing liquid / Dawn. You will never get it all out of the foam and it will NOT remove 100% of sealants, silicones, polymers, tire shine, etc... Then:
1. Get a small plastic bucket and lid, about 1/2 - 1 gallon size. You can get these in the paint department of anywhere that sells paint.
2. Fill it only enough to cover your applicator pad with a mixture of 50/50 mineral spirits (oderless)/IPA
3. Place rubber gloves on your hands and agitate applicator / pad in the mixture for a minute.
4. Let applicator / pad soak in the solution in the bucket (with the lid on) overnight.
5. Re-agitate applicator the next day in the solution. Then rinse the applicator and squeeze it out in hot water. Rinse it well.
6. Place the lid on your small bucket with the mixture of "cleaning solvent" in it. Save the mixture. Even though it will have sealant in it, you can use it several times.
While this is not a fast or cheap way to do it, it really works well. I just can't put a pad / applicator away that still has product in it. Some people just put the applicator in a plastic bag and save it for next time. However, I don't like this method, as I sometimes use the same applicator / pad for different products. Also, the foam does get dirty, even if it's just picking up surface dust, it does accumulate.
This method is not required for polishes or compounds. Most of them will come out of foam with pad cleaner.
