How do I rejuvenate a Bonnet Insulation Pad

#1 Post by Topcat Tomcat » Wed Apr 07, 2021 4:49 pm

Is there an easy way to rejuvenate a Bonnet insulation pad?

I picked one up yesterday for the 45. It's basically in good condition, but it could do with cleaning.

I shouldn't think that it's a good idea to get too wet. I can't think of an easy way to go about it.

What type of dirt is on it?

General dry dust etc? (in which case I would suggest using a suitable brush and vacuum cleaner)

Or oily grime? (In which case I would suggest an aerosol foam degreaser)

You could still give it a full 'soap and water' treatment, but you would need to allow it to dry thoroughly (might be a possibility when the temperature outdoors finally gets above 15 degrees!) Just don't try scrubbing it too much, because that is what will ruin it.

It's probably a bit of both. I'll have a go over the weekend. 👍

You can't get it very wet as it's just recycled materials and it'll soak through and tear.

If you use a brush, use a soft-bristled one as if there's the slightest part of the pad where it's worn through and you catch it with stiff bristles, it'll tear a hole.

I tried a basic wipe over / dust off with a soft brush (and I was very careful, seeing how thin the surface had got in places), then I went straight to Auto Gylm's black spray dye (450ml aerosol).

I did 3 coats and used half the can. I stood the pad up on it's longest side as I prefer spraying vertical surfaces - and I definitely made sure everything behind the pad was masked off, as I'd have dyed a chair, a brick wall and a fair amount of gardening tools otherwise...

If you do a heavy coat it will definitely start to soak through to the other side and you'll see it. It doesn't ultimately matter as you don't see the other side once fitted. The only thing you have to guard against is spraying so much in one go that you make the pad go "soggy."

Leave it a good 1-2 days so the dye is fully dried out before handling and refitting. You don't want to be man-handling a wet pad and have it break up or tear. You also don't want black dye still wet and coming off on anything in the engine bay.

Results are excellent by the way. Like new.

I wouldn’t recommend vacuuming it - I did that once and as the pad is very soft it damaged it.

I had a few minutes spare yesterday, so I tried going over it with a soft brush which seemed to work quite well. There doesn't appear to be any real oil stains, so I might just try the dye.
