I always find they last longer if you don't leave product in the trigger head. So unscrew it, spray it back into the bottle, and then screw it back on :thumb:
These work fine for me with weaker acidic products like FSE or white vinegar. Don't know how they would handle a strong acidic wheel cleaner say, but so long as you empty the head after each use i imagine they'd be fine.
Same type as I linked above except from slims and like you i use tardis,wheel cleaner,strong degreasers never clean the spray heads etc and never had any problems.
