    Hi, as shown in the picture of this thread are static lines, coming from a dirty VHS, isn't it?

    Because at one point of time while playing the VHS, the blue screen with the text "VIDEO HEADS MAY NEED CLEANING PLEASE INSERT HEAD CLEANING CASSETTE" actually appeared. So, i was wondering as to whether this method is the right one to get rid of those static lines?

    I'm not so sure it's the VCR or tape that's dirty. Sometimes a VCR gives out that warning simply because it doesn't like a tape.

    At any rate, you have three options if you do indeed want to clean your VCR:

    1-(OK IMO) You can use a cleaning tape (but many have varied opinions on this, dry and wet cleaners)

    2-(BETTER IMO) You can try cleaning the VCR by playing a brand new blank tape for an hour (depending on the tape length, this could be good for a couple of separate cleanings, but dispose of the tape after done).

    3-(BEST IMO) You can actually open up the VCR and go through a few tutorials on YouTube on how to clean your VCR, which are also very similar to that link you posted. So yes, IMO, I think this is the best method.

    If cleaning doesn't help, and you know AviSynth:

    If you can adjust the tracking where it's not so bad, just a few random white streaks, this is easily corrected by capturing the tape three times and using median methods with AviSynth.

    If your tracking works best on one part of the picture, and another tracking scheme works best for the other parts of the picture, then you can capture it with each tracking scheme, and combine the pictures later with Avisynth and StackVertical and/or StackHorizontal.

    Or, with tracking, if you can get the fuzzies to be in a small part and edge of the picture, just crop them off after capture.

    Hmm.. As to the link i posted for my method to get rid of the static lines, i think i recalled somewhere that it's possible to use Baby wipes / wet tissues to clean a dirty VHS head?

    I would worry first if it leaves residue behind (lint, shreds, etc) or scratches.

    But, I've even some tutorials use a business card for cleaning on the big head drum. Strange.

    As for liquid, usually Isopropyl alcohol is sufficient, and safer than using water, or anything oil-based, etc.

    I assume this would work?



    But replace the cotton with baby wipes instead?

    Ok, confused me here. I thought you wanted to clean your VCR first.

    But the VCR is the first thing you should consider in this case. Did you clean the VCR first? Did you try the tape in other VCRs with the same problem? Is the tape visibly dirty or do you know for sure?

    Just because a tape doesn't play well on one VCR doesn't mean the tape, or even the VCR, needs a cleaning. Cleaning a tape is really a last resort since this is your video source, and a rather extreme measure, and only should be done if there's no other solution.

    As for baby wipes, not sure, but doesn't sound like a good idea when dealing with magnetic wares like tape itself. Hopefully someone has a better answer on this for you if you indeed decide to clean the tape.

    If you really need to clean the tape I'd suggest you try this first, for experiment, on a tape you do not love to see what happens.

    NEVER use Baby Wipes!
    There is crap chemicals in there that will ruin a VCR. For example, Aloe.

    Never clean a tape unless properly trained. You'll probably just mess it up -- it's VERY easy to do!

    The first course of action would be to simply try another VCR.

    If I recall, there seems to be no mold at all on the tape but I don't know why the static.

    It's not "static", it looks like a tracking issue. Have you tried to adjust the tracking control ?

    I agree with Lordsmurf: don't even attempt to clean either the VCR or tape unless you have done all the research and know thoroughly what and WHY you're doing, and you have the proper tools. Otherwise, you will end up with a crapped VCR and crapped tapes, possibly even more than you started with.

    Baby wipes=BAD
    Business card=BAD
    Cotton swabs=BAD
    Head cleaning tape=still NOT GOOD
    Wet* head cleaning tape=NOT Optimal, but acceptable
    New, Blank VHS tape=Acceptable, but doesn't take care of many of the problems
    Lint-free foam swabs=GOOD!

    *Wet Cleaning solution: Isopropyl alcohol as sold in most grocery stores/pharmacies, etc leaves residue, so=BAD
    Freon TF cleaning agent=GOOD
    90+% pure, Denatured Alcohol=GOOD

    Accepting substitutes for these proper tools means opening the door wide to the possibility of accidentally ruining your own stuff.

    ************************

    I also agree with davenet, it looks to be more a tracking problem than "static" or a cleaning issue. Most cleaning issues affect the whole picture fairly evenly (slight, little bit more, little bit more, lot more, full blown snow). "Static" usually only occurs with EMI/RFI and you can usually tell when there's a foreign interference going on, such as a vaccuum cleaner running nearby.

    Could be the tape was recorded with a recorder that already had bad tracking, so adjustment might not completely rid the noise. Only solution then is to find a professional with engineering skills that can mod a VCR to match the tracking that you need.

    Agreee with Cornucopia and davexnet; that looks a lot more like a tracking problem than a dirty-heads problem to me. Basically, there's a misalignment between the angle of the heads and the angle of the diagonal "helican-scan" stripes on the tape, so the heads are only "seeing" part of each stripe. Cleaning the heads isn't going to fix that, unfortunately.

    You may be able to reduce or eliminate it by playing with the tracking controls on the VCR -- but a great deal depends on the source recording. If the VCR which originally recorded the tape had bad head alignment to start with, it may be so far out of whack that you can't adjust the tracking on this unit far enough to compensate. (Or worse, if the original recording VCR's tracking wasn't stable and kept wandering in and out of alignment, you might never be able to get a clean capture no matter what adjustments you make.)

    If you're determined to try cleaning the heads, then yes -- lint-free foam swabs and +90%-pure denatured alcohol or Freon-TF cleaning solution are the only things you want to be bringing nead video heads. (190-proof Everclear will also do the job, but there's far better uses for that than cleaning tape heads. ) A wet cleaning tape will do in a pinch, but it's not ideal. All those other solutions that people toss around -- business cards, cotton swabs, baby wipes -- will just make the problem worse, if not wreck the heads entirely.

    (...baby wipes?! Gotta admit, that's a new one!)

    Since Isopropyl Alcohol is used to clean vhs heads, I wonder if these two below can be used?


    This..





    And this..





    I have yet to make any purchases, just saw them in a pharmacy store.

    Both are not suitable for VCR cleaning because they are not pure Isoproyl alcohol but only 70% Isopropyl alcohol. The remaining 30% is water. You need 99% Isopropyl alcohol because the water part won't evaporate entirely and will leave residue on the parts you try to clean.

    At my pharmacy stores I have the ask for them to fill up a small bottle of it because it's not regularly on sale, only the 70% ones.
