Hi all.
I'm not sure if this is of any interest, but......
Whilst waiting for the rust proofing to dry on Thelma's (my 1959 FC wagon) front floors. I turned my attention to the front seat. GMH called the material Elascofab, introducing it in late FJ specials with the two tone interior. It is quality stuff, it wears and lasts very well.
Thelma's front seat seat is pretty typical for these cars, 49 years and 120,000 miles old. It is sagged on the drivers side, where it is worn and shiny and the stitching on the pleats is coming apart. In short it looked terrible. The colour is Riff Red.
From past experience, I have learned that upholstery cleaners won't remove the ingrained dirt. However Jiff and Nifty will. I have used both. Jiff is very effective but it is abrasive and can damage the colour of the trim, if you must use it be careful.
Nifti is gentler, however, it will also affect the colour so test it on a small area which can't be seen first. In Thelma's case, though, the seat looked so far gone I wasn't worried. I spray two pleats at a time and use a hard toothbrush (this probably affects the colour more than the Nifti, but nothing else would remove the dirt). As soon as these are scrubbed I immediately wash it down with a Wettex and clean water. I don't let it dry on the seat and after finishing I wash the whole seat down with a clean Wettex and clean water.
I took some photos with the seat partially cleaned so you can see the result. (it looks better in the photos than it really is)
Here is the finished job, the red has lost a little colour but overall it looks good, so much so that I'm going to have the springs repaired, pleats restitched and use the existing vinyl
This really can revitalise an interior that looks beyond saving - and Nifti is cheaper than upholstery cleaner too
A word of warning though, don't be aggressive on the black parts, using a toothbrush can make the black go patchy, I just use a Wettex here.
I hope this helps
John
